Paging Formula?
« on: March 03, 2014, 12:15:23 PM »
Is there a resource that you can access to figure out meters of coverage per speaker? I have been pretty much dependant on one of my vendors to determine number of speakers/horns needed per square foot of coverage. I bought a SPL Meter to measure the ambient noise levels, measure the space to be covered and give that info. to him and he tells me the wattage per spkr., number of speakers and the location of speaker. When questioned; he tells me it's a very complex formula that he has in a spreadsheet format that the pc figures for him. I'm assuming there is a resource somewhere that I can learn this process. TIA!!

Rule of thumb:

1 - wall mounted speakers project about 20-25'
2 - horns, while not sounding as good as standard wall mount speakers (almost no bass), project about 30-35'
3 - ceiling mounted speakers.......
      3a - for ADEQUATE sound, place the speakers twice as far apart as the distance from the speaker TO THE FLOOR (10' ceiling = 20' spacing).
       3b - for BETTER quality sound, place the speakers twice as far apart as the distance from the speaker TO THE EARS OF THE PERSON HEARING IT (10' ceiling, room has chairs, average person is sitting 3.5' above the floor: 6.5' to the ceiling = 13' spacing. 10' ceiling in a corridor. Average persons ears 5.5' above the floor: 4.5' to the ceiling = 9' spacing)

Having said this, by all means, talk to Valcom, they're a very good source. You could also talk to Bogen or Atlas.
