Area Noise Mapping & Initial Employee Noise Exposure Monitoring

Under the First Schedule of the Factories and Machinery (Noise Exposure) Regulations 1989, the Department of Occupational Safety and Health (DOSH) requires operators of all factories in which persons are employed in any occupation involving exposure to excessive noise level in the workplace, to conduct initial area noise mapping and employee exposure monitoring within six months from the date when these regulations take effect (Reg.(9)).

It is also required that noise mapping and employee exposure monitoring works be carried out by a competent person using approved noise measuring instrument (Reg (14)).

For the purpose of conducting and preparing this report, a noise competent person, registered with the DOSH must be appointed to conduct a noise monitoring program using approved noise measuring equipment (Reg 14).

The roles of the noise assessor in this respect are:

  • to provide expert knowledge regarding identifying high noise work areas and the likely levels of exposure by employees to levels exceeding the permissible exposure limit; and
  • to recommend necessary actions for further noise reduction to ensure compliance with the limits prescribed in Regulations 5 of the Factories and Machinery (Noise Exposure) Regulations 1989, which are based on mandatory requirement and other sound control practices as laid out by the DOSH.
