Coverage
The distance you can be away from a speaker and still
have good talkback depends on the type of speaker
and ambient noise level.
The speaker should be as close as possible to the area
where talkback is desired. It should not be mounted
close to, or pointed at, noise producing equipment
such as fans, air conditioners, machinery, or
compressors.
The chart below shows maximum talkback distances
relative to the noise level of the surroundings.

your ears. If you can not carry on a
conversation at normal voice levels over the
required talkback distance, then talkback
page equipment will not function
satisfactorily.
