Wastewater Treatment Plants | eNoise Control

Wastewater treatment plants (sewer plants) contain several large pieces of mechanical equipment to clean used water and sewage so it can be returned safely to our environment. These pieces of equipment and processes create high noise levels. Hydraulic pumps, generators, gensets, noisy pipes, and exhaust fans are all components in the wastewater industry that create noise. Complaining neighbors ...

Safety and Health Topics | Occupational Noise Exposure ...

Noise is measured in units of sound pressure levels called decibels, named after Alexander Graham Bell, using A-weighted sound levels (dBA). The A-weighted sound levels closely match the perception of loudness by the human ear. Decibels are measured on a logarithmic scale which means that a small change in the number of decibels results in a huge change in the amount of noise and the potential ...

Noise | Safe Work Australia

Work-related noise-induced hearing loss is a preventable but irreversible condition that affects many Australian workers. Between 28–32% of the Australian workforce is likely to work in an environment where they are exposed to loud noise at work.


An acceptable noise level depends on the specific use of the space, so each number rating typically represents a range of ±5 dB for the design target. For example, private offices and conference rooms are listed as NC/RC 30.


If noise cannot be controlled to an acceptable level at the source, attempts should then be made to control it at some point during its propagation path; that is, the path along which the sound energy from the source travels.

The Noise at Work Regulations 2005, University Safety Office

The damaging effects of noise are related to the ‘dose’ that the ear receives and this depends on the duration of the exposure and the noise level. Equal doses will cause the same amount of damage. Therefore short exposure to high levels of noise will cause similar damage to lower levels of noise exposure that are of longer duration.
