For each an optical and vibrating alert warns when thresholds have been reached. The LED warning lamp of the Noise Dose Alert changes from green to amber when you reach 80% of your limit to noise exposure and changes to red at 100% when you should put on ear defenders or remove yourself from the environment. For the Noise Level Alert the LED warning lamp changes to amber when noise levels reach 85dB and red at 85dB when again you should put on ear defenders or remove yourself from the environment.

Both new Listen Ear™ products include the Pambry Electronics patented anti-knock feature (Patent No: GB 2 551 724) and have a long battery life.

Nigel Bicknell, Director at Pambry Electronics said “These two new Personal Noise ‘Alert’ products will provide a good entry level health and safety solution for our customers looking to buy a noise alert meter for themselves or for their employees”.

A quintessential sound of the British countryside or an irritating source of noise pollution? The answer it seems, lies in the ears of the listener.

When a local council received a complaint that the local bell ringers were becoming a nuisance, they needed to reassure local residents that noise levels hadn’t increased significantly and definitely weren’t a threat to health.

Whilst there had been a church on the site for over 800 years and the residents must have known it was there when they bought the house, the council recognised that they did have a point when claiming that nobody had ever checked that the noise from the bells wasn’t harmful.

When they started to research noise damage, it became clear that much more is now understood about the long term, cumulative, damage possible from noise exposure and that it is an issue that needs to be taken seriously. Even if the noise has been part of our environment for centuries.

A sound survey was the first proposed solution but, with initial estimates coming in at £2000 – £3000 for a one-off survey, was going to be prohibitively expensive. Especially if it needed repeating several times.

After researching the market for different options, it was decided that the simplest, and most cost effective, solution was to treat the residents as “workers” and measure their “daily dose” of noise. This would not only provide a measure of the actual noise level the residents were exposed to but also include any other possible noise sources. As damage to health from noise is known to be cumulative, other noise sources needed to be taken into account as well.

The noise “Dosimeter” selected was Listen Ear™ from Pambry Electronics. This is a simple, wearable device that costs less than £300 and has the huge advantage of a 4 week battery life. Using Listen Ear™ it was possible to simply charge the unit and set it to log noise measurements then give it to local residents to wear for a few days. The display on the meter shows instantaneous noise levels and % of a safe daily dose with warning lights if there is a risk of harm. If desired the resident can be given a simple, free, App to monitor their noise exposure on a tablet or phone.

Listen Ear™ App Screens

Once the Listen Ear™ has been recovered it’s a simple matter to check the actual noise dose measured and download a detailed log file for archiving or detailed analysis.

This “self-survey” approach has the additional benefit of reassuring the residents that the survey really does represent the noise they are exposed to.

For less than the cost of an initial survey, the local council have shown that the bell noise really isn’t a threat to hearing health and they know have a simple tool to measure possible noise problems anywhere else in the community.

Exposure to loud noise in the workplace for long periods of time can have serious health implications on your hearing, but you may not know that this prolonged exposure can also have an affect on mental and physical health too?

A noisy workplace environment of around 85 decibels (dBA) where you must raise your voice to be heard by someone three feet away can damage your hearing after repeated exposures of eight hours or more.

At 95 dBA or more where you need to shout to be heard by someone at arm’s length – your hearing can be put at risk in less than an hour. Heavy plant machinery, chain saws, and other such equipment used in manufacturing, fabrication, welding and construction industries all operate around 95 dBA.

Here are some other factors to consider if you work in a noisy environment.

Stress and high blood pressure

In addition to damaging hearing, loud noise can cause other physical and psychological conditions including stress. Often the short-term effects of noise related stress go unnoticed or are blamed on other things.

Loud noise can influence the cardiovascular system, resulting in an increase in blood pressure and the release of catecholamines in the blood. An increased level of catecholamines in the blood is associated with stress.

Effect on pregnancy

Research suggests that an unborn child exposed to prolonged loud noise levels may influence the hearing of the child in later life with low frequencies having a greater potential for causing harm.

Accidents and injuries    

Other impacts of prolonged noise exposure on the health of a worker include reduced communication and concentration and a contribution to workplace accidents and injuries with difficulty in hearing warning signals.

However, noise exposure in the workplace can be reduced and occupational hearing loss entirely prevented with today’s hearing loss prevention strategies and technology such as Pambry Electronics Listen Ear™ – Personal Noise Dose Meter.

In summary it is very important for employers to carry out regular occupational health assessments for their workers with checks for symptoms over exposure to loud noise such as hearing loss and increased blood pressure.

Workers in the Construction Industry are surrounded by high-noise levels from heavy equipment.

Hearing Loss Facts

Research has shown that long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. The louder the sound, the shorter the amount of time it takes for noise induced hearing loss to occur.

Construction Site Hearing Loss and Health & Safety

  • Workers with hearing loss can potentially miss audible warning signals.
  • Hearing loss may lead to a breakdown in communication.
  • Increased effort to listen by hearing impaired workers may lead to fatigue, anxiety, and stress.
  • Workers may also suffer from tinnitus, causing them to hear ringing, rushing, or other noises even when there are no surrounding sounds

How to Protect Hearing and Prevent Noise Induced Hearing Loss

Noise induced hearing loss among construction site workers is preventable. Some important measures that can be taken include:

  • Wearing hearing protective devices such as earplugs, earmuffs or headsets and selecting the right device for your working environment is important.
  • Ensure you are wearing a hearing protective device that meets the proper SNR for the sound level measured in your work environment.
  • Choose a hearing protection solution that is unobtrusive and doesn’t restrict workers, like the Pambry Electronics Listen Ear™ – Personal Noise Dose Meter, so they will always keep it on in all high noise work environments.

UK based Pambry Electronics Ltd of Poole in Dorset have recently launched their new Personal Noise Dose Meter. It is believed to be the lowest priced Class 2 Noise Dose PME (personal monitoring equipment) in the world and is typically 30% to 50% of its nearest rival.

Expected markets are Health and Safety in, Construction, Mining, Manufacturing, Test Engineering, Club and Concert staff plus many others.

With a footprint smaller than a credit card and just 15mm thick (not including the clothing clip), the device has been designed on the back of years of Pambry Electronics’ military experience in microphones and electronics, and such issues as periodic calibration has been extended to more than a year. Also the environmental conditions in which the device can be used are much tougher.

The device part number PED 0828 (shown above with its optionally available external microphone) is unique as it not only includes all the usual features of its rivals’ product such as measurement of Noise Dose (8hr day), Noise Level, Data logging and download, etc but has inbuilt capability to monitor Ambient Temperature, Relative Humidity, Motion and Orientation.

A key new feature is the addition of device knock and vibration detection. This feature vastly improves the accuracy of the noise dose results and is subject to a PCT patent application.

The device comes in three standard colours, cream, grey or black. Special colours can be ordered subject to quantity.

Extracting the data recordings (datalog files) can either be via microUSB cable or mobile application connectivity to your smart phone or PC. The cable connection is also used to recharge the device from any PC USB port or charger.

The battery life between charges is in excess of 4 working weeks and the device meets the criteria of the Control of Noise at Work Regulations 2005 (UK) and international standards IEC 61672-1 and IEC 61252.

It is expected the device will appeal not just to the usual corporate users anxious to protect their employees but also individuals wishing to know if their hearing is under threat as the price is well within the reach of most individuals. The device can accommodate the use of earmuffs by selecting from the built in database or keying in the specified earmuff SNR value.

The external microphone is recommended for use when the weather conditions are poor and the user would prefer to place the main device somewhere like a coat pocket

The display is lit to allow ease of use in poorly illuminated situations, and displays selectable pages of information such current and projected Noise Dose, current and max Noise Level, graphical presentation of Noise level history (last 2hrs), current/min and max Temperature and Relative Humidity, Battery charge status, Noise data detail to current time, and further sub level settings pages to allow selection of the more complex features of the device.

There is also a warning light that flashes Amber when the Noise dose has reached 70% (of the safe level for 8hr day) and Red when 90% has been reached. It will also flash Blue when peak safe noise level of 120dBC has been exceeded. All level thresholds and weightings can be changed in these settings page too.

The data log recording files can be used to provide some clever analysis since all measurements including temperature, humidity, knock count, motion, etc are available against the built in real time clock.
