Hearing Evaluations

Pure-tone Audiometry
Hearing sensitivity or loss is quantified by using pure tones controlled by a dual-channel clinical audiometer and presented through earphones and a bone vibrator. Narrow-band masking noise is used when appropriate.

Speech Audiometry
Awareness of speech sensitivity, auditory discrimination of speech sounds, and hearing adequacy for everyday speech are evaluated with speech delivered through earphones and loudspeakers. Phonetically balanced work lists are presented to the patient via the clinical audiometer by monitored live voice or taped recordings.

Impedance Audiometry
The middle ear and the acoustic reflex are assessed with a clinical electroacoustic bridge, which can activate the acoustic reflex with either contralateral or ipsilateral test tones. Eardrum mobility and middle ear pressure are evaluated ipsilaterally with tympanometry.
