Audiometry

Many people will have undergone audiometry to measure their hearing ability at some point in their life, most likely while at school and the basic principles of audiometry used as screening in the workplace are pretty much the same, except we don't give out lollipops afterwards. Via multiple purpose-built mobile units or by conducting the testing in a quiet room depending on the client's wishes, HSMC offer high quality workplace screening audiometry to help employers achieve compliance with the Control of Noise at Work Regulations 2005. We offer 24 hour availability, working whatever shift patterns are needed to fit in with your employees, including nights and weekends.

Audiometry became more critical with the 2005 update to the noise regulations which require anyone exposed to noise levels of 85dB(A) or more to be provided with 'health surveillance', which is a slightly Orwellian way of saying 'audiometry'.

The audiometry process requires attendees to wear a set of headphones through which a series sounds at differing pitches and volumes are played. They indicate whether they can hear the sound or not allowing the technician conducting the test to identify any loss in hearing. HSMC will undertake this for you, providing a practical, plain-English detailed employer's report.

Audiometry components

Each audiometry appointment takes approximately 15 minutes, completed with modern fully calibrated audiometers and if in one of the mobile units, a noise-reducing audiometry booth and noise-reducing headphones to give the maximum sound reduction. See the Audiometry Routine section for detail on what the testing process involves.

Audiometry reports

We supply detailed screening audiometry reports with every job giving the client everything they need to manage the issue and comply with the Noise Regs. The Audiometry Reports page gives pretty extensive detail on what it is you get for you hard earned money, but the shortened version is:

  • A plain English explanation of what it all means
  • A summary section saying who scored which category of result, using the HSE's classifications for workplace audiometry.
  • Additional detail on specific cases - all referred individuals and all Category 3 or 4 cases.
  • A second section giving a complete copy of the audiogram (the actual results) for each person.

All HSMC audiometry technicians have completed courses on industrial audiometry approved by the British Society of Audiology in the UK. In addition to this our head honcho, spotting an opportunity for some expenses-based fecklessness, also obtained audiometry qualifications in the USA. He is also a member of the British Society of Audiology and oversees all HSMC audiometry and produces or approves all completed employer's reports. We also have our own in-house ongoing audiometry refresher training.

The light relief

A man goes into his doctor and says ", Doctor, I'm having problems with my hearing"
The Doctor replies, "OK, can you tell me about the symptoms"
"Sure" says the man, "Homer is fat and yellow, Marge has big hair..."
