Noise

Noise is measured in decibels, dB(A). The decibel scale measures the frequency response of human hearing. An ‘A-weighting’, sometimes written as ‘dB(A)’, measures average noise levels. A ‘C-weighting’, or ‘dB(C)’, measures peak, impact or explosive noises. The decibel scale is logarithmic. This means that an increase of only 3 dB doubles the noise level at the human ear, halving the time a person should be exposed to the noise once harmful levels are reached. For example, you might just about notice a 3 dB change in noise level because of the way our ears work. But every 3 dB doubles the noise level, so what seems like small differences can actually be significant.
