About OmniSTAR OmniSTAR is World leader in providing high accuracy DGPS correction data via satellite channels.
OmniSTAR is a member of the Fugro Group with offices in the Netherlands, the US and Australia. A world-wide services and consultancy company with 160 offices in over 40 countries, the Fugro Group provides surveying, positioning and geotechnical solutions in both on and offshore applications. OmniSTAR provides commercial satellite DGPS services worldwide and is leader in the design and development of Differential GPS positioning technology.
OmniSTAR VBS and ‘High Performance’ (HP) solutions have been specifically developed to satisfy the requirement for high accuracy positioning systems and services in land based applications.
With worldwide satellite coverage, approximately 100 reference stations, 3 satellite uplinks and 2 global Network Control Centres, OmniSTAR provide consistent and highly reliable positioning services world-wide, 24 hours a day, 365 days a year.
Both OmniSTAR ‘VBS’ & ‘HP’ data services are broadcast by L-Band satellite transmissions from a network of geo-stationery satellites and are accessible for use by subscription. The services are unique in that they automatically provide the optimum position solution at the users location by means of a process known as Virtual Base Station. This method of deriving differential corrections is more accurate than competing systems dependant on data from single reference stations in fixed positions.
How it works OmniSTAR uses a network of reference stations (or base stations) to measure the errors induced into the GPS signal by atmospheric, timing and orbital effects. This reference data is gathered at Network Control Centres where it is checked for integrity and reliability and is then up-linked to a chain of geo-stationary satellites, which broadcast the data over their coverage area. This procedure ensures that all reference data generated for a given area is quickly available to the users receiver. The receiver processes the data from all available reference stations to provide the optimum position solution. Because all data generated at OmniSTAR reference stations is available to your equipment, it is possible to use all this information simultaneously, taking into account the distance between your position and the location of each of our reference stations.
This is done by mathematically weighing each reference station as a function of its relative position. The result is one set of corrections, optimised for your location, which becomes a Virtual Base Station. These optimised corrections are calculated every time reference information is received from the satellite. This makes OmniSTAR ideally suited to both static and dynamic applications.
OmniSTAR VBS subscription options:
Sub-meter Differential corrections
VBS Continental: Signal service available across an entire continent e.g. Europe.
VBS Regional: Service available across a defined region or country
Farm-License: Specific to agricultural users, a VBS cell is provided around the users stated location.
OmniSTAR HP Subscription Service: OmniSTAR-HP is the latest dual frequency GPS augmentation service in the OmniSTAR family of network GPS solutions. HP provides a robust and reliable decimetre level GPS service. By using dual frequency GPS receivers we can measure the true ionosphere at the reference and user locations, eliminating this error. When we use this ionosphere free measurement with information contained in the receiver carrier phase data in an intelligent way, we are able to create wide area positioning results of unmatched accuracy and performance. OmniSTARHP accuracies have been demonstrated as better than 10cm 95% (X/Y axis) and 20cm (Z) (2 Sigma).
The advantages of VBS and HP:
Both services provide consistent accuracy over a large area.
OmniSTAR services are highly reliable (not dependent on any single reference station).
No position jumps due to switching from one reference station to another.
World-wide coverage The OmniSTAR VBS and HP service is derived from several satellite footprints. This means that user equipment, capable of decoding the OmniSTAR signal, can be used globally.
Flexible subscription service OmniSTAR users can buy subscriptions annually or for multiple years. VBS user can also purchase subscription on a seasonal basis (minimum 3 months).
Reliability In addition to the implicit reliability generated by our Virtual Base Station technology:
All reference stations are dual linked to their respective NCC. The primary connection is by a leased line, backed up by a dial up line.
A primary and a secondary satellite service cover the most populated areas in the world. OmniSTAR compatible units are capable of locking onto the secondary service automatically in the unlikely event of a drop out in the primary service being detected.
OmniSTAR corrections are not dependent on any one reference station, but are weighted by the VBS algorithm. Therefore, a non-functioning reference station has only a minor influence on overall accuracy.
The European and African continents are covered by several satellite services. Automatic switching between these services is optional.
Thunderstorms or electrical fields do not affect the OmniSTAR signal.

Benjamin’s doctoral research focuses on information processing, a discipline where research is usually aimed at uncovering knowledge and technology that can be applied in other sectors. For example, his research may help improve the sensitivity of bio-imaging detectors, resulting in better diagnoses. In telecommunications, it may lead to energy savings by reducing the amount of power required for a given communications channel. In radio astronomy, his breakthroughs could make it possible to detect astronomical events even farther from Earth.
For his PhD, Benjamin plans to continue working on concepts he developed during his master’s degree to design new forms of classical signal amplification and to enable simultaneous optical signal processing in the time and frequency domains, making it possible to access information otherwise inaccessible with current technologies.

Advanced Security Acceleration Project for Smart Grid (ASAP-SG)June 12, 2013
- The goal of this project is to develop a set of computer and network security requirements for the smart grid deployment. The key problem addressed in this project is to provide actionable security guidance to utilities for secure deployment of smart grid systems.
- This is a utility-driven, public-private collaborative project to develop system-level security requirements for smart grid technology. The set of requirements developed in the project can be used by utilities at various stages of deployment including procurement, configuration, deployment, commissioning, and operation of smart grid systems. The ASAP SG project develops security profiles for Smart Grid applications on the basis of use cases established by industry working groups. A security profile makes this linkage explicit by identifying the systems and components (Logical Architecture) to be covered and their expected environments (Failure Analysis), delineating their expected and desired behavior (Use Cases), and assigning security controls (Security Controls) to those systems and components. A security profile also provides justification for control assignment (Verification & Validation) through presentation of the results of a failure analysis. Accomplishments to date include development of following security profiles:
- Advanced Metering Infrastructure.
- Third Party Data Access
- Distribution Management
- Wide Area Monitoring, Protection, and Control
- Substation Automation
- The security profiles produced in this project serve as guidelines for utilities and their vendors as they work to deploy a secure smart grid.

A harmonic nanomechanical oscillator with a high quality factor, weakly coupled to a single-electron tunneling device, can provide a strong feedback for electron transport. Strong feedback occurs in a narrow voltage range just above the Coulomb blockade threshold. In this regime, current is strongly modified and current noise is drastically enhanced compared to the Schottky value. In this project, we will investigate, how such a feedback mechanism could be taken into account in the design of an ultrasensitive mass-sensor based on oscillation of a freestanding carbon nanotube.
The feedback mechanism from mechanical motion back to single electron tunneling has been considered in carbon nanotube resonators. The feedback mechanism will affect, among other things, shot noise of electron tunneling. The feasibility of investigating this feedback effect using shot noise measurements at GHz frequencies has been considered. The conclusion was that the sensitivity of the present shot noise measurements has to be enhanced before such measurements are feasible.

Remote Control functionality is much better in ConfigMgr 2012. In ConfigMgr 2007 it was already a widely used feature, but it will be more used now! This because Remote Control functionality has more options available, which are very good.
The first one is named "Send Ctrl+Alt+Del key". In ConfigMgr 2007 it was not possible to remote Control a device, which was not logged-on. Then the Remote Desktop Protocol (RDP) was used to logged-on a device. It was also not possible to logout and logon with another user (for example: Administrator account). This functionality is available in ConfigMgr 2012 now!
The second one is named "Enable Clipboard Sharing", which becomes very handy when copy and paste actions must be done. Most of times this functionality is needed during troubleshooting a device.
The third one is named "Lock remote Keyboard and Mouse". When Remote Control a device now, there can be set a lock on the remote device. Then a user logged-on the device, cannot use his/her own keyboard and mouse during the remote session anymore.
Don't forget to configure the "Default Client Agent Settings", which is needed to have it all functional. Most settings are configured by default here. Only Permitted viewers must configured to users which receive the "Remote Control" rights. Other settings can be configured in this screen as well.
All functionality named here is very useful. So I will repeat my line from start: Remote Control functionality is much better in ConfigMgr 2012.

My research work centers around how to extract high level information about the user’s activities and his current situation utilizing sensors embedded into every day appliances. The inferred high level information (“context”) enables pro-active systems minimizing direct user interaction.
People increasingly use mobile computing technology to track their health and fitness progress, from simple step counting to monitoring food intake to measuring how long and well they sleep. Smartphone applications such as RunKeeper and Lose It! and wearable devices such as the Fitbit FLEX wristband foster better eating and exercise habits, decrease the risk of obesity-related diseases, and improve quality of life. Activity-tracking abilities are still hampered by the limited battery power of today’s mobile devices, but emerging technologies such as the M7 motion-sensing coprocessor in the new iPhone 5s make it easier to aggregate and interpret sensor data in a power-efficient manner. In addition, while most activity- recognition apps continue to focus on physical movement, such as steps taken or stairs climbed, new products such as Withings Pulse also quantify physiological signals such as heart rate.
Given these trends, it’s only a matter of time before we see mobile sensing technology applied to cognitive tasks, enabling novel forms of activity recognition. Most of my work focus on how we can use mobile sensing technology to improve learning, in particular how to track our reading habits.
Our everyday lives get more and more saturated with computing devices and embedded sensors. With access to powerful smart phones, sensors embedded into all types of intelligent objects and a ubiquitous Internet, large ensembles of users and devices may dynamically form, cooperate and interact with each other not bound to space or time. Given this rich crowd-sourced data and, most important, the appropriate aggregations, visualizations and user interfaces, the user could not only improve his own lifestyle, but the living conditions of a whole city or region leveraging sensor traces from smart phones, traffic, infrastructure etc. combined with other sources like social media data.
Today, with few exceptions, the state of the art approaches to context recognition assume dedicated sensing devices with fixed locations which are often carefully chosen to suit a particular application. This is a major limitation hindering wide-spread adoption of context recognition systems. In my phD. thesis, I presented a systematic evaluation of device placement effects in context recognition. In the course of my thesis, I developed methods, – to detect if a device is carried on the body or placed at a specific location in the environment (on a wooden table, in a closed metal compartment etc.), – to infer the coarse on-body location (on the wrist, on the torso, …) of a device, solely based on rotation and acceleration signals of the device) – to utilize heuristics that significantly increase the robustness of motion sensor-based activity recognition with respect to sensor displacement. – to detect the orientation of a device related to the user’s body.
All methods have been empirically evaluated in elaborate, realistic experimental setups or application scenarios. I try to pick application domains that provide a scientific challenge and have some broader social importance (e.g. from assistant living, over work process support to emergency response). A second theme in my research is the quantitative evaluation of the benefit pervasive context recognition systems bring to diverse applications. Up to now, I tackled the domain of wearable maintenance systems and activity logging systems for hospital documentation purposes. Working with real maintenance workers at the Carl Zeiss AG trying to support their everyday work, let me realize that although implementing context recognition systems is already difficult, the real challenge is the user interface aspect of pro-active pervasive systems. There is the high risk of performing unnecessary or unwanted actions leaving the user alienated.

As a business owner or an IT system administrator, it’s important to be able to identify rogue access points and minimize the threats that they pose to your wireless network. You’re probably wondering, “What are rogue access points?” Read on to find out how they can impact your wireless network and the steps you can take to improve your access point’s network management features so that they don’t become a recurrent issue.
What Are Rogue Access Points?
One of the most common security threats to enterprise networks, rogue access points (or rogue APs) are wireless access points that have been installed in an office or data center without the knowledge or permission from the system administrator via the wired infrastructure.
This allows unauthorized access to the secured network’s wired infrastructure, wherein any wireless user or client in the physical vicinity may bypass wireless security controls and monitor network traffic.
Some examples of a rogue AP include mobile devices attached via USB; wireless access points plugged directly to the existing firewall, switch, or router; or wireless devices connected to the server.
In most cases, these access points are set up by hackers as an attempt to illegally gather information or cause damage to your wireless network. Below are more details on the dangers of rogue APs.
1. Hackers Can Use Them to Install Malicious Software
If a rogue AP is created, hackers can use malicious software to gather sensitive data and personal information of employees located on the wireless network. This can lead to devastating level of identity theft and fraud. In some cases, the malware can even be designed to download itself onto the computers of people who connect to the corporate network, allowing the hackers to continue stealing data, even after they disconnect from the infected network.
2. Malware Can Also Damage Computers and Entire Networks
Malware that’s loaded onto your network from a rogue AP can also damage individual computers and even entire networks. This can be extremely costly for business owners, and it can severely slow down your business operations or even prevent them altogether.
3. Rogue APs Could Even Be Used to Disable Camera Systems
If malware is loaded onto a router via a rogue AP, it could be used to gain access to individual client devices that connect to the network, such as security systems. Malware that’s loaded on to your company’s client devices from a rogue access point can be used to gain remote access to computers, cameras, and anything else that connects to the internet in your company building.
4. Rogue APs Can Use Up Your Bandwidth
Rogue APs take a heavy toll bandwidth, which can result in exponential increases to your bill from your internet service provider. Not only can this cost your company money, but it can also slow down the internet connection for your employees. This can make it harder for your employees to do their work, which can also lead to lost revenue. And because rogue access points are often used for illicit activities, this can potentially cause far more serious legal troubles.
How Can You Prevent a Benign Access Point From Being Labeled Rogue?
A rogue AP is not authorized by the system administrator. Therefore, it’s important to make sure that you configure any intrusion detection system/prevention system (IDS/IPS) that you use to recognize existing wireless access points that you have cataloged. This will ensure that they are not incorrectly identified as rogue.
So, how do you know if an access point is authorized or not? Rogue APs can be detected by logging into your router as a system administrator. This will show you all of the access points on the network, and if you see something that has not been authorized, the access point is classified as rogue. A network security software program will do this for you, and you will be alerted if a rogue access point is created on your network.
How Can You Detect a Rogue AP?
If you are unsure whether an access point has been authorized or not, it’s important to investigate further, either with a wireless scanning tool or IDS/IPS. The signal strength from the rogue device will intensify as you get closer to it. Therefore, measuring the strength of the signal will allow you to determine where the rogue AP is located.
In many cases, you won’t even need any kind of special equipment to do it. All you’ll need is a laptop, which you will then hold at abdomen level. You will probably need to move around a bit to determine the direction that the signal is coming from.
Wi-Fi signals will be partially blocked if your back is turned to it. So, if you notice a dip in signal strength when you turn in a certain direction, you can turn around 180 degrees and find the direction that the signal is coming from. As you begin to approach the signal, it will continue to strengthen as you head closer to it until you locate the source. If you have access to equipment that can measure signal strength, locating the source becomes even easier.
What Are Rogue Clients?
Rogue clients refer to the individuals who are using your enterprise network without your consent. This does not necessarily mean that they have set up a rogue access point. Instead, it could simply be someone who has begun using your Wi-Fi from their laptop, smartphone, or other wireless devices without authorization.
In many cases, rogue clients are not using your WLAN for anything nefarious. However, unauthorized use of your Wi-Fi can cause serious problems even if a rogue access point has not been set up. So, how can you prevent rogue clients from accessing your network? These are few steps you can take to prevent a security hole being created in your network.
1. Pick the Right Passwords
In order to maintain a secure network, you’ll need to choose passwords that are difficult to guess. This will prevent someone from logging into your network without prior authorization to do so. Unfortunately, some business owners offer unchallenged access to their network by not setting a password. This can leave you extremely vulnerable to cyber attacks and security threats.
However, setting a strong password for Wi-Fi access is not enough on its own. You’ll need to make sure that you set a strong password for your router as well.
2. Monitor the Network for Unusual Activity
If you notice unusual activity on your network or more bandwidth is being used than usual, it’s possible that you could have a rogue client. If you notice any of these warning signs, check to see if there are any devices connected to your network that you do not recognize. You will be able to identify devices by their MAC address.
3. Have Excellent Cyber Security Practices
If you have good cyber security practices at your company, it’s less likely that a rogue client will be able to compromise your network. One of the most important steps to take is ensuring that rogue clients are detected quickly with a combination of scanning tools. Network security software, WiFi protection apps, and IDS/IPS will all alert you to rogue client logins.

The research center from Lithuania is looking for electronics companies who are interested in molded interconnect devices or electronics on glass surfaces. The center can offer new cost effective (comparing with state of the art) technology for circuit traces formation on both plastic and glass surface. The right partner is sought for a technical cooperation, research cooperation or license agreement.
The research center is carrying out a unique fundamental research and technological development works in scientific fields of laser technologies, optoelectronics, nuclear physics, organic chemistry, bio and nanotechnologies, electrochemical material science, functional materials, electronics, etc. in Lithuania. Fabrication of circuit traces is the most challenging task in moulded interconnect devices production, being both technically difficult to achieve and difficult to make cost effectively. Addressing this issue company has developed the selective surface activation induced by laser is a new technology for writing electronic circuits directly onto polymers by modifying surface p/roperties with a laser. Moulded interconnect devices – an injection-moulded thermoplastic part with integrated electronics – offers material, weight and cost savings by integrating electronic circuits directly into polymeric components. Lasers can write the circuits directly by modifying the surface of polymers followed by an electroless metal plating. Selective surface activation induced by laser is a three-step process: the first is surface modification by laser; second is chemical activation of modified areas; and the last step is metal deposition by electroless plating. The new technology offers laser writing speeds of up to 4m/s, and therefore spatial plating pitch is kept narrow at 25µm. The technology is focused on electronical application and can be applied to the automotive, medical, telecommunication industries and consumer products. The company offering this technology is looking for a research partners, who would like to collaborate on a project using this technology. Other type of agreements technology licensing or technocal assistance agreement would also be considered providing this would be a basis utilizing the technology and using companies expertise.
Innovations and advantages
Selective surface activation induced by laser offer cost effective plating method of polymers. Currently state of the art of Moulded interconnect devices traces production is Laser direct structuring technology, which is capable metalized only plastic with special dopants (additives) necessary for the plating process. These additives increase the price of the material at least 3 times. Selective surface activation induced by laser technology can be applied for standard plastics without any special additives. Thus, suggested technique reduces processing costs by at least three times compared with the current technology used in industry. The additives used in LDS technology is based on metal compounds. Metal based additives limit moulded interconnect devices application for radio frequency devices, thus selective surface activation induced by laser technology gains benefits in radio frequency applications. Another advantage of selective surface activation induced by laser technology against state of the art is that the mechanical properties of the plastic materials remain not affected by huge amount of special additives.

Here are some tips for how to get the most out of your digital hearing aid in different situations:
- In noisy environments: Look for a hearing aid with noise-canceling capabilities or directional microphones. These can help to reduce background noise and make it easier to focus on conversations.
- In windy conditions: Again, directional microphones can be helpful in reducing wind noise. You may also want to consider using an ear-level device rather than a behind-the-ear model, as this can further reduce wind noise.
- When using the phone: Many digital hearing aids now come with Bluetooth connectivity, which lets you stream phone calls directly to your hearing aid. This can be a great way to improve clarity and reduce background noise. Alternatively, you can use a phone clip-on accessory or a neck loop system.
- With music: Most digital hearing aids will automatically adjust the sound quality of music to make it sound natural and enjoyable. However, if you want to further customize the sound, look for a hearing aid with multiple listening programs or sound settings that you can adjust to your preference.
Things to take care of when you are a beginner:
- If you are new to hearing aids, there are a few things you should keep in mind. First, it may take some time to get used to the new sound of your own voice. This is perfectly normal and will improve with time.
- Second, be sure to have your hearing aid fitted by a professional to ensure that it is comfortable and properly adjusted for your hearing loss.
- Lastly, take the time to read the user manual and get familiar with all the features and functions of your hearing aid.
These days, one area of research is focused on developing hearing aids that can be controlled using a smartphone or other mobile device. This would allow users to easily adjust the settings to suit their individual needs.
Another area of research is focused on improving the quality of sound that hearing aids can reproduce. In particular, engineers are working on ways to reduce background noise so that users can better hear the people and sounds they want to focus on.

Wireless capabilities are an excellent asset for any system, and the router you are using offers powerful wireless features to keep your system connected. With Cisco Router, you can create a stable and secure wireless network that your users can rely on. It supports the latest wireless standards, and you can configure the router to use WPA or WPA2 encryption for your wireless network. The router also has several advanced features for managing your wireless network. You can configure the router to use different SSIDs for each band, allowing you to separate traffic on each bar and optimize the performance of each.
Cisco Router Will Offer Usage of Guest Network
You can also set up multiple access points with the router, extending your wireless coverage to areas of your home or office that may otherwise have trouble connecting. Cisco Router also offers an easy-to-use guest network feature, which provides limited access to visitors or guests. You can configure the guest network to provide internet access without giving full access to your leading network. This will allow your guests to connect without compromising your system’s security. Finally, the router offers a Wireless Bridge Mode, enabling you to use the router as a bridge between two networks. This is especially useful if you must bridge two networks with different security requirements.
Ensure Smooth Network Running with Cisco Router
Router provides an array of advanced features that can improve the reliability of your system. From the quality of service to parental control settings, Cisco Router offers the tools to ensure your network runs efficiently and securely. For example, if you need to connect two networks with varying authentication systems, you can use the router’s Bridge Mode to attach them securely. By taking advantage of these powerful wireless features, you can ensure that your system’s wireless connection remains solid and reliable. Whether connecting multiple access points or setting up a guest network, this router can help you keep your system connected easily.
Port Forwarding Will Maintain Cisco Router Performance
Port forwarding is a vital router feature, allowing you to control which applications and services can access your network. Cisco Router is beneficial if you have several devices connected to the same network and want to ensure they are securely connected. With port forwarding, you can forward ports from one device to another, preventing unauthorized access and keeping your network secure. Port forwarding is also an excellent tool for optimizing your network performance. It allows you to configure your router to send specific traffic on specific ports so your connection runs at its best speed. This means you can prioritize certain types of traffic, streaming video, over other less critical traffic types.
Juniper Router Will Reduce the Risk of Outsiders
Port forwarding is a great way to access remote services from within your network. For example, if you need to access a web server from the outside, you can set up port forwarding so that it routes traffic to the correct port on your server. Juniper Router ensures that only the accurate users have access and that no one else can gain access without permission. By forwarding ports to suitable destinations, you can limit who has access to your internal services. This reduces the risk of outsiders accessing your network and stealing sensitive data. Port forwarding is an essential feature of any router and should be used by anyone looking to maximize the performance and security of their network.
Allow Other Advanced Features within Juniper Router
Router offers many other advanced features that can improve the overall reliability of your system. First, it has advanced antenna technology to maximize signal strength and range. Juniper Router ensures your network is more reliable and efficient, reducing the risk of connection interruptions or dead spots. It also has an intuitive web-based user interface that makes setting up and managing your router easy. On the other hand, this eliminates the need for complicated setup procedures, which can be time-consuming and tedious. This can help keep your family safe online and protect young users from accessing inappropriate content.
Juniper Router Will Prioritize Streaming Services
Another great feature of this router is its ability to prioritize certain types of traffic for increased speed and efficiency. For example, you can prioritize streaming services or gaming traffic to ensure they have dedicated bandwidth, so you can get a better connection when playing online or streaming a movie. Juniper Router also supports Quality of Service for prioritizing certain types of traffic on your home network. You can prioritize VoIP calls, video streaming, or gaming traffic, ensuring these connections are fast and reliable. Finally, the router has advanced parental control settings, allowing you to block certain content from your network. Finally, it can help protect your network from malicious attacks.

Google Fiber has long held the spotlight over gigabit internet — nearly teasing Americans with its promise of unlimited access at unbelievable speeds. But Google isn’t the only company jumping on the gigabit bandwagon. All across the nation, individual companies are unveiling their own gigabit networks and giving the search giant a run for its money.
Not too long ago many of us wish we lived in Kansas City (as Google Fiber first unrolled its ultra-high speed internet there). Today, we can pick and choose. Omaha itself is being introduced to gigabit internet speeds through the services of Century Link. Other cities like Vancouver, Chicago, and Seattle are also building up their own networks. With all these high speed networks popping up faster than we can count, we at Omaha’s Elite Real Estate Group decided to breakdown the various internet services by company and city. You can view the results in our infographic below:

As per guidelines, the permissible noise levels in residential areas is 45 dB in night time and 55 dB in day time. Permissible noise limits in Silence zones are 50 dB in daytime (6am to 10 pm) and 40 dB in night time (10 pm to 6am). Silence zone is referred as areas up to 100 meters around such premises as hospitals, educational institutions and courts.
In the last three years, I have checked noise levels in CMEs organized by various bodies and found them to between 60 and 100 dB. For a proper attention span, the noise levels should be below 50 dB.
If a mike is used in a conference hall, the background noise level is more than 50 dB. Noise from other rooms, hallway noises, or noise within the hall itself such as conversation of the audience, noise from AC/fans, phones ringing, turning paper, etc. adds to the decibels. Background noise interferes with auditory communication and adversely affects speech perception and speech recognition. It also affects attention and memory.
One can tolerate exposure to 80 dB for up to 8 hours in a day; 85 dB for 4 hours; 90 dB for 2 hours; 95 dB for one hour; 100 dB for 30 minutes; 105 dB for 15 min and 110 dB for less than a minute without adequate sound protection.
People shout at each other in anger, but speak softly when expressing love. The distance remains the same, it’s the tone of the speech, which changes.
Exposure to noise beyond permissible levels is a health hazard. Noise shifts the body to sympathetic mode and takes us away from conscious-based decisions. Hence, we should make an effort to speak softly to minimize the ambient noise levels.
Vedic literature has described four gradations or levels of sound: Para (background noise of nature, no spoken sound), pashyanti (observed sound or perceived in mind), madhyama (audible sound), and vaikhari (articulated sound or spoken words). We should speak in Pashyanti and madhyama.
A national workshop Noise and Health was organized on Sunday at Hotel Le Meridian for Safe Sound initiative of IMA as part of the National Initiative for Safe Sound (NISS). The workshop was inaugurated by IMA National President Dr Ravi Wankhedkar. Dr John Panicker was the National Co-ordinator. Through this initiative, IMA has entrusted itself with the responsibility of achieving noise pollution free India.
According to new estimates released by WHO on the occasion of World Hearing Day on March 3, around 900 million people could suffer from disabling hearing loss by 2050. Exposure to loud sounds through personal audio devices and in entertainment venues and workplaces is a major factor contributing to the rising prevalence of hearing loss.
All of us are now used to mikes in class rooms or lecture halls or DJ music.
Instead, ask the audience “Am I audible?” If you are audible without mike, then don’t use a mike. When I spoke in the IMA NISS workshop, I did so without using a mike.
