What is the legal noise limit for workplaces in Malaysia?

Under the Noise Exposure Regulations 2019, 'excessive noise' is defined as exceeding 82 dB(A) daily exposure. The Noise Exposure Limit (NEL) — the legal maximum — is 85 dB(A). Employers must ensure no worker is exposed above 85 dB(A).

Do I need a registered Noise Risk Assessor (NRA)?

Yes. If your workplace may expose employees to noise exceeding 82 dB(A), you must appoint a Noise Risk Assessor registered with the Director General of DOSH. The NRA must use IEC-compliant equipment and submit a report within one month.

How often must noise risk assessments be repeated?

Employers must re-identify excessive noise not more than one year after the previous identification. Full noise risk assessments must be reviewed not more than five years from the previous assessment, or when directed by the Director General.

What is a Hearing Conservation Programme (HCP)?

An HCP is a comprehensive system to prevent occupational noise-related hearing disorders. It includes noise monitoring, engineering controls, administrative controls, provision of personal hearing protectors, audiometric testing, and employee training.

Noise Exposure Assessment & Hearing Conservation

DOSH-aligned workplace noise mapping, audiometric testing coordination, and hearing conservation programme design under the Noise Exposure Regulations 2019 [P.U. (A) 60/2019].

Noise Exposure Regulations 2019

The OSH (Noise Exposure) Regulations 2019 [P.U.(A) 60/2019], in force 1 June 2019, replaced the 1989 regulations. Noise above 82 dB(A) is 'excessive noise' and needs a DOSH-registered Noise Risk Assessor; the exposure limit is 85 dB(A).

> 82 dB(A)

Above 82 dB(A): a DOSH-registered Noise Risk Assessor must assess the workplace (reg 4). Above the exposure limit of 85 dB(A) (or 115 dB(A) maximum / 140 dB(C) peak): annual audiometric testing at a DOSH-approved centre (reg 9). Employees exposed to excessive noise need training at least once a year (reg 5(2)). The Hearing Conservation Programme is set out in the 2019 Code of Practice (s.5).

> 85 dB(A)

Noise Exposure Limit (NEL). Must not be exceeded. Requires engineering controls, administrative controls, and mandatory annual audiometric testing.

> 115 dB(A)

Maximum sound pressure level at any time. Immediate hearing protection zone designation and strict control measures required.

> 140 dB(C)

Peak sound pressure level limit. Exposure at this level can cause instantaneous acoustic trauma and permanent hearing damage.
