pH adjusted inner ear as hearing aid

change pH of cochlear goop to change sound transmissivity
  [vote for,

This is unbelievable" a pH change of .3 ph units say from 7.3 to 7 transmits sound 70 pt more effectively with ocean water [link]

Thus this hearing aid is either a pill that changes the pH of the inner ear or an absorbable fluid to make sounds 70 pt or more louder Most tissues have a pH range more than a 1 wide like 6.5-7.5 thus it may be possible to triple perceived audio volume with a peculiar fluid made of dmso plus buffered pH adjustment chemicals (possibly Magnesium Chloride plus Hydrogen Chloride) DMSO plus lipid surrounded buffered hyperacids

Once the dmso or lipid vesicle carries the buffered acid or minute amounts of superacid across the tympanic membrane the pH changes causing the sound to transmit more effectively

I think it might be possible to combine a photolytic compound like methylene blue plus the lipid surrounded buffered hyperacid to create amplifier chemistry that could be fitted with a beam of light

anyone know how to make a pill

the mechanism of sound through water is described: the chemistry of seawater could change by 0.3 pH units by 2050 (see below for background information on pH and ocean acidification). In the October 1, 2008 issue of Geophysical Research Letters, Keith Hester and his coauthors calculate that this change in ocean acidity would allow sounds to travel up to 70 percent farther underwater

change pH .3 units make things 70 pt more audible http://www.eurekale.../mbar-cut092908.php

       what works for seawater might not work for "cochlear goop"
FlyingToaster, Mar 10 2009

       A change that small is quite trivial, though i suppose it might make a difference between inaudibility and audibility. A more serious problem is altering the pH of the internal environment. It might be possible to do this by holding a mouthful of vinegar but it would rapidly be cancelled out. One thing that could probably be done would be to use a small quantity of heavy water. Any change would be brief. I think it would probably damage nerves in the cochlea, and that density is a better bet than acid.   

       It's a shame people don't hear with their kidneys or stomach.

       This is stoopid, but only for three reasons.   

       1) Nobody is getting their hands on my cochlea. In particular, I don't want it's pH messed around with.   

       2) The effect is most noticeable for low frequency sounds - bottom of the piano keyboard. Useful for slightly-deaf bass guitarists, perhaps.   

       3) It won't work. If your cochlea were, say, a mile long, then it would be fine. But (in truth and without boasting), I bet your cochlea is a lot smaller than that. Very little sound energy is actually lost by absorbtion in the cochlear fluid - almost none, in fact. Reducing those tiny losses will have no significant effect.   

       D-, more effort needed.

       //transmits sound 70 pt more effectively //
does not even remotely imply:
//make sounds 70 pt or more louder //.

       This is meaningless without citing actual measurement technique.

       This is unbelievable
normzone, Mar 10 2009

       I'm convinced you critics are right about this   

       the attenuation is nonsensical   

       nevertheless you ought to be better able to hear the faintest whispers kind of like horton the elephant
