• Auditory Localization
  • The Head in Sound Space.  Illustration of how sound the travelling of sound to the two ears can play a role in determining direction.
  • Time of Arrival and Phase.  Use headphones to experience how the time of arrival or difference in phase between the two ears can be an a cue to the direction of the sound. (Try Interaural Time Differences at ISLE)
  • Relative Loudness.  Use headphones to illustrate to how the relative intensity of sounds in the two ears can influence the perception of direction of a sound. (Try Interaural Level Differences at ISLE)
• Illusions
  • Shepherd Scale Illusion.  Just as a staircase can be drawn that always appears to ascend and repeat itself, so Roger Shepherd devised a set of tones that can be played in a scale that repeats itself.  Each tone appears to be the next higher note in the scale and yet the scale repeats.  Try it out here.
