NOISE ASSESSMENTS | HOW OFTEN SHOULD A NOISE SURVEY BE CARRIED OUT?
A question we get asked over and over again is “How often should noise assessments and noise surveys be carried out?”
Unfortunately, there is no clear cut answer listed in regulation.
Do You Require Updated Noise Assessments?
So why would a noise survey no longer be valid and when should previous noise assessments be reviewed?
* The process is changed in any way.
* Installation of new machines, and removal of old machines.
* Noise control measures have become reasonably practicable.
* You change the shifts an operator works (i.e. you go from 8hrs to 12hrs).
* Noise controls have been installed (and you want to see if things have improved).
* Your Audiometry Testing has shown a significant deterioration in employee’s hearing levels.
* You become aware of new ways of working or controlling noises (e.g. as written in trade journals).
In answer to the question, there is no set frequency for noise assessments; however a regular noise survey helps determine if there is any deterioration in machinery that may be causing increases in noise level. Therefore we recommend that noise levels are carried out and reviewed at least every two years.
