Sensory & Informatics Flashcards
Tinnitus
Abnormal ear or head sounds that aren’t produced by an external stim.
Conductive vs sensorineural hearing loss
C: stimuli isn’t transmitted. Mechanical part of the hearing.
(Earwax, otitis media, otosclerosis, fluid in inner ear, ruptured eardrum)
S:
(Damage to inner ear, ototoxic, loud noises, aging/Presbycusis, head injury)
nerve part of hearing. disorders that effect the inner ear, auditory nerve, or auditory pathways in the brain
Long-term exposure to loud noises puts clients at risk for…
Sensorineural hearing loss
Organ of corti
End organ of hearing in the cochlea. Transforms mechanical into neural activity
Otitis media
Infection of the middle ear (behind the eardrum)
Otalgia
Ear pain
Otorrhea
Ear drainage
Otosclerosis
Inherited disorder that causes hearing loss (likely starting in your 20s). Ear bones can’t vibrate fully. Hardening of TM.
Presbycusis
Age-related hearing loss
50% over age 70yo
Tympanoplasty
Surgery to repair ruptured eardrums (hole in the eardrum that isn’t healing)
Eustachian tube and its purpose
Connects middle ear to the mouth. Closed except during valsalva maneuvor/yawning.
Drains secretions from middle ear, protects middle ear, and ventilates (equalizes pressure).
Functional hearing loss
Caused by an emotional problem
Audiometry vs tempanogram
A: Measures hearing ability
T: measures eardrum
Hearing aids vs cochlear implants
Cochlear implants are surgically embedded for sensorineural deafness.
Hearing aid is more for conductive.
Avoid sound louder than a…
