It must be stressed that this interaction is not unidirectional, and this mutual plasticity between the acoustic object and the perceived sound is part of the focus herein. The result of listening will affect the perception and the memory of the original sound. The original sound is never heard the same way twice. In some ways it can be said that it is never "heard" again.

When the composer enters the studio situation, this dual existence of the acoustic event that is sound and the perceived event that is also sound, results in a resonating, dual plasticity between the two which can be heard in the composer's musical choices.
