SoundMask v0.16
What is an intergalactic sound being supposed to do when people won’t stop breathing on them? Well the only thing they can do: build a better mask! But better filtration isn’t enough! They won’t stop running their mouths! We must drown them out, beat them with their own game! Volume! DECIBELS! Enter the SoundMask v0.16 a half-faceplate respirator equipped to pump out upto a whopping 40W of sheer inexhaustible AUDIBLE BLISS!

Please note: the SoundMask v0.16 is not a functional respirator and should not be used in any context where such a device is deemed necessarily, local laws might govern the use of amplified music, in order to actually use the 40W advertised above one must follow the experimental guide found at the bottom of this document. The respirator has a potential to restrict breathing and your own judgement should be used before assembling or wearing the SoundMask in any context.

The interface might be compatible with other 3M respirators but this is all I have and all I tested it on, it’s modeled on a 3M 60926 cartridge so anything that is compatible with that cartridge should work.

You can probably get away with a thinner gauge but this is what I had around.
