If
there are no obstructions between the listener's ear
and the sound source the direct
sound will be the first sound to reach the ear. This
is followed by a series of discretely separated echoes known as early reflections
which provide cues as to the size of the space the sound occurs in with
longer delays indicating a larger room. |
The
reverberation time, or RT60, is the time it takes the sound to decay 60
dB below its original level (or a millionth of that
original level). Rooms with more reflective surfaces will result in longer
reverb times and are refered to as "live" or "wet", while rooms with very
absorptive surfaces will result in relatively short reverberation times
and are refered to as "dead" or "dry". |
