A-Weighting

Standardized adaptation of objective sound level measurements
(unit: dB) to a normal person's subjective  sound sensation (unit: dB (A)). This adpatation is used to approximately evaluate  the human ear’s actual response to a specific sound event. Generally, measurement devices already apply A-weighting, but if this is not the case, A-weighting can be applied later using standard values.
