WHAT IS AUDIOMETRIC TESTING?
Audiometric testing is mandatory for all UK employees who are exposed to levels of 85dB(A) on a daily basis. It checks the effectiveness of the noise control measures a company has in place and assesses whether or not the staff require regular hearing tests as a result.
It is easy to safeguard your employees against losing their hearing as a result of noise at work. An audiometric test, or hearing test, is non-obtrusive and only takes around 15 minutes. Hearing tests can either be conducted in a quiet room on site or in our purpose built mobile unit which can be parked within the grounds of your premises, providing it is within reach of a power supply
The employee's ears are inspected using an otoscope to make sure that there is no excess wax present, which can cause inaccurate results. We also use digital imaging to assist. The employee then listens to a series of beeps at varying volumes and frequency. When the beep is audible, the employee pushes a hand-held button. It’s that simple.
We then analyse the results and create an audiogram – this is a graph showing the employees hearing threshold. We calculate whether the employee has a hearing level that is typical of a person of their age, of whether there is any sign of hearing loss. If it is suspected that there is hearing loss, the employee is referred to a specialist for further investigation.
This test is then repeated annually for the first two years, then once every three years thereafter providing that no deterioration is found. If an employee does show signs of hearing loss we will recommend a scheme of noise protection and then re-test the employee every year until there is no further deterioration.

Workplace Noise Assessment
When a workplace noise assessment is required a thorough survey of all work areas is undertaken, allowing for us to build a picture of which areas of a workplace create particularly high levels of noise. This is done in two ways – using a hand held sound level meter and also using DoseBadges which are small lightweight microphones which clip onto employees clothing and monitor their complete noise exposure for the desired time.
