Course description
This course will cover the basic principles of acoustics, especially with regard to speech and hearing
science. The target audience is students majoring in Speech, Language, and Hearing Sciences. The course
may also be of interest to students in Music, Linguistics, and Engineering. The mathematical demands of
the course will be at the level of college algebra. The first part of the course will address descriptions of
sound, simple harmonic motion, pressure waves, decibels, complex waves, resonance, and sound transmission.
The second part will focus on the acoustics of speech production, the relation of acoustics to articulation,
spectrographic analysis, and speech synthesis.

Course requirements and grading policies
• Scientific calculator: You will need a basic scientific calculator with logarithms and trigonometric functions. You should be able to find one for around ten dollars. You will not be allowed to use a calculator
app on a smartphone, iPad, or laptop during quizzes and exams.
• Reading: All students are expected to read and study the textbook/course notes and any other material
provided by the instructor.
• Homework assignments: Homework will be assigned to coincide with many of the lectures. These assignments will be collected and are given 1 point if completed and a 1/2 point if more than half the
assignment is completed. At the end of the semester the three lowest homework scores will be dropped
and the remaining homework scores will be normalized to 50 points, regardless of the number of assignments given. Late homework assignments will not be accepted (that’s why the three lowest are
dropped!).
• Quizzes and Exams: There will be two quizzes given throughout the semester. These will be taken either
during the first or last 25 minutes of a class period, and will be worth 25 points each. Three exams will
also be given during the semester and will be taken during either the first or last hour of a class period.
Each exam will be worth 50 points. Quizzes and exams may include information from the notes, lectures,
or any other material provided or assigned by the instructor for the topics covered.
• Reviews of Journal Articles: All students are required to turn in reviews of two articles published in the
Journal of the Acoustical Society of America. The first review will be of an article published prior to
1960 and is due on October 30. The second review should be based on an article published after 1960
and will be due on December 4. More details will be given in class. Each review should be about 2-3
pages and is worth 15 points. They will be graded on content, clarity of writing, as well as punctuation,
spelling, etc.
• Grading policies: Course grades will be based on the sum of five sets of scores (maximum pts = 380):
–
–
–
–
–
Three (1) hour examinations (50 points, each) = 150 points
Two quizzes (25 points each) = 50 points
Homework = 50 points
Final examination = 100 points
Article reviews = 30 points
Generally, a point accumulation of 90% of the maximum number of points (380) will earn an “A”, 80% =
“B”, and so forth.
• Regrading policies: There is no regrading unless there is clearly an objective grading error.
Class Policies
1. Absences: Students are expected to attend class unless there is an unavoidable circumstance such as
illness or emergency. Attendance may be taken periodically. Anyone who is chronically absent may have
their grade lowered or be dropped from the class. All holidays or special events observed by organized
religions will be honored for those students who show affiliation with that particular religion. Absences
pre-approved by the UA Dean of Students (or Dean designee) will be honored.

2. Electronic devices: Please turn off or silence all cell phones and other electronic devices during class.
If you must take a call for emergency purposes, please do so by placing your phone’s ringer on silent or
vibrate and leave the room to answer your phone.
3. Incomplete grade policy: Incomplete grades will be given ONLY in special circumstances as outlined in
the university’s policy. See: http://catalog.arizona.edu/2006-07/policies/grade.htm
4. Threatening Behavior: Threatening behavior is prohibited at the University of Arizona. “Threatening
behavior” means any statement, communication, conduct or gesture, including those in written form,
directed toward any member of the University community that causes a reasonable apprehension of
physical harm to a person or property. See http://policy.web.arizona.edu/threatening-behavior-students
for the University’s policy.
5. Accessibility and Accommodations: It is the University’s goal that learning experiences be as accessible
as possible. If you anticipate or experience physical or academic barriers based on disability, please
let me know immediately so that we can discuss options. You are also welcome to contact Disability
Resources (520-621-3268) to establish reasonable accommodations.
6. Academic Integrity and Plagiarism: All students are expected to know and abide by the Code of Academic Integrity. The complete code can be found at http://deanofstudents.arizona.edu/codeofacademicintegrity.
All credit will be forfeited for any academic work completed for this class that violates the code.
7. Statement of Copyrighted Materials: Students are advised that all lecture notes, lectures, study guides
and other course materials disseminated by the instructor to the students, whether in class or online, are original materials and as such reflect intellectual property of the instructor or author of those
works. All readings, study guides, lecture notes and handouts are intended for individual use by the
student. Students may not distribute or reproduce these materials for commercial purposes without
the express written consent of the instructor. Students who sell or distribute these materials for any
use other than their own are in violation of the University’s Intellectual Property Policy (available at
http://www.ott.arizona.edu/uploads/ip_policy.pdf). Violations of the instructors copyright may result in
course sanctions and violate the Code of Academic Integrity.
8. Change in Syllabus: This syllabus is a tentative document and is subject to change with reasonable
advance notice. The policies on grading and absences will NOT change.
