The term “noise exposure monitoring” typically means the measurement of employee noise exposure levels and workplace sound level. This monitoring is part of the workplace hearing conservation programme. Noise hazards can cause many health effects such as hearing impairment, hypertension, sleep disturbance and increased workplace accidents.
Why it is Needed?
Where there is uncertainty of the risk of the noise exposed to the employee at the workplace. This is to ensure that employee noise exposures are within permissible limits. According to Factories and Machinery (Noise Exposure) Regulations 1989, employers are required to determine if employees are exposed to excessive noise in the workplace.
How to conduct?
This monitoring is conducted by ‘Noise Competent Personnel’ according to Factories & Machinery Act, 1967, (Noise Exposure Regulations, 1989). Scope of the monitoring will be area monitoring and personal exposure monitoring. Area monitoring is conducted using pre-calibrated sound level meter by identifying the noise source and the noise level of the area. Personal exposure monitoring is conducted using pre-calibrated noise dosimeter to gauge the noise exposure level of a particular employee during the working period. The employee should continue to work in the normal operating manner while wearing the dosimeter.
