There is a significant difference between the nature of ‘environmental’ noise versus ‘occupational’ noise.’
Environmental noise is defined as any unwanted sound in the vicinity of the home or its surroundings – including industrial noise from construction sites or noise from traffic or other forms of transport. It’s usually measured at much lower levels, and often linked with transport, road traffic, rail traffic, air traffic, and from industrial sites, often termed ‘nuisance’ noise.
Occupational noise is generally encountered within the workplace, where some noise is to be expected and deemed ‘acceptable’, and where the measurements of worker exposure can be measured against regulated hygiene limits. [see article]
The way we respond to environmental noise can vary widely between individuals. Some people experience psychological or physical effects because of exposure to a particular ‘nuisance’ noise. Whereas others may not even notice the noise, or if they do, not be adversely affected.
BS4142:2014+A1:2019, the method for rating and assessing industrial and commercial sound, provides a way of assessing the likely impact of a source of industrial or commercial ‘noise’. It is the UK’s most widely used standard for the assessment of environmental noise.
BS4142:2014+A1:2019 uses a 'rating level' – this is based on a comparison between the noise which is being assessed and the background noise which would exist without it. The rating level is then modified by any corrections for the character of the sound, be that tonal, impulsive, or intermittent. Therefore, measurements need to be taken at different times of the day and night to assess the excess of rating noise over the background noise.
