Occupational Noise

Occupational noise is a Calibrated measurement of workplace noise.

In the workplace, exposure to noise is covered by the Safety, Health and Welfare at Work (General Application) Regulations 2007.  

Do you need an Occupational Noise Assessment completed for your company?

  • Have you added new machinery to your workplace?
  • Has it been more than two years since your last assessment?
  • Do you work in a noisy industry, eg construction, processing, engineering etc
  • Are you familiar with the new regulations?

Assessment Process

One of our Consultants will visit your premises to measure noise levels using a sound level meter. Measurements will be taken at several different locations, concentrating on operator positions to determine the actual exposure levels of the workers.

Noise dosimeters can also be arranged for areas where noise levels are highly variable.

Noise Exposure Limits

Noise is measured in decibels (dB). The Noise Regulations require you to take specific action at certain action values. These relate to

  1. the levels of your employees exposure to noise averaged over a working day or week; and
  2. the maximum noise (peak sound pressure) to which employees are exposed in a working day.

The values are:

  • Lower Exposure Action Values (EAVlwr):
    • daily or weekly exposure of 80 dB(A);
    • peak sound pressure of 135 dB(C);
  • Upper Exposure Action Values (EAVupr):
    • daily or weekly exposure of 85 dB(A);
    • peak sound pressure of 137 dB(C).

Levels of noise exposure which must not be exceeded:

  • Exposure Limit Values (ELV):
    • daily or weekly exposure of 87 dB(A);
    • peak sound pressure of 140 dB(C).

The different exposure values collected will allow us to determine suitable hearing protection for your employees.


You will be issued with a detailed assessment report which will provide the results of the monitoring and observations made during the visit.

The workers exposure will be compared to the action values and limit values given in the regulations.

Work locations, or specific tasks, that will require the use of hearing protection will be identified. Practical recommendations on how to reduce the noise levels will also be included in the report.

The Report will aid in demonstrating that you, as an employer, have fulfilled your obligation under Health & Safety Law to do 'all that is reasonably practicable' to create and maintain a safe workplace for you and your employees.
