darth, that's an interesting technique regarding the hearing recovery. I had some severe otitis media when I was growing up and I think it affected my hearing, as my ears are very sensitive (I also play drums/guitar/bass/etc and ear plugs have always been a must for me....I've noticed that my ears are more sensitive to loud noises than anyone else I know.)
I've done some research in acoustics and a decent part of it is on human hearing. to the best of my knowledge, the little hairs dont have that significant of an impact.
it also depends on what kind of hearing loss; it can be due to nerve damage (I'm not sure if the cochlea falls into this area, I think it might....but this type of nerve damage is usually caused by some sort of disease, i.e. meningitis) or conductive, where the ossicles (bones) arent transmitting sound properly. (that's how loud sounds damage your ears; if your eardrum's amplitude travels outside of its good working range, damage results. it was pretty interesting reading about how the function of the ear almost perfectly translates vibration from an air meduim to a liquid meduim.) it can also be a combination of both.
after some consideration, I believe it would be possible to marginally improve hearing using that method, but I think you'd need a pretty quiet room. (and lots of time spent on it, but that's a given with such things, right?) heck, if its quiet enough, you should be able to hear your heartbeat clearly and (I've heard...from a pretty reliable senior sound & vid engineer that I'm lucky enough to be able to pick his brain every so often...) even 'hear' or feel the air pressure on your eardrum. most of us arent that lucky to have such a quiet environment though! I'd like to get a studio (soundproof room or two) built for myself when I get around to getting out of my condo and into a house...I'll try this technique out or at least keep it in mind when I've got someplace sufficiently quiet to give it a concerted effort!
