Hearing testing and it's Importance not to be underrated


Hearing tests are required in B.C. for workers exposed to noise greater than 85 dBA Lex for eight hours, or its equivalent, a noise dose of one Pascal-squared hour (Pa2h).

Hearing tests are vital because they identify the beginning of noise-induced hearing loss long before workers notice it. As part of the test, workers are individually counseled about the results, the follow-up required, and when a repeat test will occur. Workers are also counseled about the type of hearing protection to use.

Hearing tests must be conducted annually to effectively monitor the hearing of noise-exposed workers. The hearing test, including counseling, takes approximately 15 to 20 minutes.

During a hearing test, a worker is seated in a soundproof booth with a window and a set of earphones are placed over the ears. When the worker is ready, the audiometric technician sends a series of tones through the earphones to one ear, and then the other. The worker signals the technician as the tones are heard. The workers’ responses are recorded for each ear and the results are graphed on a chart called an audiogram.
