You don't need to block the airway. Air and sound move differently, so you absorb on paths that sounds likes to travel and minimize obstruction on the air path.

You don't need to block the airway. Air and sound move differently, so you absorb on paths that sounds likes to travel and minimize obstruction on the air path. Something akin to a Tesla valve.
I'm willing to bet that you can make the exhaust noise near inaudible if you want to. Problem is, it costs a couple 10k dollars or so, and why pay for that if you can just fuck over the neighbour instead?

It also does not have to be a Tesla valve precisely. There are all kinds of mufflers and some of them can no doubt be applied at industrial scale - if one is willing to pay a reasonable amount of money.
