Amplitude and Perceived Loudness

  1. Jan 27, 2010 #1

    If amplitude is doubled, is perceived loudness necessary doubled?

    If I recall correctly, we hear things on a logarithmic scale.

    You are correct. While loudness doubles, the human ear interprets different frequencies differently. This is why there have been different weighing functions, i.e. dBA, dBC etc...
