DyNAMic RANGE

The difference, in decibels, between
the loudest and the quietest portion of
a program is known as its dynamic
range. Sometimes, the quietest portion
of a program will be obscured by
amb~ent noise. In this case, the dynarmc
range is the difference in dB
b
' ,
etween the loudest part of the program
and the noise floor. In other
words, dynamic range defines the
maximum change in audible program
levels.
Dynamic range also applies to sound
systems. Every sound system has an
inherent noise floor, which is the
residual electronic noise in the system.
!he dynamic range of a sound system
IS equal to the difference between the
peak output level of the system and the
electro-acoustic noise floor.
