Use an ear horn to communicate by ear.
Standing by the old man's bedside it was clear by
the shallowness of his breathing and by the near
flatness of his bedsheets that there was not much
left of him.
Leaning down to say my final goodbye into the horn
protuding from his ear I heard a faint beating. I
stopped frozen on the
spot and listened there
closely to the intermittent rhythm. If finally
stopped and I placed my hand over his heart.
His heart was still faintly beating. If not his heart,
then what? The beating resumed and it produced a
steady although unpredictable rhythm. The sound
seemed to have no origin.
It wasn't long before the old man expired. The
attending doctor removed the earhorn and inspected
it. "This is not a typical earhorn", he said. "I had
been using this device to communicate with the
deceased in his final weeks, he had developed
remarkable control over spasms of the inner ear and
could send morse code signals with his tympanic
membrane - these are amplified by the horn".
It's been several years since that day and earhorns
have now advanced to the point that synthesized
speech can be performed through the ear. Even
though it's been so long and much has happened I
can still remember that beating perfectly. Maybe I'll
get around to learning morse code one day.
Some info on ear noises
The person who owns the relevant eardrum will always hear something. I once read that sometimes others can hear something coming from that eardrum, also. I've never bothered to find out if it was true. [Vernon, Oct 13 2012]
||I dread to think as to where you would insert a foghorn.
||Hmmm I don't know about tympanic membrane spasm control but I can open and close my eustachian tubes at will. It makes a sharp crackle of done quickly and a conch-shell-ocean sound when held open. Morse would be a cinch.
||In a strange instance of reciprocity, there is a Dutch
hearing aid which relays sound through a dental
implant, for people with damage to their middle ear.
||If the "horn" had a paraboloid form
resembling the Poisson distribution, would it
make it possible to hear ringing in the ears?
