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.

Recent sunglasses brand with built in bone conductors. Look up "Zungle Panther" - I have no idea about whether they are good bad or indifferent. I came across them completey by accident here: https://www.jn.pt/inovacao/interior/zun ... 52613.html (in Portuguese :-))

Half way through November 2017 I ( I might need to refer back to that date ) and the NHS gave me a date (Dec 1st ) to ring them for the Ear Nose and Throat appointment. They gave me a password in case I was an imposter . So the "urgent" appointment I expected will be sometime in Feb or March 2018 .
Trying to be more self sufficient I had ordered a Bluetooth bone conduction headset with mic. That arrived this week . The mic sadly is not for catching sounds in the air but for talking to a telephone in your pocket . Which in my case I do not have .These Bluetooth gadgets talk to each other . If you have no other gadgets for them to talk to ,it`s all about finding a suitable dongle. My wife does not have a dongle . I will be able to connect to a laptop or tv but not my wife . There , I will be struggling .
Yesterday I was under the illusuon that Bluetooth was a higher quality sound system . Another mistake .
A microphone would seem to be the answer but all I keep finding is a selection of Karaoke mics. That`s not my scene at all .
I feel as if I have been hung out to dry .

Same evening as the previous post. My son popped in and I asked him to Pair his mobile with my Bone Phones. It worked first time and with some piano music playing I had a fairly muted sound on the good ear and almost nothing on the left side. But my wife has hearing aids too . She tried them on and was delighted at the sound quality . They are a much better fit for her as my big skull is a stretch for the phones which have no adjustment for size .Think about hard hats on a building site. They have adjustable plastic bits .
So not a waste of £30 and an early Christmas present for my wife . There are larger ,probably more powerful ones in Connevans for about £18 (one side ). I can hide it under an old pair of headphones I suppose . Anyway , some progress .

I have ordered another type of bone conductor from Connevans . They have a one sided model with a plastic pad on the empty side . The sales lady says it will work both sides on it`s own . Maybe this is the only true bone conduction phone being made. About £53. so it won`t break the bank . It has a plug in patch wire and will not create an echo like the Bluetooth models . Functional rather than trendy . See below .

When the Single Bone Conduction model arrived I was almost afraid to try it . First impression was the metal spring over my head was a bit narrow and stiff. Connecting the patch lead to the tiny conduction unit was simple and it was plugged into the laptop . Left side was completely silent. The right side seemed to be influenced by my hearing aid . So I took that away and quite frankly I heard the very faintest sounds with a music video . So faint it was not worth listening to . That was my "good ear ".side .
My wife tried it as well . Quite faint but she heard more than me . The bone condutor from China I got last week was streets ahead for my wife so I have sent for a dongle to use on the set top box. It has two different plug shapes and a short aerial .

Trying the bone conductor on a laptop is not much good. It has such a weak signal .So I found the earphone socket on the back of the tv. It vibrated very strongly at max volume so I was able to establish at long last that my left cochlea is pretty much useless . That is what I needed to find out and not wait till March 2018 and my next appointment .The clarity with the beige bone vibrator was not nearly as good as the Chinese one . I heard plenty of sound but most was muffled with my "good ear". In my left ear --Zero .
The dongle arrived for the Chinese conductor but it works only with both the usb and the 3.5 plug inserted. That means my Bang and Olufsen tv will not suit it . The plugs are older generation . This was the last cathode ray set they made .Maybe I can convert it . The picture is perfect . Subtitles are as usual --Rubbish . They used to be quite good in French films with Bardot on screen . Happy Days .

There is a last chance saloon if your cochlea packs up . That is a little operation behind the ear to implant three contacts in the "brain connection" nerves to stimulate the hearing . It bypasses the cochlea and sends signals from a hearing aid style transmitter . Not particularly dangerous as an operation but a good fallback if you worry that the "good ear" might go downhill too . A lot of advice about hearing is doled out yet they seem to forget that both ears will rarely go wrong exactly together. It`s possible to monitor the progress of a bad ear with a good ear .

By a strange coincidence My sister in law phoned to wish me Happy Birthday and I tried the phone on the left side . Not a sausage . I joked about having an operation and drilling a hole in my skull to fit the new bits. That same evening there was a hospital surgeon program about exactly that . A guy having a hole drilled in his head to fit a microphone . And it worked well too . My drilling will need to be a little deeper as his implant was in the middle ear .The danger was steering between two nerves . One would lose the sense of taste and the other one , the sense of smell . Quite a long operation if you fancy having a go .
