> 82 dB(A)
"Excessive noise" — a registered noise risk assessor must assess the workplace (reg 4). Assessment records kept 30 years.
Hearing Conservation Training & Hearing Protector Programme
On-site training and programme support to comply with the OSH (Noise Exposure) Regulations 2019 [P.U.(A) 60/2019]. Noise awareness, protector selection, fit checks, and record-keeping.
Legal basis: OSH (Noise Exposure) Regulations 2019 [P.U.(A) 60/2019] regs 5 and 7; Noise ICOP 2019 s.11–13; OSH Act 1994 [Act 514]; NIOSH HLPAP syllabus reference (N01)
What the Rules Say
The OSH (Noise Exposure) Regulations 2019 [P.U.(A) 60/2019] set clear duties for employers where noise is excessive.
> 85 dB(A)
Noise Exposure Limit (NEL) — 8-hour TWA. Must not be exceeded. Engineering and administrative controls required; hearing protectors as last resort.
115 dB(A) / 140 dB(C)
Maximum sound pressure level and peak limit. Immediate strict control and hearing protection zone designation.
Annual Testing & Training
Where the limit is exceeded: annual audiometric testing at a DOSH-approved centre (reg 9) and annual training for exposed employees (reg 5(2)).
What Our Training Covers
A practical, customisable programme based on the NIOSH HLPAP reference syllabus (2 days / 13.5 h). Duration and depth adjusted to your site's needs.

Hearing Protector Selection & Use
- Types: earplugs, earmuffs, custom-moulded
- Noise Reduction Rating (NRR) and real-world attenuation
- Choosing protectors for comfort and communication
- DOSH-approved models and where to source them
Fit Checks & Care
- Correct insertion and seal verification

Hearing Protector Fit Checks
Individual fitting of hearing protectors is to be checked (Noise ICOP 2019 s.11.2.6). We offer standalone fit-check sessions and full fit-testing services.
Go to PPE Fit Testing →Programme Support
We train your team and support your hearing conservation programme: noise awareness, hearing protector selection and fit, records, and employee duties.
Noise Assessment Referral
Need a noise risk assessment first? We can coordinate a DOSH-registered Noise Risk Assessor to map your workplace and identify exposure zones.
Noise Exposure Assessment →Annual Refresher Training
Annual training is mandatory where the noise exposure limit is exceeded. We schedule refresher sessions to keep your certificates current and your workers informed.
Programme Audit Prep
We review your records, training logs, and protector issue sheets before a DOSH visit so you can demonstrate compliance with confidence.

Frequently Asked Questions
What noise level needs a hearing conservation programme?
Under the OSH (Noise Exposure) Regulations 2019 [P.U.(A) 60/2019], noise above 82 dB(A) is 'excessive noise' and triggers a noise risk assessment by a registered assessor. Where the exposure limit of 85 dB(A) is exceeded, employers must provide hearing protectors, annual audiometric testing, and annual training.
Who can do the noise risk assessment?
A Noise Risk Assessor registered with the Director General of DOSH. Naja Safety provides this service separately; our Hearing Conservation Training complements the assessment with employee training and programme support.
How often must workers be tested?
Baseline audiometric testing within three months of starting work that exposes the employee to the noise exposure limit. Annual testing thereafter. Records must be kept for the duration of employment plus five years.
Are earplugs enough?
Earplugs are one form of personal hearing protector. The Noise ICOP 2019 says selection should consider the noise level, comfort, and communication needs of the job. Hearing protectors must be DOSH-approved and individually fitted.
What records do I keep?
Noise risk assessment reports (30 years), audiometric test records (employment + 5 years), training attendance records, and hearing protector issue/fitting records. Naja Safety trains your team on what to record and how to keep it organised.
