@c11 you might want to try and do what i did for the LRR prototype @650 psi, I made a muffler for the exhaust port and it went from an ear drum shattering crack to a dull thud.

I wouldn't use it as an excuse to not use basic safety gear. Not only is it still wise to have them for normal use, but there are noises the suppressor isn't going to make quieter - chamber failure for example.

It also might make it possible to use indoors.

Not really a good idea either. However you look at it, you're still introducing a large amount of air to a room. You might be doing it slower than with an unsuppressed cannon, but it's still pretty damned fast. Suppressors will not have a notable effect on the hearing damage caused by firing a pneumatic cannon in a confined space.

It does depend on how confined the space is, but if there's any doubt about it, don't.

What I'm in the middle of making will have a sound pressure level that could cause permanent hearing damage - even when I'm wearing ear defenders.
Suffice to say, they can be pretty loud.

Now, if you're actually serious that you don't use hearing protection when firing shotguns, I suggest you start - shotguns are easily loud to damage your hearing.

Does that thing kinda look like a big cat to you?
