Mechanism

Credit Hours: 2+1=3.

Course Instructor: Dr. Wahab Owolawi.

Course Description:

Study of the structure and function of the auditory and speech organs in the chain of communication.

Course Objectives:

1.  Students must know and understand the structure, functions and processes involved in the production and reception of speech and related sounds.

2.  Students should understand and explain at the end of the course the scientific relationship existing between the oral and auditory domain in the chain of communication.
