The impressions which come to us through the sense of hearing
cause sensations agreeable or disagreeable, but even in this
sense we see marked examples of idiosyncrasies and antipathies to
various sounds and tones. In some individuals the sensations in
one ear differ from those of the other. Everard Home has cited
several examples, and Heidmann of Vienna has treated two
musicians, one of whom always perceived in the affected ear,
during damp weather, tones an octave lower than in the other ear.
The other musician perceived tones an octave higher in the
affected ear. Cheyne is quoted as mentioning a case in which,
when the subject heard the noise of a drum, blood jetted from the
veins with considerable force. Sauvages has seen a young man in
whom intense headache and febrile paroxysm were only relieved by
the noise from a beaten drum. Esparron has mentioned an infant in
whom an ataxic fever was established by the noise of this
instrument. Ephemerides contains an account of a young man who
became nervous and had the sense of suffocation when he heard the
noise made by sweeping. Zimmerman speaks of a young girl who had
convulsions when she heard the rustling of oiled silk. Boyle, the
father of chemistry, could not conquer an aversion he had to the
sound of water running through pipes.
