WTF? Can't they put a muffler system on them, or is it the blades that
make the most noise?

Trust me. The engine is loud.
The prop is much, much, louder.

Down at Wootens the make the passengers and the drivers wear ear
protection. I don't know of anyone who doesn't.
I do know a couple guys down in Everglades City who have airboats.
So, why not put a shroud round the prop, it shoudl at least silence it
some?
No ear protection offered here. The boats are load at WOT but not
deafening.

The owner says he has never heard a complaint.



Aside from the particular sound pressure levels, how is an airboat
supposed to sound much different than a low-flying (very low flying)
single-engine prop airplane right over your house or in your front yard?
When we lived in Florida, we weren't very far from the St. Augustine
airport. The airport generated some loud noises once in a while, when
the military reservists played with their jet engine, but we rarely
heard any sounds from the general aviation craft, prop or jet, or even
the small commercial jets that landed there. Even the seaplanes were
quieter than the airboats.

On weekends, before we got some enforcement of noise pollution measures,
we had a couple of airboaters whose special delight seemed to be to get
an early Sunday morning start.
