NOISE POLLUTION

Construction sites are a major contributor to environmental noise pollution and can cause problems for builders and contractors alike. Environmental noise can also give rise to noise complaints, which often have a negative impact on construction activities and can possibly cause setbacks to project completion dates and budget overruns.

Some of the most common complaints on sites are that hearing protectors are uncomfortable giving to the argument that they can create a situation where they cannot hear warning signals or communications from fellow workers.

There is evidence that exposure to high noise levels can act as a stressor, which over a long period of time can result in varying side-effects. While consideration has to be also given to the wider community around a construction site, it has been established that the exposure of construction site workers to noise pollution is significantly greater than that of the public at large.

Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.

The Four types of noise

  • Continuous noise. Continuous noise is exactly what it says on the tin: its noise that is produced continuously, for example, by machinery that keeps running without interruption.
  • Intermittent noise. …
  • Impulsive noise. …
  • Low-frequency noise.
