Communication Sciences and Disorders 330

COSD 330: Introduction to Audiology

Credit Hours: (3)

This course provides the anatomical, physiological, embryologic, developmental and acoustic foundations for the study of hearing screening procedures, hearing evaluation measures, and measures of hearing handicap. Students will learn about auditory disorders common to all ages and related medical and non-medical management approaches. Students will be exposed to basic hearing conservation and prevention of hearing loss. Selected hearing screening procedures and use of a wide range of clinical equipment, including amplification and sensory devices, will be addressed. Students cannot receive credit for this course if they have previously taken both COSD 331 and COSD 332.


Detailed Description of Content of the Course

The major topics addressed in this course are as follows:

  • Overview of the auditory system
  • Embryologic development of the ear and developmental stages of audition
  • Principles of acoustics
  • Anatomy and physiology of hearing
  • Hearing screening procedures and prevention of hearing handicap
  • Hearing evaluation procedures
  • Auditory disorders: characteristics and intervention approaches
  • Intervention approaches including medical/surgical, communication choices, and amplification and sensory devices

Discussion of hearing screening, hearing evaluation, and intervention approaches will emphasize the need for cultural sensitivity and awareness of the needs of a diverse client population.


Detailed Description of Conduct of Course

The course will consist of lectures, demonstrations, and labs related to hearing screening procedures.


Goals and Objectives of the Course

 Having successfully completed this course, students will be able:

  • To identify and describe different types of sound waves and acoustic characteristics of listening environments;
  • To identify and describe normal auditory system structure and function;
  • To identify appropriate prevention procedures and activities related to hearing loss;
  • To identify, describe, and select appropriate evaluation procedures, such as behavioral observations, non-standardized and standardized tests, and instrumental procedures; and
  • To identify and describe common auditory disorders and the typical intervention approaches to those disorders;


Assessment Measures

Grading will be based upon a combination of assessment measures, including in-class exams, lab assignments, short term papers, and a final examination.
