Auditory Brainstem Response Audiometry (ABR)

Purpose:
Assesses auditory function from cochlea level up to the brainstem.

Age:
Appropriate for individuals from birth through adulthood.

Procedure:
The auditory system is stimulated by a brief acoustic signal via air or bone conduction. The resulting neuro-electric activity is recorded by surface electrodes placed on the head. The response is assessed based on the identification of component waves, their morphology and the measurement of absolute and interwave latencies compared to normative data collected via various previous studies and normal groups of subjects.

Results:
Provides ear-specific information and some frequency-specific information about hearing acuity within 5-10 dB of behavioral thresholds. Can also detect cochlea and/ or neural pathologies.

Limitations:
Requires individuals to be in sleep state. Some infants and young children may require sedation.
