Noise Exposure Assessment

Workplace Noise Monitoring

Scaada NZ provides occupational noise monitoring and assessment to evaluate worker exposure and recommend appropriate controls. Prolonged exposure to excessive noise remains one of the most common causes of preventable occupational disease in New Zealand.

Our noise assessments characterise the noise environment in your workplace, evaluate personal exposure against the relevant Workplace Exposure Standards, and provide practical recommendations for noise reduction and hearing conservation.

What We Assess

• Personal noise dosimetry — worker daily noise dose (Ld)
• Area noise surveys and noise mapping
• Evaluation against WorkSafe WES limits (85 dB(A) 8-hour TWA)
• Peak noise level assessment
• Hearing protection adequacy review
• Recommendations for engineering, administrative, and PPE controls

When to Request a Noise Assessment

A noise assessment is appropriate when workers are regularly exposed to elevated noise levels, when hearing protection is in use, or when you need to establish a baseline for a hearing conservation programme. Many businesses are required to assess noise under the Health and Safety at Work Act 2015.
