WHAT IS SOUND?
Physics can tell us the mechanism by which disturbances propagate through the air. If this is our definition of sound, we have the problem that in physics there are no limits to the frequencies and levels that must be considered. Biology can tell us that the ear responds to only a certain range of frequencies provided a threshold level is exceeded. This is a better definition of sound; reproduction is easier because it is necessary only to reproduce that range of levels and frequencies that the ear can detect.
Psycho-acoustics can describe how our hearing has finite resolution in both time and frequency domains such that what we ...
