BOA

Behavioral Observation Audiometry (BOA) is a specialized hearing assessment designed for newborns and very young infants, usually below six months of age. Since children at this stage are unable to provide active feedback, BOA relies on observing their natural reactions to various sounds. Audiologists watch for subtle behavioral changes—like eye widening, blinking, startling, or alterations in sucking behavior—in response to auditory stimuli. These responses help indicate whether the child can detect sound and at what volume. BOA plays a crucial role in early hearing detection, ensuring timely intervention if any hearing impairment is present.
