Pitch & timbre perception
Deceiving the ear
, Psychoacoustics is the study of human perception
of sound.
This includes how we listen, our psychological
responses, and the physiological impact of music
and sound on the human nervous system.
Psychoacoustic perception can be divided into two
categories:
Psychological response
Neurological response
, A song or melody associated with childhood, a teenage romance,
or some peak emotional experience creates a memory-based
psychological reaction.
There is also a neurological response to sounds, however. Slightly
detuned tones can cause brain waves to speed up or slow down,
for instance.
Filtration and gating are methods that trigger an active listening
response and thus tonifies the auditory mechanism, including the
tiny muscles of the middle ear. As a result, sounds are perceived
more accurately, and speech and communication skills improve.
A growing school of thought — based on the teachings of Dr.
Alfred A. Tomatis — values the examination of both neurological
and psychological effects of resonance and frequencies on the
human body.
