Conventional approaches to film sound work are concerned with attention.
Auditory Neuroscientist Seth S. Horowitz writes that “the difference between the sense of hearing and the skill of listening is attention.” Attention is the faculty that joins us to the world.
The filmmaker orchestrates the various component parts of the soundtrack in order to direct the spectator/auditor’s attention to what is intended to be heard at any particular moment in time.
In film we both look and see, listen and hear.
