Hi, a recent career path change has put me to work with Hyperbaric Chambers, I'll be assisting in design changes, maintenance side of things, and so on.
The chambers we use are 100% oxygen monoplace chambers, and one thing I'm looking at is communication to the patient, one mandatory requirement as stipulated by FDA (US) and TGA (Australia) is that there can be no powered devices inside the chamber, pressurized air chambers with oxygen masks are allowed basic low wattage speakers.
So the solution has been to use sound powered phones, exactly the same thing submarines use when they go silent

Below is the receiver and communicator that sits on the outside, now this design is different in the fact that it transmits vibrations to a magnet speaker that is directly screwed to the chamber hull itself, (which is a 5/8" thick stainless steel vessel) and turns the hull into the speaker

The chambers don't really need the communications, as you can just raise your voice slightly more and can still be heard fine through the hull, plus the view ports also allow visual communication, but its a nice ability to have
What I'm interested to find out is what other possible options are available or could be used, we need something that can be tapped into an external microphone/speaker setup, be used for a DVD player that sits on a hull window and so on.
Something like this for example, the boombox V3 http://wowzer.com.au/boombox-v3 is a vibration speaker, so I am assuming works on the same principal as the communicator.
I'm only seeing what else is available as what is currently on there is over 20 years old in design, I guess though there isn't much technological advancement with sound powered devices though.
Look forward to hearing from the much more knowledgeable people than myself
