We looked at this when I began an electronics degree at UCL in 1978.
You can also prove that the eye is just sensitive enough to detect one photon of light, below which threshold no useful information could be conveyed. The approach then was about information gathering rather than the observation that "you'd hear air molecules jostling all the time if your hearing were more sensitive." I forget whether we looked at other senses, but on QI a while back I saw something about the sense of touch and it seems that rubbing your finger gently back and forth over something can detect things 1/1000th the diameter of a human hair - possibly the size of one atom of something. I can't remember the details - you'd have to Google that.

Excellent post Pat . For some reason the Shakespeare phrase "There`s the rub " popped up in that pdf. It was drifting through my mind yesterday for no reason at all .Another mysterious scientific study showed that a caterpillar can have an experience and after that it becomes a crysallis and finally a butterfly , but they demonstrated that the butterfly still remembers what happened to it when it was a caterpillar . All totally off topic of course .

So far I am fairly certain that both my cochleas are working properly . But they keep talking about BlueRay which is foreign territory to me and It seems they only use them for music .I just want a microphone to hear what people are saying .In my left ear speech sounds like a kid banging on a snare drum .

consider your eustachian tubes. I have enormous issues at times with exactly this 'snare drum' sound. If your eustachian tubes aren't working well (mine never have) fluid can build up behind your ear drums and cause this problem. It often takes months (!!!) to resolve this. Still, the good news about this is that your structural hearing is intact and if in fact the eustatchian tubes are the problem, you may solve this with antihistamines. Good luck! Talk to your ent specialist about this if you haven't already.

Thanks Jeffrey . I am still waiting for a so called urgent appointment with the ENT specialist .My doctor keeps making notes about it not being urgent but does not know anything about my ears . Penny pinching I expect .I hope ENT people know what a snare drum is .

I looked at an Aftershokz headset yesterday in a cycle shop . I could not work out if it had a microphone to deal with normal conversations.It just seemed to be for receiving Bluetooth signals from MP3s or telephones . The salesman had no idea . I wrote a question to an e - b a y seller (in China where they make them alll ) and they just sent the original advert back to me about microphones. (with mic or maybe not ).

This BBC news item about American deaf singer, Mandy Harvey, though not about aiding, might be of interest to visitors to this thread.
