I looked all over the internet for some info on this, but did not find anything. When I looked on here all I could find were threads on Smoke alarms.
I ran out of my home today to mail a letter and heard a Beep Beep Beep sound that was coming from a construction site where building a new home, I could barely seen the bulldozer through the trees, but I could hear the Beep Beep sound. The site was about 1000 feet or more from me, and I ran back into the house right away to get out of the sound. It may have beeped 3 times before I was in. But sure enough 5 minutes later I had a bad spike. I just could not understand how that happened ? I would think at over 1000 feet away that It would not have been a problem. I did check the internet to see how loud these alarms are and it seems to be around 87 to 97 DB at the source. But does anyone know how many DB's it would be at like 1000 feet from the source ? I can't even find any chart on that, maybe some on might know. I would guess its under 45 DB at a 1000 feet away or more.
Anyway I was just wondering if anyone here has had problems with these kinds of backup alarm horns ? at this distance giving them a spike, and if so how long did it take the spike to settle down ?
Thank You for any info, I know that it's a crazy question but I would value any input.
