Students read a description of audiograms. They review audiograms representing various degrees and types of hearing loss.

Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.

The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.
