Definition - What does C-Weighting mean?

C-Weighting refers to noise measurement at different sensitivity levels. Frequency weightings are used in sound level measuring devices. C-Weighting measurements are recorded as decibels and are typically used for higher peak noise level measurements. C-Weighting is sometimes used to measure entertainment noise levels where bass levels can be quite high.

SureHire explains C-Weighting

C-Weighting is a standardized way of measuring noise frequencies by sound meter devices. The response of the human ear to different frequencies varies depending on the level of noise. C-Weighting measures evenly between the frequency range of 30 to 10,000 Hz, and is measured in decibels. This weighting scale measurement is ideal for monitoring loud noises such as engines, explosions, high power machines, as well as very loud music or entertainment noises.
