SYLLABUS FOR HEARING SCIENCE

Course Number CD 5707 Instructor Robert de Jonge, Mar 58, 660-543-8809, [email protected], [email protected] Text Durrant & Lovrinic, Bases of Hearing Science 3rd Edition Exams One mid-term (multiple choice) and one final exam (short answer).

Paper: A paper is required. The purpose of the paper is for you to demonstate your knowledge of cochlear physiology. Basically, you should explain the functioning of the inner ear and VIII Nerve. Explain normal auditory functioning and, when appropriate, contrast it with changes that occur with disorders (Ménière's disease, acoustic neuroma, noise-induced hearing loss, etc.). Follow APA style.

Scope: The scope of the course is the structure and functioning of the auditory periphery. The primary emphasis is upon cochlear anatomy and physiology. In other words, we try to explain how the normal ear works, and how hearing disorders may change these processes. At the end of the course (second half) there is a review of physical concepts, acoustics, and the measurement of sound. This should help you to appreciate auditory processes.

Attendance: Class attendance policy is consistent with University policy. In addition, four absences are allowed for whatever reason (approved or not, at your discretion). Beyond this the final grade is reduced by 1/4 of a letter grade for each additional absence. The final grade will be increased by 1/4 for each of the allowed absences that is not used. Perfect attendance improves performance by one full letter grade.

TOPICS

I. Cochlear mechanics: The basic topic here involves basilar membrane movement, explaining how the cochlea carries out its frequency analysis, and how this relates to theories of hearing. Read chapter 5.

II. Cochlear electrophysiology: This section deals with the electrical events occurring in the inner ear, and the role they play in generating the 8th nerve response. This material is very basic to an understanding of brainstem audiometry. Read chapter 5.

III. Neural encoding: This section covers current thinking on how the auditory system (at the level of the 8th nerve and brainstem) encodes sensory information and processes it. Relations to such topics as binaural hearing, localization, etc. are discussed. Read chapter 6.

MIDTERM EXAMINATION

IV. A basic review of physical concepts: Physical concepts which relate to understanding how the ear behaves, acoustics, and the measurement of sound. This section is basically, "go at your own speed." Study questions are handed out for each chapter, which you can answer, and questions you may have are dealt with in class. After you have had a chance to work the problems, answer sheets will be handed out. At the end of each chapter, there will be a practice quiz, and answer sheets will also be available for these. Questions on the midterm will be similar to those on the problems and quizes. No surprises. Formal lecture will include major topics in each of the chapters. Read chapters 1, 2, and 3.

V. Anatomy of the ear: This is a general review of the anatomy, primarily of the inner ear, but also including the central auditory pathway. A HyperCard stack is available for drill. The matching part of the final will be based upon this tutorial. Read chapter 4.
