Office Hours:  By appointment

Purpose/Description:
        This course will provide the student with an understanding of
various clinical  procedures in hearing screening, testing, and audiology.
Interpretation as well as the implications of the test results with regard
to diagnosis of the hearing impairment will be discussed.  Special problems
in hearing testing and information regarding an understanding of the causes
and types of hearing loss will also be provided.

Course Objectives:
        Upon successful completion  of this course, the student will be
able to:
- explain the types of hearing loss and degrees of hearing loss.
- explain the acoustic parameters of hearing.
- describe the anatomical, physiological, and pathological aspects of hearing.
- describe and perform basic hearing tests.
- describe the cochlear and retrocochlear site of lesion tests.
- describe the physiologic tests of hearing functions.
-accurately interpret, relate to the audiogram, and select special
audiological tests.
- develop an awareness of interpretation of the test results with regard to
diagnosis of
  the hearing impairment.
- explain the audiological implications in speech-language pathology (why
and what a speech pathologist know about audiology).

        Review for Final Learning Opportunity

Learning Opportunities & Requirements:
        There will be a total of two Learning Opportunities.  The Mid-term
Learning Opportunity will be held on ...  The final Learning Opportunity will be held on ...Each Learning Opportunity will account for 100 points.  If there is a change in the scheduling of the Learning Opportunity, it will be announced
by the instructor well in advance.
        Students are responsible for all materials, assignments, etc.
presented in the class by the instructor.  If you miss a class it is your
responsibility to make up for that class missed.

Grading:
        Final Class Grades will be determined by the number of points
obtained out of the possible 200 points.
        Grading Scale - 93 - 100% = A
                                85 -    92% = B
                                77 -    84% = C
                                60 -    76% = D
                                  0 -   59% = F

Pass/Fail Information:
        Graduate students have the option of registering on a pass/fail
basis for courses not included in their degree plan.  Courses on a
pass/fail basis may not be used for degree credit at SLU.  For credit
courses, a grade of P will be assigned only if the work is of at least C
quality.

Professional Standards:
        Students are expected to maintain professional standards of
behavior at all times when fulfilling course requirements.  Free
discussion, inquiry, and expression is encouraged in this class.  Classroom
behavior that interferes with either (a) the instructor's ability to
conduct the class or (b) the ability of students to benefit from the
instruction is not acceptable.  Examples may include routinely entering
class late or departing early; use of beepers/cellular phones, or other
electronic devices; repeatedly talking in class without being recognized;
talking while others are speaking; or arguing in a way that is perceived as
"crossing the civility line".  In the event of a situation where a student
legitimately needs to carry a beeper/cellular phone to class, prior notice
and approval of the instructor is required.
        Students must demonstrate proficiency in written composition as
written communication skills are basic to professional
communication/activities.  The written component of
examinations/assignments will be graded on correctness of usage, word
choice, spelling, punctuation, organization, neatness, as well as content.
        Students should consult the current catalogue for information
regarding the last day to drop or resign from the university without grade
penalty.  Students are responsible for completing required forms when they
find it necessary to discontinue university work prior to the end of the
semester.
       Tape recording of the lectures/class presentations is not permitted
unless prior permission to do so is taken from the instructor.
        Students will not be given make-up Learning Opportunities without a
valid written excuse for the absence.  If you are too sick and unable to
take a Learning Opportunity,  you should bring to me a note from your
physician that I can verify.  Without such a valid written note there can
be no excused absences from a Learning Opportunity.  Any student who is
excused from a Learning Opportunity will be able to take a make-up Learning
Opportunity until the time the original test is returned to the entire
class.  Once a test has been returned, make-ups are no longer possible.  In
such situations, alternate arrangements will be made on a case by case
basis.  The make-up Learning Opportunity will be in the form of oral exams.
