Purpose:
• To give the student knowledge of the anatomy,
physiology and psychology of hearing.
• To give the student knowledge of the planning of
psychoacoustic experiments.
• To give background knowledge for design and
construction of sound reproduction
systems.
Contents:
Module 1 – Physiology and Psychometry
Anatomy and physiology: Anatomy of the human
ear. Temporal integration and time
constant of the ear. Audiology, audiometry,
tympanometry and otoacoustic
emissions.
Hearing disorders, diagnosis and
treatment.
Psychophysics and psychometrics: Absolute
threshold and just-noticeable difference,
balancing and scaling measurements, psychometric
function, Weber’s rule and
Stevens’ power function. Hearing threshold and equal loudness
contours, auditory
adaptation and fatigue.
Design of psychoacoustic experiments:
Adjustment method, method of limits and
method of constant stimuli, adaptive methods,
forced choice methods, information of test
subjects, statistics, randomising.
Module 2 – Psychoacoustic Phenomena
Critical bands and masking: Psychophysical
tuning curves, post-masking and premasking,
pulsation threshold.
Pitch of pure tones and its dependence on
intensity and tone duration, octave
matching, pitch of complex tones and virtual
pitch, repetition pitch. Beats and
combination tones. Subjective
deviation.
Spatial hearing: Sound localisation
(direction and distance), head-related transfer
functions (HRTF’s),
binaural models, precedence effect, phantom sources, Haas
effect, cocktail party effect, minimum audible
angle, influence of reflections.
Prerequisites:
Time- and frequency
analysis, statistics.
