What sources of noise are typically monitored on construction projects?

The main noise sources on construction sites are heavy plant and machinery, including excavators, compressors, saws, pile drivers, and vehicle movements. Demolition and concrete cutting tend to create sharp, high-volume bursts of noise, while general construction equipment produces a steady background hum.

Monitoring focuses on the total sound levels rather than specific machines. However, identifying the noisiest tasks helps contractors plan their schedule — for example, limiting high-impact activities to certain hours or using acoustic screens around fixed equipment.

It’s really about knowing where the noise is coming from and keeping it within reasonable limits for the surrounding area.
