Just some facts here:
out door wilderness level 30-40 db
Human talking 70 db
Human yelling 88 db
Boat decibel limit at idle 88 db
Referee whistle decibel > 100 db
foghorn >130 db
These levels are all level at source type measurements. So apparently if boat exhaust is to loud, people best not being yelling around the lake either.....
Read up and understand why the levels that where chosen where chosen. They aren't random numbers. I wrote a big long post on this a couple of years ago...
The real issue here, is how sound travels over water.... on quiet nights I hear conversations from across the lake...
There should be absolutely no problem hearing a cry for help, or a distress whistle, over the noise of boat traffic even on the busiest of days, as long as you are in the vicinity of the problem.
If someone yells for help in Center Harbor, of course you not going to hear it in Meredith...
