-
air conduction
- way most sounds are
- delivered to the cochlea and auditory pathway, sound waves pass along the
- auditory canal and then as mechanical energy the the middle-ear space
-
Auditory Processing
Disorders
- hearing loss resulting from
- damage to the processing centers of the brain
-
conductive hearing loss
- caused by damage to the
- outer or middle ear, with the inner ear and cochlear intact
-
FM system
- personal amplification system
- that can be used independently or with hearing aids
-
immittance
- describes the acoustic flow
- of energy through the middle-ear space.
- admittance=forward flow, impedance=oppositional energy against the flow
-
otitis media
- middle ear dysfunction,
- most common cause of conductive hearing loss in kids, results from a viral or
- baterial infection of the middle-ear space
-
otoscopic examination
- allows audiologist to
- inspect external auditory canal and the tympanic membrane. purpose is to detect any abnormalities
- in theses structures and to ensure a clear external auditory canal prior to
- testing
-
prelingual hearing loss
- occurs after birth but
- before child has developed language
-
sensorineural hearing loss
- caused by damage to the
- cochlea or the auditory nerve, with the outer/middle ear intact
-
tympanometry
- exams tympanic membrane movement or
- vibration and graphs the results on
- tympanogram
-
audiometry
- pure tone testing, provides
- objective info about hearing acuity.
- it’s a behavioral measure b/c it relies on a child’s
- cooperation/participation by responding to tones
-
aural habilitation
- individualized intervention to achieve
- fluent communication in a manual or oral modality
-
Hearing Loss
- condition in which a child
- is unable to detect/distinguish the range of sounds normally available to the
- human ear
-
Evoked Auditory Potentials
- EAPs measure the electrical response of
- the auditory system to a sound stimulus
-
Hard of Hearing
- term to describe people
- with hearing loss
-
Hearing Loss
- condition in which a child
- is unable to detect/distinguish the range of sounds normally available to the
- human ear
-
Mixed Hearing Loss
- caused by damage to both
- the conductive and sensorineural mechanisms
-
Otoacoustic Emissions
- a measure of cochlear
- function (specifically outer hair cells) and are considered a good indicator of
- hearing acuity
-
Postlingual Hearing Loss
- occurs later in childhood
- after language skill are well established
-
Probe Microphone
Measurement
- real ear testing, an
- objective computerized method of measuring hearing aid function in a childs ear
-
Threshold
- point at which a person can
- begin to hear
-
Labyrinthitis
- affect the labrinth of the
- inner ear in both the vestibular and cochlear mechanisms. short term infection
- that is treated medically
-
Noise-Induced Hearing Loss
- caused by exposure to
- occupational noise. second most
- common cause of sensorineural hearing loss in adults
-
Ototoxicity
- a common cause of inner-ear
- damage and sensorineural hearing loss.
- damage caused by drugs
-
Recruitment
- reduced tolerance to
- sounds- difficult to tolerate common loud noises
-
Tinnitus
- a ringing, roaring,
- buzzing, or hissing sound in one or both ears. may be occasional frequent, intermittent, or continous. may be result of damage to ears, high
- blood pressure, stress, fatigue, excessive caffeine, etc.
-
Hearing-Aid Orientation
- counseling that focuses on
- a client’s cognitive and emotional response to the hearing loss
-
Meniere’s disease
- affect the labrinth of the
- inner ear in both the vestibular and coclear mechanisms. long-term disorder caused by an
- overproduction or underabsorption of endolymph
-
Otosclerosis
- condition in which abnormal
- bone growth develops around the ossicles. bone growth impedes movement of
- stapes, compromising the transmission of sound energy along ossicular
- plane. another cause of
- adult-onset conductive hearing loss
-
Presbycusis
- hearing loss as a result of
- aging
-
Signal-to-Noise Ration
(SNR) Loss
- explains why people
- complain that they can hear fine if people don’t mumble or no background
- noise. based on the relationship
- of a signal (voice of friend) to the noise in the environment. Signals become more difficult to
- discern as noise levels increase
-
Oral-Motor System
refers to the physical structures and neuromuscular functions involved with both eating and speaking
-
Oral-Motor Functions
the strenth and coordination of the articulators
-
Oral-Motor Muscular Tone
the tension and posture of the articlators
-
Oral-Motor Sensation
sensitivity to taste, movement, and textures
-
NICU
neonatal intensive care unit
-
penetration
food or liquid enter the larynx which can cause choking and respiratory distress
-
apiration
food or liquid passes through larynx into lungs
-
nasogastric tube
- enteral feeding tube wich directs a liquid to the stomach through the nose
- for short term treatmetn
-
gastrostomy tube
enteral feeding tube that send formula directly to the stomach
-
Cleft Palate
- an opening in their lip or palate
- require help achieving a good oral seal, as the hole in the palate creates a loss of pressure during sucking and can result in milk entereing the nasal cavity
-
Overselectivity
children restrictive in taste, type, texture, or volume of food they will eat
-
Reflux
gastric acid is regurgitated into the esophagus and pharynx. 40% infants regurgitate once daily. when its more frequent problems occur such as food aversion, loss of appetite, and malnutrition
-
Conditioned Dysphagia
a child may experience a traumatic event that results in resistance to eating
-
Low Birth Weight
are at great risk for feeding/swallowing disorders
-
Prematurity
when a child is born at or before 37 weeks of gestation
-
PKU
- phenylketonuria
- a metabolic disorder characterized by a deficient liver enzyme and elevated levels of amino acid phenylaline
-
Modified Barium Swallow
aka video swallow study, SLP works with radiologist and is one of only ways to look dircetly at the structures and functions as swallowing occurs
-
Gastroenterologist
internists, radiologists, and other professionals that study and treat esophageal dysphagia resulting from the esophageal phase of swallowing
