Delay time
As shown in the example of illustration, the sound of piano played on
the stage attains the ears of listener as a synthesis of the direct sound
from piano, the indirect sounds which are reflected once or twice by
the reflectors, ceiling and side and back walls, and the reverberation
sounds which repeat infinite reflections until they fade out com-
pletely.
The indirect sounds always pass through longer routes compared to
the direct sound. The delay between the direct and indirect sounds
is called the DELAY TIME, and the level of the indirect or reverberated
sounds is called the PRESENCE LEVEL.
The indirect sounds accompanied with delay play a very important role
in providing better sound effects and the feeling of presence of
concert halls, etc. The acoustic field also varies depending on the
speaker arrangement. It is recommended to try various delay time
setting to obtain the best sound field possible.
