Noise Testing

Hazmat Plus can provide a detailed noise test for your site including an initial noise hazard risk assessment using a Class 1 sound level meter, noise “grabs” of individual areas to identify noise-producing machines and personal noise (dosimetry) monitoring over a typical work shift to compare results against current Workplace Exposure Standards.

Noise is a common workplace hazard and is often underestimated as hearing loss can be gradual over many years. All workers exposed to high noise levels are at risk of suffering permanent noise-induced hearing loss. Monitoring workplace noise is with professional noise testing is crucial in the management of noise on a site and is the only way to determine your workers noise exposure.

How a noise assessment should be done in the workplace?

A noise test or noise hazard risk assessment begins with a noise survey using a Class 1 sound level meter. This is followed by personal noise monitoring and short recordings of noise levels to identify loud machinery. Results are compared with the Workplace Exposure Standards.

How often should a noise assessment be carried out?

A noise test or noise hazard risk assessment should be conducted every five years to ensure a safe working environment. However, if machinery, work processes or working hours are altered or structural changes are made to the buildings, a new noise survey should be performed. 

How to assess noise?

A workplace noise test, noise survey or noise hazard risk assessment is usually conducted using a sound level meter (SLM), integrating sound level meter (ISLM) or a noise dosimeter. These can be used to identify the level of personal noise exposure, as well as noise generated from a specific source.
