Behavioral Observation Audiometry
Assesses hearing acuity using unconditioned responses to sound (i.e., reflexive and orienting behaviors). Appropriate for children from birth through age 7 months.
The infant is observed for changes in behavior after presentation of an acoustic stimulus in the soundfield (through speakers) or with Hear-Kit Noisemakers.
This screening test provides information about age-appropriateness of an infant's response to supra-threshold sound. Can rule out significant hearing loss.
This method relies solely on the audiologist's observations to determine when a response to sound has occurred. Cannot be used to define auditory thresholds.
