Sound II Reading

Based on the delay time between the source sound and its delayed image we can fool the brain into creating images that aren't really present.

The example below first has the sound source coming from the left monitor. This sound is also routed out, via an aux channel, to the left monitor.

The next example now delays the right side by 20 msec. Notice how the image shifts to the sound coming from the left hand side. The image also appears fuller wider then the image produced without the delay. A delay below 30 msec is known as the Haas Effect.

Delays greater than 30 msec will start to produce discrete echoes. Delayed sounds will be covered in deeper detail in a later lesson. Right now it is important to understand the concept of how the brain deals with delayed sounds.
