Exam 1 Study Guide Topics: 1. Anatomy and Physiology of the Peripheral Auditory System 2. dB Concept: Why absolute intensity measurement cannot be used in clinical audiology? What is audiometric zero? Why audiometers are calibrated in dB HL rather than dB SPL? 3. Audiogram Interpretation: Degree and type of hearing loss Masking Audiogram correlation with speech audiometry (SAT, SRT and SRS) 4. Immittance Audiometry: Basic instrumentation Evaluation and interpretation Acoustic reflex threshold 5. Otoacoustic Emissions and Auditory Brainstem Responses: OAE: pass or fail ABR: Threshold tracking and differential diagnosis 6. Hearing Disorders and Audiological Test Battery Outer ear disorders Middle ear disorders Inner ear disorders: 7. Pediatric Audiology Why early identification of persons with hearing impairment is important? Importance of newborn hearing screening When and how we perform behavioral audiometry, visual reinforcement audiometry and conditioned (play) audiometry
