Diagnostic Procedures of the Ears and Hearing
Audiometry
Use audiometer
Measure hearing acuity
Monaural Testing
Involve one ear
Compare with binaural testing
Audiological Evaluation
Measurement of ability to hear
Understand speech sounds on pitch & loudness
Result best sound-treated with earphones
Weber and Rinne Tests
Use tuning fork
To differentiate conductive & sensorineural hearing losses
Tuning fork vibration determine hearing ability
Tympanometry
Use of air pressure to test disorder at middle ear
Middle ear fluid buildup
Eustachian tube obstruction
Evaluate conductive hearing loss
Binaural Testing
Involve both ears
Compare with monaural testing
Hertz
Measure of sound frequency
Determine how high/low pitch
Acoustic Reflectometry
Measure sound reflected from eardrum
Way knowing how much fluid in the middle ear
To diagnose otitis media
Otoscope
Instrument use to examine external ear canal
