The hearing of employees exposed to noise can be monitored through regular audiometric examinations. Such testing in itself is not a preventive mechanism, and is only relevant in the context of a comprehensive Hearing Conservation Program (HCP). Any changes in hearing levels over time revealed by audiometry shall be thoroughly investigated as to their cause(s) and the need for corrective action.
An audiometric testing program shall be conducted to any employee exposed to Noise Exposure Limit (NEL). The employer shall conduct audiometric tests at no cost to the employees.
