Am I over the noise exposure action values?
A day’s noise exposure (L_EP,d) from each job’s level and time, against the Noise at Work Regulations 2005 action and limit values.
Questions people ask
What are the noise action and limit values?
The Control of Noise at Work Regulations 2005, regulation 4: the lower exposure action values are a daily or weekly exposure of 80 dB(A) and a peak of 135 dB(C); the upper, 85 dB(A) and 137 dB(C); the exposure limit values, 87 dB(A) and 140 dB(C).
How is a day’s exposure worked out?
As Schedule 1 of the Regulations sets out: each job’s level and time are added on an energy basis over an 8-hour day. 4 hours at 88 dB(A) comes to about 85 dB(A) - halving the time takes off 3 dB. The page shows one figure, to a tenth of a decibel, and reads the line from that figure.
Does hearing protection count?
For the exposure limit values, yes - regulation 4(5) takes the protection the employer provides into account. For the two action values, no. The figure on this page is before protection.
Is this a noise assessment?
No. It is a starting point for where a day sits. The assessment, and what to do about it, is for a competent person. Pascoe Business Systems makes no compliance claim.

Need the paperwork behind this, not just the number? PBS Policies produces branded risk assessments, toolbox talks and handbooks from a starter library, with your business substituted throughout.
Read before you rely on this. These compliance tools are a starting point, not a decision. The exposure figures, the notification answer, the risk score and the accreditation list are guidance only — none of them is a risk assessment, a HAV or noise exposure assessment, legal advice or a compliance sign-off, and Pascoe Business Systems makes no compliance claim. Current HSE guidance and a competent person decide.
