Noun phrase

Countable

The higher of the two levels of daily or weekly personal noise exposure or of peak sound pressure which, if reached or exceeded, require specified action to be taken to reduce risk.
The upper exposure action values are
(a) a daily or weekly personal noise exposure of 85 dB (A-weighted);
(b) a peak sound pressure of 137 dB (C-weighted).

If any employee is likely to be exposed to noise at or above an upper exposure action value, the employer shall reduce exposure to as low a level as is reasonably practicable by establishing and implementing a programme of organisational and technical measures, excluding the provision of personal hearing protectors, which is appropriate to the activity.
If an employer is unable by other means to reduce the levels of noise to which an employee is likely to be exposed to below an upper exposure action value, he shall provide personal hearing protectors to any employee who is so exposed.
