Hearing and Volume: Difference between revisions

1. The first one is the "equal loudness curve" (sometime also referred to as Fletcher-Munson curves) that Steve has already mentioned. The main effect is that you have to roll of the low end as level go up (or boost it as the level goes down). It basically compensates that the way humans turn sound pressure (physical property of sound) into loudness (a perception in our brain) is really not the same for all frequencies.
