Commercial Screening

Noise protection in the workplace

Are you aware that by law Employers must prevent or reduce risks to health and safety from exposure to noise at work?

The Control of Noise at Work Regulations 2005 – set out by the HSE (Health and Safety Executive)

The Regulations require an employer to:

_ assess the risks to your employees from noise at work;

_ take action to reduce the noise exposure that produces those risks;

_ provide your employees with hearing protection;

_ make sure the legal limits on noise exposure are not exceeded;

_ provide your employees with information, instruction and training;

_ carry out health surveillance where there is a risk to health.

In the United Kingdom noise induced hearing loss leads to an average injury claim of £18,000 per employee, a figure that could be easily avoided through professional assessment, appropriate protection and the correct advice.

Is your workforce subject to loud noise?

Spend a day at the place of work then answer the following questions, if you can answer ‘yes’ to any, then you should probably be taking action...

1. Is the noise intrusive – like a busy street, a vacuum cleaner or a crowded restaurant – for most of the working day?

2. Do you have to raise your voice to have a normal conversation when about 2 metres apart for at least part of the day?

3. Are noisy powered machinery or intense sound systems used for over half an hour a day?

4. Did the day leave you with muffled hearing, even if it is better by the next morning?

What action should you take?

Once you have assessed the workplace and concluded that the environment is ‘too loud’, you should contact a qualified, registered Hearing Audiologist who offers ‘Commercial Hearing Screening’. The audiologist should then be able to visit your place of work with an ambiance noise meter and assess the need for noise reduction. If the environment falls under the legislated noise level thresholds, the audiologist can then offer means of protecting your staff, as well as an initial hearing screening, and follow-up annual hearing tests to monitor the efficiency of that protection.

What costs are involved?

Commercial Hearing Screening charges vary from audiologist to audiologist, and depend on the size of your workforce, but most fall in the region of £20 to £40 per person. A wide range of hearing protection products are available, from basic earplugs to electronic filters, and each offer varying levels of protection. This is why the advice of an audiologist is invaluable in helping you select the product that provides the right kind of protection. Prices for hearing protection products can start from as little as £5.

Hearing loss is a dangerous thing when communication is so important.

Even Unconsciously, Sound Helps Us See

"Imagine you are playing ping-pong with a friend. Your friend makes a serve. Information about where and when the ball hit the table is provided by both vision and hearing. Scientists have believed that each of the senses produces an estimate relevant for the task (in this example, about the location or time of the ball's impact) and then these votes get combined subconsciously according to rules that take into account which sense is more reliable. And this is how the senses interact in how we perceive the world.

However findings show that the senses of hearing and vision can also interact at a more basic level, before they each even produce an estimate," says Ladan Shams, a UCLA professor of psychology, and the senior author of a new study appearing in the December issue of Psychological Science, a journal published by the Association for Psychological Science. "If we think of the perceptual system as a democracy where each sense is like a person casting a vote and all votes are counted (albeit with different weights) to reach a decision, what our study shows is that the voters talk to one another and influence one another even before each casts a vote."

"The senses affect each other in many ways," says cognitive neuroscientist Robyn Kim. There are connections between the auditory and visual portions of the brain and at the cognitive level. When the information from one sense is ambiguous, another sense can step in and clarify or ratify the perception. Now, for the first time, Kim, Megan Peters, and Ladan Shams, working at the University of California Los Angeles, have shown behavioral evidence that this interplay happens in the earliest workings of perception -- not just before that logical decision-making stage, but before the pre-conscious combination of sensory information.

To demonstrate that one sense can affect another even before perception, the researchers showed 63 participants a bunch of dots on a screen, in two phases with a pause between them. In one phase, the dots moved around at random; in the other, some proportion moved together from right to left. The participants had to indicate in which phase the dots moved together horizontally. In experiment 1, the subjects were divided into three groups. While they looked at the dots, one group heard sound moving in the same direction as the right-to-left dots, and stationary sound in the random phase. A second group heard the same right-to-left sound in both phases. The third group heard the identical sound in both phases, but it moved in the opposite direction of the dots. In the second and third conditions, because the sound was exactly the same in both phases, it added no cognitively useful information about which phase had the leftward-moving dots. In experiment 2, each participant experienced trials in all three conditions.

The results: All did best under the first condition -- when the sound moved only in the leftward-motion phase. The opposite-moving sound neither enhanced nor worsened the visual perception. But surprisingly, the uninformative sound -- the one that traveled leftward both with the leftward-moving dots and also when the dots moved randomly -- helped people correctly perceive when the dots were moving from one side to the other. Hearing enhanced seeing, even though the added sense couldn't help them make the choice.

The study, says Kim, should add to our appreciation of the complexity of our senses. "Most of us understand that smell affects taste. But people tend to think that what they see is what they see and what they hear is what they hear." The findings of this study offer "further evidence that, even at a non-conscious level, visual and auditory processes are not so straightforward," she says. "Perception is actually a very complex thing affected by many factors."

"This study shows that at least in regards to perception of moving objects, hearing and sight are deeply intertwined, to the degree that even when sound is completely irrelevant to the task, it still influences the way we see the world," Shams says.
