Terms in this set (38)
family centered approach
an intervention approach that places the family as being central to a child's well-being and acknowledges that emotional, social, and developmental support are integral components of the aural rehabilitation plan
universal newborn hearing screening (UNHS)
the application of rapid and simple audiological tests, typically with automated auditory brainstem response (A-ABR) and otoacoustic emission (OAE) measures, to all newborn babies prior to their leaving the hospital with the goal of identifying those babies who require further testing; also called neonatal hearing screening
AKA the well-baby nursery, is a hospital unit designed to provide care for healthy newborn infants
early hearing detection and intervention (EDHI) Act
provides federal funds for states to develop infant hearing screening and intervention programs, includes provisions to support hearing screening and when appropriate, full diagnostic evaluation of all newborns and provides for enrollment into early intervention programs and promotes culturally sensitive family support services.
occurs when a baby does not have a hearing loss but fails the screening test
middle ear effusion
the exudation of fluid from membranous tissue into the middle ear cavity
occurs when a nervous system function has failed to develop as rapidly as usual
occurs when a baby has hearing loss but passes the screening test
joint community on infant hearing (JNIH)
a committee comprising professionals from audiology, otolaryngology, pediatrics, education, and speech and language pathology that proffers position papers and establishes practice standards for the early identification of and the follow-up care for infants and toddlers who have congenital hearing loss
a numeric value between 1 and 10 assigned to newborns to describe their physcial status at birth
auditory brainstem response (ABR)
an auditory evoked potential that originates from the eight cranial nerve and auditory brainstem structures. The electrophysiological record consists of 5 to 7 peaks, which represent the neural functioning of the auditory pathway.
auditory evoked potential (AEP)
an electrophysiological response to sound, distinguished by latency
dB nHL (decibels normalized hearing level)
a decibel notation that is referenced to behavioral thresholds of a group of persons with normal hearing and is used to describe the intensity level of stimuli used in evoked potential audiometry
auditory steady state evoked potentials (ASSEP)
elicited by amplitude-modulated pure tones (or noise), and provide frequency-specific information; they may be used to determine thresholds that exceed 90-dB nHL.
automated auditory brainstem response (A-ABR)
a screening method to measure the auditory brainstem response in which recording parameters are computer-controlled and detection of the response is determined by computer-based algorithms
otoacoustic emissions (OAEs)
low-level sound emitted spontaneously by the cochlea on presentation of an auditory stimulus
outer hair cells
reside in the organ of Corti and amplify vibrations of sound entering from the middle ear and appear to potentiate the sensitivity of the inner hair cells
-amplify sounds entering the inner ear from the middle ear
distortion product otoacoustic emission (DPOAE)
the acoustic energy created by stimulating the ear with 2 simultaneous pure tones, which results in energy created at several frequencies that are combinations of the two pure tones.
transient evoked otoacoustic emission (TEOAE)
a means to access the integrity and function of the outer hair cells by presenting brief clicks. The low-level acoustic response emitted by the cochlea is measured.
behavioral/observational audiometry (BAO)
a method of testing a child's hearing in which the tester presents a sound stimulus and observes the child's behavior for change
acoustic startle response
a baby's response to unexpected loud sound and is typified by a head jerk and out-flung arms
visual reinforcement audiometry (VRA)
a method of audiometric testing for young children that entails providing an acoustic signal and reinforcing a head turn with a light stimulus or an activated and illuminated toy reinforcement
a new or modified response to a previously neutral stimulus
conditioned play audiometry (CPA)
a method of testing children 2 and 1/2 years and older in which the child is trained to perform a task in response to presentation of a sound
speech detection threshold (SDT)
the level at which speech is just audible
a hearing loss of unknown origin
a member of the herpes virus family
a condition during pregnancy that is characterized by hypertension, or a sharp spike in blood pressure, and edema, or swelling of the hands and feet as a result of excessive body fluid
refers to a deficiency or absence of oxygen in the body tissues
an abnormally small head due to a failure of the brain to grow
computed tomography (CT) scan
creates a series of detailed pictures of areas inside of the body, taken from different angles or planes. The pictures are created by a computer that is linked to an x-ray machine.
central auditory processing disorder (CAPD)
an inability to differentiate, recognize and understand sounds. this inability is not due to either hearing loss or cognitive impairment
a condition where the patient has a pure-tone audiogram that shows any degree of hearing loss, from mild to profound, and shows normal OAEs. ABRs are wither absent or degraded, and word discrimination is reduced disproportionately to the pure-tone loss.
inner hair cells
a single row of auditory receptor cells in the organ of corti that are in synaptic connect with the fibers of the auditory nerve.
- convert vibrations traversing through the cochlea into electrical signals
family systems theory
describes how members of a family are interconnected, and how their patterns of communication and interaction affect one another
