Document Summary
Tcom 330 - gateway section pm1 - sollars. When sound hits one ear before the other, even if only a millisecond before, the brain can. The shape of the outer ear also helps us determine when sounds are coming from in front of decipher the order in which the ears were triggered and guess at the sound"s location or behind us. Dual mono - two identical channels of audio (l and r are exactly the same) Indirect sound are those that come to our ears after reflecting off of another surface. We can process as different sounds separated by 30 or more milliseconds. Early reflections - inaudible unless 10db or more louder (haas effect) Reverberations / echoes - those sounds that arrive 30 ms or more later. Haas effect: early reflections (occurring within 30 ms of the direct sound) will be processed as a part of the original signal unless they are 10db or more louder than the direct sound.
