What is C weighting used for?

C Weighting is usually used for Peak measurements and also in some entertainment noise measurement, where the transmission of bass noise can be a problem. C-weighted measurements are expressed as dBC or dB(C).

When should I use weighting?

Because A-weighting readings reflect the sensitivity of the human ear, they are commonly used to assess potential hearing damage caused by loud noises (such as aircraft or trains) and are used globally to evaluate environmental hearing damage risks.

What is frequency weighting A & C?

Measurements made using A-weighting are usually shown with dB(A) to show that the information is 'A' weighted or, for example, as LAeq, LAFmax, LAE etc. 'C' Frequency Weighting. This is a standard weighting of the audible frequencies commonly used for the measurement of Peak Sound Pressure level.

Which weighting best represents typical human hearing response at loud listening levels?

A-weighting is valid to represent the sensitivity of the human ear as a function of the frequency of pure tones. The A-weighting was based on the 40-phon Fletcher–Munson curves, which represented an early determination of the equal-loudness contour for human hearing.
