CDS 287 Psychoacoustic Science (Reg. #467593)
Instructors: Richard Salvi (829 2001 x13, email: salvi@buffalo.edu)
TA:
U-Cheng Leong (uleong@acsu.buffalo.edu) 215 Parker Hall
Location: Room: 4 Diefendorf
Course Content:
Psychoacoustics is the study of the psychological response (hearing) of a listener
to acoustic stimuli (sound). The first part
of the course covers some the basic characteristics of sound and sound measurement and
analysis. The second part provides a brief
overview of how sound is transmitted through air into the external ear, then through the
middle and finally into to the inner ear (cochlea). The
inner is responsible for converting mechanical vibration into a pattern of neural
activity. The third part of the course is
concerned with the basic performance characteristics of normal listeners. How does hearing performance change when the
duration of a signal increases or decreases? How
does a listener use sound information to determine the location of a sound source in space
(localization)? How does hearing performance
change when there is pathology of the middle ear? What
changes in hearing occur after a listener is exposed to high levels of noise that can
damage the inner ear? How do pathologies in
the central auditory brain affect hearing performance?

Grades:
The material covered in the lectures will come from the assigned text, lecture
notes and classroom presentations. Four
exams, each consisting of approximately 50 questions, will be given during the semester. The final grade will be based on the average of
the four tests. Each exam is given equal weight. Grades
will be based on a curve or normal distribution. The only valid reasons for missing an
exam are medical reasons and family emergencies.
In the event that a student is unable to take an exam at the scheduled time, the
student should contact the instructor immediately.
