Audiometric health surveillance should be provided for workers who are regularly exposed to noise levels above the upper exposure values (85 db). Between the lower and upper value exposure value levels (80-85 db) audiometry should also be done for people who are sensitive to noise induced hearing loss, It should be performed as a baseline at pre-employment, then annually for 2 years.
Audiometry is an established screening technique which detects early damage to hearing possibly resulting from exposure to noise, the outcome data can be used to review the existing control measures. Audiometry tests are performed to provide a baseline, assess an employee’s hearing ability in relation to their work and at routine intervals, which will depend on the outcome of the results when tested.
