I experience a "twitching", or a spasming of the ear drum in
conjunction with certain types of outside noises.  I can only describe
it as a "hiccup" of the ear drum.  It is a definite motor-thing as
opposed to a "sound".  I can feel it more than hear it.   There is of
course, a corressponding noise, but I think the "noise" is simply an
abrupt interruption of  the ambient sounds.  It is mostly during the
day, most often when I am reclining but not always.

These spasms appear to occur in connection with distant sounds that are
inaudable or barely audible to other people.  The sounds that are most
coincidental are low-pitched noises such as the sound of a semi-truck
idling on the street near my home, or the sound of  the rumble of a
distant freeway (that would explain a reduction of this problem during
late-night/early morning hours.  Often the sound that stimulates the
spasm is difficult to pin-point.  There may be an inexplicalble hum
that permeates the air (kind of like the noise from a refrigerator
compressor).

Higher pitched, or loud noises do not seem to cause this "spasm" of the
ear drum.  Some thngs that make the twitching stop: running an electric
fan next to my bed, my speaking, the sound from a television.  As soon
as the sound from the TV stops, such as the momentary silence between
commercials, the twitching starts.

This may seem like nothing to you, but when one is attempting to relax,
this non-rhythmic twitching can make one crazy.

I am a 45 year-old male.  I suffer from allergies and asthma.

Any and all help will be greatly appreciated.
