Re: unpleasant sounds

Dear Dr Kearnbach,

I still remember a demonstration of combination tones
by Prof Plomp in one of the famous conferences on Music
Perception in Ossiach in the 80ties. While the stimulus
was generated about 12 meters away from me I felt that
the combination tones were generated in my ear. It gave me
the reaction of goose pimples. Ever since then I have been
wondering whether these unpleasant sounds like scratching
nails on a blackboard may have to do with combination tones.

On the other hand the sound of scratching fingernails on
a blackboard may remember you of the unpleasant feeling
you get when you do it yourself on the blackboard.

Hope this gives you some leads.

Kind regards,

Leon van Noorden
