Investigators have determined that objective hearing screenings conducted during routine doctor visits are feasible and effective in detecting postnatal hearing loss. Currently, hearing screening is conducted at birth and before a child enters kindergarten leaving a large gap during which hearing loss can develop and remain undetected. If the initial screening fails to identify a hearing deficit or if hearing loss develops during the infant/toddler years, the child misses a significant period of language and cognitive development as well as sacrificing the opportunity for early intervention.
