Terms & Glossary

Below is a list of terms frequently used in relation to individuals who are deaf or hard of hearing.

ABR (Auditory Brainstem Response):

an electrophysiologic hearing test during which electrodes are placed on the head; sound is presented through earphones while changes in brainwave activity are monitored. Sometimes called BAER (Brainstem Auditory Evoked Response).

Aided:

hearing levels obtained using hearing aids or a cochlear implant.

ASL (American Sign Language):

sign language system often used among deaf adults in the United States. ASL has its own grammatical structure that is different from English.

Audiologist:

healthcare professional with a Master's or Doctoral degree who is qualified to provide services in prevention, evaluation, and (re)habilitation of hearing loss and its associated communication disorder.

Audiommeter:

a specialized instrument used in the measurement of hearing.

Auditory nerve:

the eighth cranial nerve which transmits sound from the cochlea to the brain.

Cochlea:

the inner ear, consisting of bony and membrane chambers containing fluids and the sensory cells (hair cells) that send sound from the middle ear to the auditory nerve. Damage to the sensory cells in the inner ear is the most common cause of permanent hearing loss. The inner ear is physically connected to the balance mechanism.

Cued Speech:

a system of hand positions that a speaker uses near the face and neck, designed to help the listener differentiate between similar looking speech sounds.

dB (Decibel):

a unit of sound intensity that uses a base 10 logarithmic scale. Usually used in conjunction with some reference level.

dB HL (Decibels Hearing Level):

the notation used on an audiogram where "0 dB HL" represents average or typical hearing in humans.

ENT:

an ear, nose, and throat physician. Also called an otolaryngologist or an otorhinolaryngologist.

Feedback:

the squeal/whistle a hearing aid makes when amplified sound from the receiver reaches the microphone and is re-amplified.

Huggies:

a flexible plastic tubing and band device to help keep hearing aids on an infant or young child.

Huggie Aid:

a huggie that is attached to a length of flexible tubing and attached to a child's clothing to reduce the chance of hearing aids being lost.

Ossicles:

the three small bones of the middle ear (malleus, incus, and stapes) that transmit sound from the eardrum to the inner ear.

OAE (Otoacoustic Emissions):

an electrophysiologic hearing test that measures activity of the cochlea to help determine hearing levels.

Ottis media:

fluid in the middle ear space where there should be air. The fluid may either be clear, sterile fluid or yellowish green with a bacterial infection.

P.E. tubes:

pressure equalization tubes that are surgically placed in the eardrum by an otolaryngologist in order to allow chronic or recurring fluid to drain out of the middle ear.

Pidgin:

American Sign Language signs that are used in English word order.

Pinna:

the external cartilaginous portion of the ear that holds hearing aids or earrings.

Signed English:

sign language system that uses signs indicating tense and plurals in English word order (differs from American Sign Language).

Speech/Language Pathologist:

healthcare professional who has a Master's or Doctoral degree with expertise in providing services in prevention, evaluation, and rehabilitation of speech and language disorders.

Speech Reception Threshold:

the quietest sound intensity level where speech can be correctly identified.

Symmetrical hearing:

Early Hearing Detection and Intervention (EHDI) refers to the practice of screening every newborn for hearing loss prior to hospital discharge. Infants not passing the screening receive diagnostic evaluation before three months of age and, when necessary, are enrolled in early intervention programs by six months of age. All 50 states and the District of Columbia have Early Hearing Detection and Intervention (EHDI) laws or voluntary compliance programs that screen hearing.
