How Often Do You Need Noise Monitoring? Singapore Legal Guidelines Made Simple
Excessive workplace noise isn’t just a health risk — it’s a regulatory concern in Singapore. Many businesses aren’t sure how often they need to conduct noise monitoring or whether it even applies to them. This article simplifies the legal requirements for Noise Monitoring under the WSH (Noise) Regulations.
What Is Noise Monitoring?
Noise Monitoring is the measurement of sound levels in the workplace to identify if workers are being exposed to hazardous noise. The main purpose is to prevent Noise-Induced Deafness (NID), which is permanent and irreversible.
Singapore’s Legal Requirements (WSH Noise Regulations) According to the Workplace Safety and Health (Noise) Regulations, employers must take action when employees are exposed to noise levels at or above 85 dB(A) over an 8-hour workday.
You MUST Conduct Noise Monitoring If: 📌 10 or more workers are exposed to ≥85 dB(A)
📌 Noisy work activities take place regularly (e.g., grinding, drilling, machinery use)
So, How Often Is It Required?
Under the law:
✅ Initial Noise Monitoring: Must be carried out within 3 months of identifying potential noise hazards.
✅ Re-monitoring (Periodic Monitoring):Must be done at least once every 3 years, or sooner if:
📌 Work processes change
📌 New machinery is introduced
📌 Workplace layout is modified
📌 Noise complaints or hearing loss cases arise
Report Submission: The Noise Monitoring Report must be submitted to MOM within 30 days of completion.

Why It Matters?
Legal Compliance: Avoid penalties and ensure your company meets MOM’s safety standards.
Worker Health Protection: Prevent hearing damage, one of the most common occupational diseases.
Project Eligibility: Companies on high-risk sites are often required to provide updated Noise Monitoring Reports to qualify for tenders or audits.
Common Industries That Require Noise Monitoring:
✅ Construction
✅ Manufacturing & Engineering
✅ Shipbuilding & Offshore
✅ Logistics & Warehousing
✅ Automotive & Fabrication Workshops
Final Thought: Noise Monitoring isn’t optional — it’s part of your responsibility as an employer.
Doing it regularly helps you stay on the right side of the law while safeguarding your workforce damage occurs
✔ Fulfil legal obligations under MOM’s WSH guidelines
📋 When Is Audiometry Testing Required? If your employees are exposed to noise levels at or above 85 dBA, audiometry testing is mandatory.
According to the WSH (Noise) Regulations: A baseline test must be conducted within 3 months of employment in a noisy environment Annual follow-up tests are required Records must be maintained for at least 5 years
Industries Where Audiometry Testing Is Crucial: ✅ Construction & Renovation
✅ Manufacturing & Engineering
✅ Marine & Offshore
✅ Oil & Gas
✅ Logistics & Warehousing
🔍 Why Early Detection Matters Noise-induced hearing loss is permanent but preventable. Audiometry testing allows companies to act early — whether by adjusting work processes, providing better PPE, or relocating affected workers.
It’s not just about compliance — it’s about protecting your team’s long-term health.
