Audiometry/Hearing Testing
Behavioral Audiometric Testing:
- Behavioral audiometric test techniques are used to assess a patient’s subjective responses to speech and frequency specific stimuli. Behavioral test methods vary depending on patient age and can be performed on patients beginning around the age of 8 months.
Immitance Testing:
- Tympanometry is an objective measure of middle ear function.
- Acoustic Reflexes are a measure of the middle ear reflex.
Otoacoustic Emissions Testing (OAEs):
- OAEs are an objective measure use to assess function of sensory cells within the cochlea.
Auditory Brainstem Response (ABR) Testing:
- An objective measure used to assess the transmission of sound from the auditory nerve to the lower brainstem. In our office, this measure is used as a means for rescreening infants who have failed their newborn hearing screening in the hospital.
