Testing output from a distance
I need a decent way to check speakers from a distance. Part of my daily test routines is to walk around a store, and try to hear the speaker 50-60 feet above my head. This doesn't always work, retail environments being what they are.
Is there a sound meter, or an attachment for an android phone that i could use to see if the speaker is broadcasting, without having to request a lift, and physically go up to the speaker? A typical retail store that I have to check has over a hundred speakers, all 50-60 feet above the ground.
Suggestions greatly appreciated!
Is this a good question?
