1 SLHS 267 Spring 2014 Title of Course: ACOUSTICS FOR THE SPEECH AND HEARING SCIENCES Day & Time 9-9:50 a.m. Room & Building: Instructor: Room: Chemistry 134 James Dean, AuD Office SLHS 523 Office Phone: jdean1@ .arizona.edu Office Hours: Thursday or by appointment TA hours will be announced in class and posted on D2L The information contained in the course syllabus, other than the grade and absence policies, may be subject to change with reasonable advance notice, as deemed appropriate by the instructor. ACOUSTICS FOR THE SPEECH AND HEARING SCIENCES COURSE DESCRIPTION This course will cover the basic principles of acoustics, especially with regard to speech and hearing sciences. 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 with some trigonometry. The required math courses for this class is math 111 and math 113. These math courses must be fully completed and cannot be taken concurrent with SLHS 267. 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 relationship between articulation and acoustics, prosodics and some speech technology. There will also be a review of the hearing mechanism s response to sound and auditory perception. Acknowledgement: Much of the content and materials of this course and syllabus were developed and created by Brad Story, Ph.D. Department of Speech, Language and Hearing Sciences, University of Arizona, Tucson AZ. RECOMMENDED TEXTBOOK: Used Copies Available at the UA Bookstore and On-Line. Speaks, C.E. (1999). Introduction to sound: Acoustics for the hearing and speech sciences, Third edition, Singular Publishing COURSE WEBSITE: At the instructor s discretion, most of the lecture notes (WebNotes) and handouts will be made available on the course website d2l.arizona.edu, FOR HELP GO TO: help.d2l.arizona.edu USEFUL REFERENCES Rossing, T.D.

2 COURSE REQUIREMENTS 1. ATTENDANCE: Students are expected to attend class regularly. Attendance may be taken periodically. Anyone who is chronically absent may have their grade lowered or be dropped from the class. 2. READING: All students are expected to read and study the WebNote assignments, course notes, study guides and any other material provided by the instructor. There is no required text book but the Speaks, C.E. (1999). Introduction to Sound: Acoustics for the Hearing and Speech Sciences, Third edition, Singular Publishing is highly recommended and can be obtained at a very reasonable cost through amazon.com 3. EXAMS: There will be three (3) exams and, three (3) quizzes given during the semester, and a final exam (see grades section below) 4. Homework: Homework will be assigned periodically. The expectation is approximately assignment during the semester. All must be handed in at the first class meeting after it has been assigned. Late will not be accepted and there will be no exceptions. Homework will be given 1 point if completed 0 not complete or not handed in. Students with Disabilities: If you anticipate barriers related to the format or requirements of this course, please meet with me so that we can discuss ways to ensure your full participation in the course. If you determine that disability-related accommodations are necessary, please register with Disability Resources ( ; and notify me of your eligibility for reasonable accommodations. We can then plan how to best coordinate your accommodations. GRADES: Course grades will be based on the sum of 3 sets of scores (total possible exam and quiz points = points (see below): Three in class exams (50 points each) = 150 points Three quizzes (15 points each) = 45 points Five pop quizzes (2 points each) = 10 points Final examination = 100 points Homework points (max 1 point each assignment) multiplied by the number of assignments given. GRADE REVISION POLICY: Excluding the final, students will have seven (7) days following the posting of their quiz or exam grade on D2L to review their quiz or exam and contest their grade. There will be no exceptions to the 7 day time limit for contesting a grade. Students will have 48 hours after the posting of the final exam grades on D2L to contest their grade. There is no pre-set grading curve for the class. Generally, a point accumulation of 90% of the total number of possible points will earn an A, 80% = B, and so forth. WebNotes and study guides on D2L are assigned readings. In many BUT NOT ALL cases pdf slide presentations are also available on D2L. The slide presentations on D2L are not exactly the same as the lectures slides for class and this is by design to encourage regular class attendance. You are responsible for reading all materials provided in class or posted on D2L. Questions on exams and quizzes will be drawn from lectures, the assigned and provided readings and not strictly from the lectures slides. 2
