On-Site Calibration & Noise Monitoring Compliance

Accurate noise monitoring is more than just taking a one-time measurement. To effectively protect workers and comply with regulations, you need properly calibrated equipment and consistent follow-ups to catch changes over time.

On-Site Calibration: The Non-Negotiable Step

Calibrating noise meters on site – both before and after use – is essential. Relying solely on infrequent third-party calibration or cheap off-the-shelf meters won’t cut it. To meet HSE standards, meters should have at least a Class 2 microphone.

Real-World Insight: A Factory Noise Survey

During a recent survey, our team detected a piercing high-pitched whistle on the fifth walkthrough of a factory – something that hadn’t been there before. It turned out the CNC machine’s cutting bit was past its prime and the material had changed, increasing noise levels and frequencies.

Why This Matters for Noise Control

Ignoring equipment condition and process changes can lead to higher noise exposure and make engineering controls more complex and costly. Regular monitoring paired with basic maintenance (like replacing cutting bits) can reduce noise risks effectively – sometimes even before considering hearing protection PPE.
