I thought in the 1980something brochure that 408 was 115, 612 was 128, and 812 was 132.

Sorry I haven't updated the list lately; I was on vacation.

Are those ATI ratings accurite? I always thought they were a lot quieter than that. 126 dB is on par with the Thunderbolt!

I'll add the WPS 4008, but I don't know about the EOWS series. Weren't the ratings greatly exaggerated?

How in the world could an ATI be anywhere near as loud as a Thunderbolt?

Wait, you're talking about the mini Thunderbolt. Sorry.

My town operates HPSS32 sirens, and outdoor measurements register 127, which is pretty accurate. They are not pleasant to be near as far as loudness, let me assure you.

Sorry for the late reply, but here is my bad picture of a CTI in Okmulgee, Oklahoma. I plan on recording it and Bixby's rotating CTI sometime in the near future..wait damn, surprise ruined... :roll:

I believe the 2001SRNB was 127 and all other models were 126. I may be a DB off there so somebody correct me if I'm wrong.

Really!? I had no idea they were that loud. I thought they'd be like 105 dB or something... :P

That CTI looks kind of like a T-112 with small horns attached.

Let me tell ya, that thing is probably no bigger than a Model 2. I barely noticed it as we drove by. I will try to get better pics of one sometime, but this one is two hours away and the one in Bixby is even farther.

I can get Bixby this summer if my poor Chevy can make it, hopefully.
