Physics 382
Acoustics I: Sounds and Sources
Fall 2003 - Course syllabus
Text:
The Master Handbook of Acoustics, 4th ed. F. Alton Everest
(McGraw-Hill, 2001)
This text provides a general-interest introduction into a some
of the basics of acoustics, and a great many applications from speaker
building to creating a listening room in your home.
An Introduction to Acoustics, Daniel A. Russell (available as
classroom handouts)
This is a more traditional academic textbook to provide a solid
theoretical spine to the work we'll do. The satisfaction of understanding
the foundation thoroughly is part of an upper-level physics course.
Other resources (check the library! some
are on reserve):
Fundamentals of Acoustics, 4th ed. Kinsler, Frey, Coppens, Sanders
(J. Wiley, 2000)
The Physics of Musical Instruments, 2nd ed. Neville
H. Fletcher and Thomas D. Rossing (Springer-Verlag, 1998)
Matlab is available in computer labs to work on homework problems. We
will use this programming environment to "flesh out" equations, process
data, and analyze/synthesize signals.

Course Description
The course is a survey of the study of acoustics,
with fundamentals concepts and principles at the heart of sound
and vibration. The course will be somewhat unconventional, in
several ways:
- The first week will be a quick sweep of typical acoustics applications
and topics. Following that, we'll look deeper into each area.
- Some major topics will be introduced through problems -- not
homework exercises, but real-world problems that require us to identify
key phenomena, model these phenomena in simpler physical ideas, and
understand the physics behind the models.
- Much of the work will be carried out in groups comprised of
randomly assigned classmates. Individual understanding will
be demonstrated on exams, but assignments and discovery will happen
in a team context.
The last two points are part of Problem-Based Learning,
and approach to course organization that stresses case studies as
motivation for inquiry, and student initiative in learning.

The content of this course wraps around in a spiral fashion:
We'll touch on topics in one area, circle around to another area, and
another area, and so on...
Evaluation and Grading
The final grade will be calculated based
on the following components:
- Homework 40%
- Topic Reports 25%
- Midterm Exam 15%
- Final Exam 20%
Homework Frequent problem
sets will be assigned. Do these habitually and honestly.
Studying together is encouraged, but as in any team situation, you'll
learn best by active and thoughtful participation. Turn in your
own work - work that reflects your own understanding. Show your
work, explain your claims, and turn in any computer code (including
Matlab, Maple, etc.) Homework that is late by more than
one week is not accepted.
Topic Reports There are
6 topics that will be tackled in the context of PBL. Each group
will investigate these topics, develop a recommendation, and submit
a report. Details on the report requirements will be given in a
separate
page .
Midterm Exam This is a take-home test that will be given
after Week 5. It is due Wednesday of Week 6. This
has been changed to an hour-long, in-class exam on Friday of Week 6.
More details will follow.
Final Exam. The final exam will
be given at the determined final exam time, and will cover the salient
material from the entire course. This is intended to be an opportunity
for you to pause and synthesize ideas.
Policies and Procedures
Motivated by the goals and objectives
of the course, these policies and procedures are intended to foster a
safe and constructive environment
for learning physics. To maintain this kind of environment,
the instructor reserves the right to take any reasonable action sanctioned
by University policy, including but not limited to failure on an assignment
or withdrawal of student from the course. Disruptive behavior (including
excessive talking), ethnic or racial discrimination, or sexual harassment
will not be tolerated. Please turn off cell
phones and pagers.
Academic Integrity.
I expect the highest level of academic integrity from students.
The exams and homework are designed to reflect individual understanding
and skill. They are not collaborative efforts. Plagiarism (the
use of another's ideas as your own) is not acceptable. Evidence
of cheating, or anything contradicting these policies, may result
in a score of zero on the assignment or other action at my discretion.
Please know and practice the Kettering University Code of Academic
Integrity, found in the student handbook.
Office Hours. I will be in
my office at posted scheduled times, except under extreme circumstances.
However, please feel free to visit me in my office whenever my
door is open. A third alternative is a prearranged meeting set up
in class, via email, or by calling my office.
Regular and prompt attendance and active
class participation are so important to this course that if you
miss more than two class periods, I reserve the right to withdraw
you from the class roll.
Evaluation. Grading will
emphasize understanding. Therefore, the process of solution may
often be awarded partial and significant credit, and minutiae such
as arithmetic errors carry less weight in scoring. Again, practice
on homework problems will help establish habits that will score higher:
solutions must demonstrate clear thinking. Appeals are welcome if you
feel that a quiz, test, or exam has not been graded fairly. Extra credit
may be awarded if you discover a significant error on a midterm, or
final exam. Prepare your argument in writing, either by prose explanation
or clearly-worked solution, then visit me personally.
