In general

Textbook:  William A. Yost (1994) Fundamentals of Hearing: An Introduction. San Diego CA: Academic Press.

Assignments: There will be 3 quizzes and one short paper, each having the same weight. The paper should be no more than 5 - 6 pages long (double spaced). The topic should be cleared in advance. You should also prepare for a 10 minute presentation of this same material to the class, at an evening meeting towards the end of the semester.
