BACKGROUND
NOISE LEVEL
[Film Technology]
[Film Technology]
[Interference]. With
any sound recording
system there is an inherent background noise level; on magnetic Sound tracks this is caused by the oxide coating and on optical
sound tracks by photographic grain particles.
Background noise becomes more obvious when tracks are recorded at very low
level. Recording at a very high level, on the other hand, can over modulate the
tape, causing distortion and possible print
through of the sound on to adjacent turns on the reel.
