We did that in airports. When it got noisy then the PA became louder. When it became quiet then the PA was less loud.i want to increase or decrease sound level of speaker depending on sound level or noise created by people in the room .if there is silence in the room the speaker sound must be low and vice versa..
It is more complicated than that:thank u audioguru .should i use mic to detect sound level in room and then use it as feed back to volume control of speaker
Really? So if audioguru doesn't say anything nobody else is allowed to? Gee sorry about that.if u dont want to help then dont..
but mind ur tongue..
i was not asking u fr ckt so mind ur own buissness .
and dont interfere.
if Mr Audioguru didnt say anything u have no right.
