EE417: Acoustics and Audio Engineering
Prof. Robert C. Maher
529 Cobleigh Hall (southwest corner of 5th floor)
PHYS 212 GENERAL AND MODERN PHYSICS II Textbooks and Materials
- Ballou, Glen, Handbook for Sound Engineers, 3rd ed., Focal Press/Elsevier, 2002.
- Kinsler, Lawrence E., Frey, Austin R., Coppens, Alan B., and Sanders, James V., Fundamentals of Acoustics, 4th ed., Wiley & Sons, 1999.
The students obtain sufficient background and technical knowledge to understand contemporary issues in audio engineering.
At the conclusion of EE 417, students will be able to:
- Understand the linear acoustic wave equation and explain the relationship between pressure and particle velocity for plane waves and spherical waves.
- Calculate and interpret the near-field and far-field response of a circular piston radiator mounted in an infinite baffle.
- Explain the basic physiology of the human hearing system and elementary psychoacoustical principles (e.g., sensitivity as a function of frequency, simultaneous masking, and difference limens).
- Use geometrical measurements and material properties to calculate Sabine reverberation time for a room.
- Explain the basic operation of dynamic (moving-coil) loudspeakers and condenser (capacitive) microphones.
- Understand the principles of recording studio signal flow.
- Discuss the strengths and weaknesses of modern perceptual audio coders such as MP3.
- Describe the attributes of CD, DVD, and DAT storage media.

|Homework, Concerts, and Written Report:||25%||
→ Homework will be required periodically. Homework is due on the due date at the
BEGINNING of class. No late homework will be accepted.
→ Written in-class exam given late in September.
→ Written in-class exam given in mid November.
→ The final exam is:
Grade guarantee: course letter grades may be higher (but will not be lower) than
indicated by the following scale:A- = 90%
B- = 80%
C- = 70%
D = 60%
F = 59%A grade of F will also be given automatically if a midterm and/or final exam is not taken, regardless of the student's aggregate score total.
- All students must have an electronic mail address listed with the MSU My Info system. Announcements and reminders for EE417 will be sent occasionally via email.
- You are responsible for all material covered in class and in the textbook reading assignments.
- Homework problems will sometimes require Matlab or an equivalent computer tool. Matlab is available in the ECE computer labs.
- There will probably be several field trips scheduled during the semester. Although it is not reasonable for me to make the field trips mandatory, I do expect the students to take advantage of all learning opportunities provided in the course.
- Homework and exams must be prepared individually. Submitting the work of others without clear attribution is dishonest and grounds for dismissal from the course.
- Late submissions of assignments (homework and reports) will not be accepted. Plan ahead and notify the instructor prior to justifiable absences, or if a bona fide emergency prevented you from attending class.
