Noise reduction

noise reduction

[′nȯiz ri‚dək·shən] (engineering acoustics) A process whereby the average transmission of the sound track of a motion picture print, averaged across the track, is decreased for signals of low level; since background noise introduced by the sound track is less at low transmission, this process reduces noise during soft passages.

Noise reduction

Reducing the level of unwanted sound by any of several means of acoustical treatment.

noise reduction, NR

The difference in decibels between the average sound pressure levels produced in two rooms by a sound source in one of them.
