Hearing screening is an objective, physiological test procedure conducted for determining the likelihood of hearing loss. It provides a quick and cost effective way to separate people into two groups such as a pass group and a fail group. Pass group means that they have no hearing loss. Failed group means that they are in need of an in-depth evaluation by an audiologist and may also need follow-up care from other professionals. Hearing screening is performed from birth throughout the adult years when requested and when there is increased risk for hearing loss. It is also performed when it is mandated by state and local laws and practices.
According to Cal Bus & Prof Code § 2530.2(n) a "hearing screening" performed by a speech-language pathologist means a binary puretone screening at a preset intensity level for the purpose of determining if the screened individuals are in need of further medical or audiological evaluation.
