SPED 221
Introduction to Audiology
3 chs, Fall 2005

 

COURSE DESCRIPTION:

This course provides a general study of the science of hearing assessment. Instruction emphasis: terminology, physics of sound, anatomical and physiology of the hearing mechanism, audiologic evaluation and screening, and interpretation. Practical experience in hearing assessment is required.

RELATIONSHIP TO THE CIRCLE OF COURAGE:

The mission of the course is to empower participants with the audiological tools necessary to create a learning/working/recreational/communication environment that encourages a sense of belonging, independence, generosity, and mastery for individuals who experience hearing.

Belonging is an integral part of society. Hearing loss can result in a sense of non-participation and not belonging.  Participants will examine the physiologic, etiologic, and audiologic aspects of hearing loss and apply strategies that foster positive communication environments that encourage belonging between individuals with hearing loss and their communication partners.
Independence is a critical component for interacting successfully in society. Participants will examine audiologic, physiologic, and etiologic concepts of hearing loss and apply strategies that foster independence for individuals with hearing loss and their communication partners.
Generosity may be demonstrated through empathy, caring, concern, service, etc. Participants will examine audiologic, physiologic, and etiologic concepts of hearing loss and apply strategies that create positive communication climates between individuals with hearing loss and their communication partners.
Mastery is one of the keys for demonstrating preparedness, responsibility, competence, etc. Participants will examine etiologic, physiologic, and audiologic concepts of hearing loss and develop a mastery of these concepts in preparation to providing professional services to individuals with hearing loss and their communication partners.

COURSE INFORMATION

TEXT: Introduction to Audiology (with CD-ROM), 9/E , by Frederick N Martin & John Greer N Clark (2006)

• The text is an excellent introductory resource regarding the audiology profession which includes a CD.
• The text will be used extensively throughout this course and students are expected to read the material.

ATTENDANCE:

• Students are expected to be in attendance during scheduled class periods.  Grades are often a reflection of classroom attendance and participation.
• Students must be present during scheduled exam periods unless excused by the Dean of Students or the School Health Nurse or Physican provides a written note; otherwise the student will receive a failing grade for that test. Students must take the Final exam during the scheduled time period.  Lack of time to study, too busy, are not acceptable excuses.
• Schedule transportation arrangements so that you will be present for the Final.
• The student is responsible to make-up missed material when absent from class.  I would suggest that a student review notes from other students when absent from class.

INDIVIDUAL STUDY:

• If you are experiencing difficulty understanding the course material, please contact me so that I can assist you.
• There are no make-up tests or make-up assignments to raise grades. Students are encouraged to study well in advance for exams. Students perform much better on exams when students review material periodically rather than a day or two before the exam.  When assignments are late, the grade will be reduced by 10 points each day.
• It is recommended that students re-write class notes each day. This helps retain information and prepares one for the exams.
• Please read the text prior to class discussion. Do not delay in reading the assigned material well in advance of the exam. Students should review course material periodically throughout the semester rather than several days before an exam.  Assignments and exam dates are posted on the calendar so students can prepare in advance for exams and class discussion.
• The Virtual Tour of the Ear (http://www.augie.edu/perry/ear/ear.htm) has been developed as a resource and tool for this course.  Access and utilize the Virtual Tour of the Ear resources routinely throughout the course.

COMPUTER COMPETENCIES:

• access OLE, read mail, compose mail, forward mail, reply, delete mail, spell check mail, justify, create mailing lists, etc.
• access the Web, search, add bookmarks, view book marks, utilize the Augustana College Web online services and the Virtual Tour of the Ear, etc.
• access PowerPoint to complete the assignments
• upload and post assignment to your Geocities Web site.

BELIEFS/VALUES/ATTITUDES:

• Appropriate professional audiologic information and services play a vital role in the lives of individuals with hearing loss.  It is essential that professionals who provide services for individuals with hearing loss and their communication partners understand audiologic concepts and principles.

CLINIC:

• Students are required to obtain a minimum of 10 clock hours in the Diagnostic Rehabilitation Center or other appropriate settings approved by the instructor. These hours are supervised directly by ASHA certified personnel. These hours are necessary for students seeking certification for CED and ASHA.
