Not to compress ausaudio As a muffler.. as a filter.. You ever see a water muffler?
What about WET stacks on marine diesels? You'll have to trust me on this one.. A pair of V12 Cats in a tug, can get LOUD (130+ db) yet quiet as a mouse with water muffs..130+ db easy uncorked.
I use to work on Hydro-blasters.. 15,000 psi HP water jets. Water does not compress.. LOL BUT is sure quiets things down, and it transfers SOUND pretty dog on well, too.
Those noisy POS used 6V53 Detroit (2 cycle diesels) with "WATER" mufflers installed into 3000 gallon scrubbers. Noise and Opacity test requirement, because of the location. You had to keep a 25 foot distance between you and the scrubber, too. The harmonics would crumble your bones..
Hydro water plants are the same way.. 15-30 minutes exposure, your DONE. Turbine growl is a bone grinder.
It's easy to fix stuff (Gas Monkey Garage). UNDERSTANDING what it does and is doing is another thing..
I need BASS mufflers, yup Dual INTAKE mufflers :-)
Old Heavy Master Mechanic, that gladly retired..
