Not sure if this is the right place, if not I can move it.
Hello I'm looking for a solution to a problem and it occurred to me, my fellows in fandom likely already solved this issue. We need better communication though our respirators as my immune compromised dad gets cancer treatment. The setup I need would be a small wireless mic, that can fit in a M3 P100 respirator and can FM broadcast or Bluetooth to a speaker. A throat mic might work as wellber and might better because its just a wired on off switch and he would likely need me to set up a wireless system each time. my concern is we are all heavy and I hear throat fat might be a issue. The 3m and MSA units have a fold in the rubber around he seal so there is a bit of space to work with, and I am a maker so building stuff is in my wheel house so ditching a casing and changing things out is pretty easy for me.
What do you guys use for this stuff?
