Ability to detect sound changes over time.
Sound completely or partially covered by another.
Time for the hearing system to register the full volume of a sound.
Tiring of the auditory nerves that result in a loss of awareness of a particular sound
If using a multispeaker projection, a sound coming from the right speaker will reach the right ear first, creating a temporal delay and sound shadow in the left ear; making us perceive upon hearing that the sound is coming from the right hand side.
