Psychoacoustics  ::   Hearing  ::   Loudness  ::   Pitch  ::   Harmony  ::   Scales


The human auditory system is complex in structure and remarkable in function. Not only does it respond to a wide range of stimuli, but it precisely identifies the pitch and timbre (quality) of a sound and even the direction of the source. The frequency range of hearing extends from 20 to 20,000 Hz for some, substantially less for others.

To successfully complete this chapter you should...

  • Read chapter 5 in your text book (pages 53 - 62).
  • Carefully study the important concepts about hearing.
  • Be able to list the parts of the ear and describe its function in hearing.
  • Be able to use logarithms and the logarithmic scale.
