Weird stuff.
I really can't imagine what it would be like. I have hearing aids, and currently have about 78% hearing loss in both ears. Due to a youth of guns, mechanics, drums, and rock and roll. So sound and how it relates to the world around me has always been a little strange and intriguing to me. I can tell you that pressure has a lot to do with hearing. My hearing aids attest to that in pressurized environments. Whether a room is sealed, pressurized, etc. has a lot to do with how you hear. And there is a huge amount of what you hear that is processed by your brain without you knowing. You don't simply hear everything the same way. For instance, your brain has a way of muting your own screams and loud yells, so you don't hurt your own hearing. And in noisy conversation environments, your brain has a way of locking in to who you're communicating with and muffling background noise. Hearing aids completely fail to overcome those minor brain processes, which are blatantly obvious in some situations. I'm convinced that your brain shapes and adjusts what you hear much more than people realize, and plays a big role in how you perceive and navigate your environment.
