Safety and Health Topics | Occupational Noise Exposure ...

Noise is measured in units of sound pressure levels called decibels, named after Alexander Graham Bell, using A-weighted sound levels (dBA). The A-weighted sound levels closely match the perception of loudness by the human ear. Decibels are measured on a logarithmic scale which means that a small change in the number of decibels results in a huge change in the amount of noise and the potential ...

The Noise at Work Regulations 2005, University Safety Office

The damaging effects of noise are related to the ‘dose’ that the ear receives and this depends on the duration of the exposure and the noise level. Equal doses will cause the same amount of damage. Therefore short exposure to high levels of noise will cause similar damage to lower levels of noise exposure that are of longer duration.
