Acoustic booth

A loss control measure against identified risks by segregating the identified hazard to a specific (remote) location to protect the surrounding area from its effects and vice versa. Examples include placement of a chemical plant or process in a remote location and enclosure of an individual in an acoustic booth or enclosure to protect against noise exposure.

Acoustic cabins and booths for machine operators or supervisors. Such enclosures should achieve a sound level reduction of between 20 and 30dB and be adequately ventilated air conditioning may also be necessary. They are often of demountable construction, so that they can conveniently be removed and reassembled where and when required. Suppliers of acoustic cabins, etc. are listed in the publication LSI 01-200 (1977).

Isolation of workers in acoustically-quiet booths or control areas properly enclosed, coupled with scheduling of work periods to reduce dose. This will only be effective where there is little or no need for constant movement into or out of areas with high noise levels even a short duration exposure to high sound pressure levels will exceed the permitted daily dose. Nevertheless, improved design of vehicle and plant cabs and (for example) batch plant and lifting equipment operating positions can do much to improve the health of operators.
