Different noise.* Home toilets work by gravity and siphoning.* The most noise comes from breaking the siphon.* That is the part that is hard to quiet down.* Marine toilets have a prolonged pump and grind noise that resonates through the structural members of the boat.* Spaces are small and hard to isolate noise wise.* It makes it a very difficult problem to solve.* Even though some are advertised as quiet flush, they are not quiet.* The Vacuflush is the quietest head that I have had, but they are no fun to change the duckbill valves.*

Maybe we should work on a human system that uses food to 100% efficiency and produces no waste.

RE: Noisy electric heads

Marine toilets have a prolonged pump and grind noise that resonates through the structural members of the boat.

That may have been true of the original macerating toilets, but the discharge pump and macerator are NOT what makes all the noise in today's macerating electric toilets It's the INTAKE pump on toilets that use sea water that does.* Toilets designed to use pressurized flush water are actually quieter than most household toilets.

The vaccum pump in a VacuFlush is an exception .* Only someone who's never had the vacuum pump installed under his berth would think that it's quiet...A "night switch" in the head to turn off the pump when you retire for the night is mandatory!
