What Is A-weighting?

- Jul 17, 2018-

Human hearing is sensitive to different frequencies of sound, so we need to modify the spectral measurement techniques to bring them closer to what our hearing can perceive. These modifications are called A-weighting. They are widely used in audio measurements (for example when estimating noise levels or dynamic range). The end result is that we get weakened, inaudible frequencies and the most audible frequencies.
