Implant used to stimulate the cochlea hair cell’s, enabling the person to hear
Cochlear implant
What are 2 types of hearing aids?
Behind the ear, in the canal
Tip the person back and turn their head quickly to the side; if it causes eye twitching or dizziness, vertigo is present
Dix Hallpike
Putting warm or cool air into the ear canal; can measure the movement of the eye. Dix Hallpike is also involved.
VNG
Tests if the VOR is intact
Rotary chair
Tests visual system, somatosensory system, and vestibular system
Posturography
Standing up and closing your eyes and trying to test vestibular sense
Romberg
Branch of science that studies hearing, balance, and related disorders.
Audiology
Treats those with hearing loss and proactively prevent related damage
Audiologist
Can affect speech and language development, academics, social, and emotional well-being and communication; can be temporary or permanent
Hearing loss
Hearing loss caused by noise, age-related, toxins, etc.
Noise induced hearing loss
Generalist, works in a variety of settings
Clinical audiology
Specialty of fitting hearing aids and other assistive devices; will do audiometric testing to detect types of hearing loss
Dispensing audiology
Services focus on diagnostics to determine the location and cause of hearing disorders; deals with vestibular issues
Medical audiology
Monitors the surgery if the surgery is close to the auditory nerve
Intraoperative monitoring
Rules out any type of hearing loss after birth
Newborn screening program
Deals with vestibular disorders and concussion programs
Vestibular audiology
Monitor levels of equipment and background noise and educate workers on hearing protection
Industrial audiology
Diagnostic procedure with children; serve on cochlear implant teams
Pediatric audiology
Responsible for the identification and referral of children with hearing/ear related issues; manages and conducts hearing screening programs
Education audiology
Permanent hearing loss due to damaged hair cells in the cochlea
Sensorineural hearing loss
Transforms physical energy into chemical and electrical activity in brain neurons
Hearing mechanism
What is in the outer ear?
Pinna, typanic membrane, ear canal
What is included in the inner ear?
Cochlea, semicircular canals
What is included in the middle ear?
Ossicles, eustachian tube
Collects sound waves and directs them to the tympanic membrane
Outer ear
Transmits vibrations to the oval window
Middle ear
Fluid motion in cochlea stimulates hair cells that send a neural impulse to the brain
Inner ear
Sends electrical currents from cochlea to auditory cortex in temporal lobes
Auditory nervous system
Most common type of hearing loss
Noise sensitivity impairment
Damage to the outer or middle ear
Conductive
Determines the nature and extent of the hearing impairment
Hearing assessment
Electrode placed on the head, reads if the brain is responding to stimuli
Auditory brainstem response
What type of assessment is in the newborn hearing screening?
Auditory brainstem response
Used to measure hearing thresholds at multiple frequencies for air and bone sound conduction
Pure tone audiometry
Uses speech signals presented at different decibels; assesses how hearing disorder affects normal communication
Speech audiometry
What are the 3 main areas of emphasis on auditory rehabilitation?
understanding the individual, professional support and counseling, amplification and successful communication
Using visual cues from the speaker’s mouth and face
Lipreading
Uses the speaker’s nonverbal communication and clues from context
Speech reading
