Lecture List

Description

  The Acoustics of Speech and Hearing is an H-Level graduate course that averages 4 hours of lecture/recitation, 1 hour of lab, 7 hours of self study per week. The course reviews the physical processes involved in the production, propagation and reception of human speech with particular attention to how the the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Particular attention is paid to (1) the acoustic cues used in determining the direction of a sound source, (2) the acoustic and mechanical mechanisms involved in speech production and (3) the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear.

General Information
The class meets for two 1.5 hour lectures and one 1-hour recitation session each week with two take home laboratory sessions scheduled during the semester. There are 15 written assignments during the year consisting of problem sets (11 throughout the term), lab reports (2 throughout the term) and two take-home exams (a mid-term and a final). There are also 5 paper discussion sessions in which everyone is expected to participate.

Grading: 15% of the final grade is based on homework, 15% is based on participation in class and in discussions of relevant literature, 10% is based on the two lab reports, 60% is based on the mid-term and final exam. Students are encouraged to seek the help of the teaching staff in performing the homeworks.

Who Should Take This Course
The Acoustics of Speech and Hearing Course is open to beginning graduate students and upper level undergraduates who have had two semesters of college-level physics (or equivalent) and integral calculus. Past students have included Physics, EE and ME seniors and graduate students as well as grad students from HST and the Media Lab. The course is recommended for all students entering the Speech and Hearing BioScience and Technology Program.

Where & When

Lectures are held Tuesdays (T) and Thursdays (R) from 1PM - 2:30PM in 34-301 at MIT

Recitations are on Wednesdays (W) from Noon -1 PM in 34-304 at MIT

Laboratory Sessions are computer-based take-home exercises.

Text Books & Library Reserves

The recomended but not required book for the course is:
"The Speech Chain: The physics and biology of spoken speech" by P.B. Denes & E.N. Pinson, WH Freeman 2nd ed. 1993, ISBN 0-7167-2344-1.
This text is written for non-engineers; it contains a clear basic description of the physiologic and physical processes involved in speech production, transmission, reception and recognition. This book may be purchased for $27 from Amazon.com or Barnes & Noble.com. 

A text/workbook that covers some of the course material in more detail is;
"The Fundamentals of Sounds with Applications to Speech and Hearing" by WJ Mullin, WJ Gerace.JP Mestre and SL Velleman, Published by Allyn and Bacon, Boston, 2003, ISBN 0-205-37087-X . This book is available from Barnes and Noble (www.bn.com) for $67 new or $20 to $35 used.

Other more detailed and engineering oriented texts found in the Barker Engineering Libraries may be useful, including:

"Fundamentals of Acoustics" by Kinsler, Frey, Coppens and Saunders, Academic Press 1982.

"Acoustics" by Leo Beranek, American Institute of Physics 1986.

"Acoustic Phonetics" by Ken Stevens, MIT Press 1998.

"Signals and System for Speech and Hearing" by Stuart Rosen & Peter Howell , Academic Press 1991.

A book that gives a more quantitative view point of acoustics and speech and hearing is
"Acoustic Systems in Biology" by Neville Fletcher, Oxford University Press 1992.

A more thorough treatment of the hearing process is
"Fundamentals of Hearing" by William Yost, 3rd edition, Academic Press, 1994.
