Noise Risk Assessment & Audiometric Testing in Johor Bahru
Compliance with the Noise Exposure Regulations 2019 — assessment by a DOSH-registered noise risk assessor, audiometric testing through a registered centre, and a hearing conservation programme that holds.
The limits dropped in 2019
The Occupational Safety and Health (Noise Exposure) Regulations 2019 replaced the Factories and Machinery (Noise Exposure) Regulations 1989. The action level is now 82 dB(A) and the permissible exposure limit 85 dB(A), each as an eight-hour daily exposure, with peak sound pressure capped at 140 dB(C).
Those figures catch more of the factory floor than many employers expect. Compressors, presses, grinders, granulators, cutting and stamping lines routinely put operators above the action level — and once they are, the employer owes a Noise Risk Assessment, hearing protection and a hearing conservation programme.
Our Noise Risk Assessments are conducted by a DOSH-registered noise risk assessor, and audiometric testing is carried out through a DOSH-registered audiometric testing centre. ProSafe manages both for factories across Johor Bahru, Pasir Gudang, Tebrau, Senai, Kulai and Iskandar Puteri, and puts the controls in place afterwards.
Noise Risk Assessment
Area surveys and personal exposure measurement by a DOSH-registered noise risk assessor.
Audiometric Testing
Baseline and periodic hearing tests through a DOSH-registered centre — static, or a mobile unit at your site.
Hearing Conservation Programme
Hearing protector selection and fit, noise zone signage, training and records, built around your shifts.
Noise Control Planning
Where exposure exceeds the limit, practical engineering and administrative measures ranked by effect and cost.
What the 2019 Regulations set
82 dB(A) — action level
Eight-hour daily exposure at which assessment, hearing protection and hearing conservation duties begin.
85 dB(A) — exposure limit
Eight-hour daily exposure that must not be exceeded. Above it, noise must be reduced at source, not just muffled at the ear.
140 dB(C) — peak
Ceiling for impulse noise such as presses and impact tools, regardless of the daily average.
115 dB(A) — maximum
No employee may be exposed above this sound pressure level at any time.
Registered assessor
The Noise Risk Assessment is conducted by a noise risk assessor registered with DOSH.
Registered testing
Audiometric testing through a DOSH-registered audiometric testing centre, static or mobile.
Is this you?
- You have to raise your voiceto be heard at arm's length anywhere on the production floor.
- Your last noise survey predates 2019and was measured against limits that no longer apply.
- You issue earplugsbut have no assessment showing who actually needs them, or whether they are enough.
- New machinery or a layout changehas altered the noise profile since the last assessment.
- There is no audiometric recordfor employees who have worked in noisy areas for years.
From measurement to quieter work
A noise report that confirms the floor is loud tells you nothing you did not know. The value is in what it says about who is exposed, how much, and which sources are worth tackling first.
The assessment is conducted by a DOSH-registered noise risk assessor. ProSafe then turns the findings into a hearing conservation programme your supervisors can run — noise zones marked, protectors selected for the actual exposure and fitted properly, employees trained, and audiometric testing scheduled through a registered centre so the next test is never missed.
Where exposure is above the limit, we work through practical source controls with your engineering team — enclosures, damping, maintenance, relocation, job rotation — ranked by the reduction they achieve against what they cost.
How noise compliance runs
Preliminary Survey
We walk the floor, identify noisy machines and work groups, and agree the scope of measurement with you.
Noise Risk Assessment
Area mapping and personal exposure measurement by a DOSH-registered noise risk assessor, under normal production conditions.
Audiometric Testing
Baseline and periodic testing of exposed employees through a DOSH-registered audiometric testing centre.
Controls & Programme
Hearing conservation programme set up, noise controls planned, and every retest and review date tracked.
Noise risk assessment — common questions
What are the noise limits under the Noise Exposure Regulations 2019?
The action level is 82 dB(A) and the permissible exposure limit is 85 dB(A), both as an eight-hour daily exposure. The peak sound pressure must not exceed 140 dB(C), and no employee may be exposed to sound pressure above 115 dB(A). Reaching the action level is what triggers the duties for assessment, hearing protection and hearing conservation.
Who can conduct a Noise Risk Assessment?
A noise risk assessor registered with DOSH. A safety and health officer may conduct one only if separately registered for it. Our NRA engagements are conducted by a DOSH-registered noise risk assessor, with ProSafe managing the scope, the site arrangements and the implementation of findings.
Did the 2019 Regulations replace the old noise regulations?
Yes. The Occupational Safety and Health (Noise Exposure) Regulations 2019 replaced the Factories and Machinery (Noise Exposure) Regulations 1989. The action level and exposure limit are lower than under the 1989 regulations, so a site that was compliant under the old rules is not necessarily compliant now.
Who needs audiometric testing?
Employees exposed at or above the action level are enrolled in a hearing conservation programme, which includes a baseline audiometric test and periodic retesting. Testing is carried out at a DOSH-registered audiometric testing centre, which may be a static centre or a mobile unit that comes to your site.
Are earplugs enough to comply?
No. Hearing protection is the last line of control, not the first. Where exposure exceeds the limit, the regulations expect noise to be reduced at source through engineering and administrative measures, with hearing protectors issued, fitted and worn while that work is done and wherever exposure remains.
When does a Noise Risk Assessment need to be repeated?
Whenever something changes that could affect exposure — new or relocated machinery, a new process, a change in shift pattern or layout — and when audiometric results suggest hearing is deteriorating. We track these triggers and the review date so a reassessment is arranged before it is overdue.
Noise at your site boundary is a separate obligation under DOE rather than DOSH — see boundary noise monitoring. For the full set of occupational health assessments, see industrial hygiene services.
Where we work
We arrange Noise Risk Assessments and audiometric testing for factories across Johor Bahru, Pasir Gudang, Tebrau, Plentong, Masai, Skudai, Senai, Kulai, Iskandar Puteri and Gelang Patah. Measurement is always taken on site during normal production — noise exposure cannot be estimated from equipment specifications.
Above 82 dB(A)?
