Exposure to noise in excess of the limits can lead to hearing loss. Therefore, where a Noise Risk Assessment report indicates that the employee is exposed to excessive noise exceeding the limit specified by the regulation, the employer shall engage a DOSH approved Audiometric Testing Centre to conduct the Audiometry.

An Audiometry is the testing of employees’ ability to hear sounds at different frequencies. The test is conducted by a trained technician using an electronic equipment known as an audiometer.

The purpose of audiometry for employees is to help determine if he/she is at risk of having occupational hearing loss. In addition, audiometry also helps determine whether noise control measures being implemented are effective in preventing occupational hearing loss.
