Show Answers:

  1. 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
  2. Auditory Processing
    • hearing loss resulting from
    • damage to the processing centers of the brain
  3. conductive hearing loss
    • caused by damage to the
    • outer or middle ear, with the inner ear and cochlear intact
  4. FM system
    • personal amplification system
    • that can be used independently or with hearing aids
  5. immittance
    • describes the acoustic flow
    • of energy through the middle-ear space.
    • admittance=forward flow, impedance=oppositional energy against the flow
  6. 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
  7. 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
  8. prelingual hearing loss
    • occurs after birth but
    • before child has developed language
  9. sensorineural hearing loss
    • caused by damage to the
    • cochlea or the auditory nerve, with the outer/middle ear intact
  10. tympanometry
    • exams tympanic membrane movement or
    • vibration and graphs the results on
    • tympanogram
  11. 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
  12. aural habilitation
    • individualized intervention to achieve
    • fluent communication in a manual or oral modality
  13. Hearing Loss
    • condition in which a child
    • is unable to detect/distinguish the range of sounds normally available to the
    • human ear
  14. Evoked Auditory Potentials
    • EAPs measure the electrical response of
    • the auditory system to a sound stimulus
  15. Hard of Hearing
    • term to describe people
    • with hearing loss
  16. Hearing Loss
    • condition in which a child
    • is unable to detect/distinguish the range of sounds normally available to the
    • human ear
  17. Mixed Hearing Loss
    • caused by damage to both
    • the conductive and sensorineural mechanisms
  18. Otoacoustic Emissions
    • a measure of cochlear
    • function (specifically outer hair cells) and are considered a good indicator of
    • hearing acuity
  19. Postlingual Hearing Loss
    • occurs later in childhood
    • after language skill are well established
  20. Probe Microphone
    • real ear testing, an
    • objective computerized method of measuring hearing aid function in a childs ear
  21. Threshold
    • point at which a person can
    • begin to hear
  22. Labyrinthitis
    • affect the labrinth of the
    • inner ear in both the vestibular and cochlear mechanisms. short term infection
    • that is treated medically
  23. Noise-Induced Hearing Loss
    • caused by exposure to
    • occupational noise. second most
    • common cause of sensorineural hearing loss in adults
  24. Ototoxicity
    • a common cause of inner-ear
    • damage and sensorineural hearing loss.
    • damage caused by drugs
  25. Recruitment
    • reduced tolerance to
    • sounds- difficult to tolerate common loud noises
  26. 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.
  27. Hearing-Aid Orientation
    • counseling that focuses on
    • a client’s cognitive and emotional response to the hearing loss
  28. 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
  29. 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
  30. Presbycusis
    • hearing loss as a result of
    • aging
  31. 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
  32. Oral-Motor System
    refers to the physical structures and neuromuscular functions involved with both eating and speaking
  33. Oral-Motor Functions
    the strenth and coordination of the articulators
  34. Oral-Motor Muscular Tone
    the tension and posture of the articlators
  35. Oral-Motor Sensation
    sensitivity to taste, movement, and textures
  36. NICU
    neonatal intensive care unit
  37. penetration
    food or liquid enter the larynx which can cause choking and respiratory distress
  38. apiration
    food or liquid passes through larynx into lungs
  39. nasogastric tube
    • enteral feeding tube wich directs a liquid to the stomach through the nose
    • for short term treatmetn
  40. gastrostomy tube
    enteral feeding tube that send formula directly to the stomach
  41. 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
  42. Overselectivity
    children restrictive in taste, type, texture, or volume of food they will eat
  43. 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
  44. Conditioned Dysphagia
    a child may experience a traumatic event that results in resistance to eating
  45. Low Birth Weight
    are at great risk for feeding/swallowing disorders
  46. Prematurity

    • a metabolic disorder characterized by a deficient liver enzyme and elevated levels of amino acid phenylaline
  48. 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
  49. Gastroenterologist
    internists, radiologists, and other professionals that study and treat esophageal dysphagia resulting from the esophageal phase of swallowing
