Workplace Noise Risk Assessments
What are the Noise at Work Regulations Noise Criteria and Action Values?
The Control of Noise at Work criteria is based on daily or weekly noise exposure levels the acoustic parameter for noise is LEP,d. Once the exposure of an employee has been calculated or measured it should then be compared to the action values and limit values outlined in the Control of Noise at Work Regulations 2005. These are as follows:
The lower exposure action values (LEAV) are:
- A daily or weekly personal noise exposure of 80 dB (A-weighted); and
- A peak sound pressure of 135 dB (C-weighted).
The upper exposure action values (UEAV) are:
- A daily or weekly personal noise exposure of 85 dB (A-weighted); and
- A peak sound pressure of 137 dB (C-weighted).
The exposure limit values (ELV) are:
- A daily or weekly personal noise exposure of 87 dB (A-weighted); and
- A peak sound pressure of 140 dB (C-weighted)
