How do we assess noise?
Noise may be measured using a sound level meter at the source of the noise. Alternatively, an organization or company may measure a person’s exposure to environmental noise in a workplace via a noise dosimeter.
What are some examples of noise?

What is a noise level survey?
Noise survey is conducted in areas where noise exposure is likely to be hazardous. Noise level refers to the level of sound. A noise survey involves measuring noise level at selected locations throughout an entire plant or sections to identify noisy areas. This is usually done with a sound level meter (SLM).
What is noise monitoring?
Noise Monitoring. Noise Monitoring is needed to control the noise level coming from factories, roads and construction sites, which is one of the largest causes of complaints to regulators. The Environment Agency (UK), EPA (Ireland) and local authorities have the power to impose noise limits. Measuring noise is not straightforward.
