Question about siren distance

[Busgeek71]

My town just got a new ATI HPSS32 installed, I think today, but it's a half mile away from two other HPSS32 units, and I wondered if that new siren will be useless since the sound travels about a mile away. Anyone know?

I dont think it would be. As long as it is covered it shouldn't matter how many sirens it takes or how much over coverage there is. As long as there are working sirens that is all that matters.

Well, I know from personal experience and observations of the local siren it depends on three things (mainly)

1. ambient termperature, humidy, barometric pressure
2. background noise
3. how much crap the sound has to get through before it gets there. Trees really suck it up, and the wind blowing through a pecan tree makes a lot of racket too.

it shouldnt be useless even though it is an ATI siren

Adding a fourth to that: pitch. Lower pitched sirens (or tones for that matter) travel a lot further than higher pitches.
