Unfortunately alcohol in medium doses does not appear to improve my
hearing (I actually didn't test my hearing while really drunk but I
would bet it does not help either).
Maybe it's the opioid receptor activation of RR which does the trick
(see my report on mechanisms of action)
What could I use to stimulate the opioid receptors, for trying this theory?
I would like something safe, like a medicine, any ideas?
I've never used recreational drugs. Maybe cannabis (rather safe) would
be worth trying. As I read here
http://www.cannabis.net/opioids/opioid-alcohol.html
it would stimulate the cannabinoid receptor which should in turn produce
opioids and stimulate the opioid receptors.
Any of you has tried cannabis and can tell me if it works without me trying?

Thanks
Also I wanted to report a few more things:
The problem does not seem much related to the absolute volume of the
background noise, but to the amount of frequencies involved (width of
the part of spectrum being equal or louder than the voice I want to
hear). If the background is constituted by a lot of frequencies, my
ability to detect the frequencies belonging to the voice of the person
speaking drops greatly. Then s/he must speak a lot louder for me to
understand. The embarassing thing is that if I go nearer to that person
to hear better, s/he would lower the voice accordingly! Until I ask to
repeat for the 5th time...
The situation at the disco is not much worse than the situation in a pub
where the crowd voices (a relatively wide spectrum) are relatively high
compared to that of a single person speaking. Same problem when trying
to hear a person speaking in a bus.
It's like ADHD where you cannot pay attention to many things
simultaneously because you lack the energy to do that. With hearing it's
the same: many frequencies at the same time cannot be decoded by the
brain, and you also get fatigued by simply trying.
I also did an ABR test in the past (anyone else of you did it? please
report) and also passed that with flying colors. ABR is a hearing test
considered deep & meaningful by ENT people (yet they are unaware of
existence of "CAPD", the doctors I met).
The doctor puts electrodes on the arc around your head between the ears
(the same arc where normal earphones pass, on top of your head). I think
the electrodes are supposed to check the propagation of sound signals
across the head before entering into the brain.
Then they put earphones on you and make you listen a stream of "tick"
sounds, near one to the other. The "tick" sounds, sound like
Dirac-deltas and they seem to cover a wide frequency spectrum, yet they
are very short in time.
I remember as the rate of "tick" sounds accelerated a bit I couldn't
distinguish anymore one tick from the next one because they were too
near. However this surprised me because the rate was not SO high: AFAIR
I thought that if the ticks would be of narrower spectrum (such as the
one of tip of a pencil hitting a table) I would have been able to count
them.
So, while doing the test, I thought it would have revealed faulty
transmission of the signal in the nerves but instead the test resulted
ok. So I would say the problem is not in the nerves transmission but
really in inner part of the brain, where processing takes place I would
say (TP, are you saying that there is absolutely no decoding in the
inner part of the brain or just some decoding is done inside the brain
and some in the optic nerve?)
