Audiometry

Noise induced hearing is loss is usually permanent and cannot be reversed. This is the reason why hearing checks at work are carried out at regular periodic intervals so that slight changes in your hearing can be detected at a stage where action can be taken to prevent lasting damage. Exposure to loud noise can also lead to tinnitus (ringing in your ears) which can be temporary or become permanent. Exposure to loud noise may also affect your performance, communication and interfere with audibility of safety/warning signals. The sound frequencies most commonly damaged are those that you rely on every day e.g. during conversation with family or friends. It is important that if you do work in a noisy environment that you comply with all safety measures that are in place e.g. wearing hearing protection where provided.

General health effects of noise on hearing

The Control of Noise at Work Regulations 2005 

In the first instance speak to your line manager. They will make the assessment of whether a hearing conservation programme which includes hearing checks is indicated for you. Your line manager should directly refer you to OHS via the Request for Health Surveillance form. You will then receive notification of the details of your appointment. 

If you are called for a hearing check (audiometry) you should submit your completed Noise and Audiometric surveillance questionnaire electronically prior to your appointment. It would be helpful if you could bring: 

• Your hearing protection devices e.g. ear plugs, muffs. This will allow the OHS personnel  to ensure that you are wearing them correctly and they can also give general advice on how to care for them. It is also an opportunity to assess whether they are the most appropriate devices for you (if appropriate). 

• A list of any medication that you are currently taking. 

Remember to avoid loud noise for several hours prior to your hearing check and if you cannot do this please ensure that you wear your hearing protection. Exposure to loud noise can cause a temporary reduction in your hearing so your results may not be an accurate and true reflection of your hearing. You may then require another appointment. 

Yes, but in the first instance we would advise that you try and discuss, and resolve, the issue with your line manager. However if you feel your health is being affected by work you can either: 

Self- refer to the OHS and someone will contact you directly :Self-referral to Occupational Health 

or complete an ill health report if you feel your health is being affected by work. Please note that this method will require a direct notification to the Health and Safety Department for further specialist input e.g. occupational hygienist, bio-safety advisor, radiation protection advisor etc.: Occupational Ill Health reporting
