Untreated
gate area
The message is being
blurred by excessive gate
reverberation and masked
by noise from people in the
gate, compromising speech
intelligibility.
Treated
gate area
Reverberation in the gate
area and noise build-up are
both being controlled.
This way, speech intelligibility
is maximized and the message
can be clearly perceived.
