Conductive Hearing Loss

A form of deafness that results from a blockage of the ear canal or dysfunction of the ossicles or eardrum, usually through the buildup of fluid. Conductive hearing loss does not affect the auditory nerve and can usually be treated with antibiotics or ventilation tubes. Conductive hearing loss may be temporary or permanent.

Developmental Delay

Developmental delay is the term frequently used to identify children with delay in meeting developmental milestones in one or more streams of development. There is no consensus on the specific definition. Developmental delay is best viewed generically as a chief complaint rather than a diagnosis. A child suspected to have delays should always be assessed in each of the major streams of development: expressive and receptive language, including social communication; visual problem solving (nonverbal cognition); motor development; neurobehavioral development; and social-emotional development.

Early Hearing Detection and Intervention (EHDI)

Early Intervention

A specialized program to help a child immediately after detection. Time is of the essence because a child’s brain is programmed to learn language during the first 6 years of life – the first 3 years being the most critical. After this period, it is very difficult to acquire language and speech skills. Early intervention involves fitting children with hearing aids, providing counseling and support for parents, and teaching parents how to stimulate speech and language in their child.

Early Interventionist

A term that can be applied to many professionals who specialize in early intervention services for children with hearing loss. They are typically service providers with a specialty in listening and spoken language, such as speech-language pathologists, educators of the deaf, pediatric audiologists, or early childhood teachers or interventionists.
