Noise control is an active or passive means of reducing sound emissions, often incentivised by personal comfort, environmental considerations or legal compliance. Practical and efficient noise control is wholly reliant on an accurate diagnosis of what is causing the noise, which first involves finding the source of noise. Once the source of noise has been found, the focus is reducing the noise at source by engineering means.

The most common noise sources can be divided into aerodynamic (fans, pneumatics, combustion, etc) and mechanical (impacts, friction, etc). Effective noise control focuses on reducing the ...
