combination of conductive and sensorineural hearing loss; parts of the outer middle and inner ear are affected.
Sensorineural Hearing Loss
affects the inner ear and beyond.
Conductive Hearing Loss
affects the outer and middle ear.
test measured based on patients response.
test measured without use of patient response thus they are extremely reliable.
Behavior Observation Audiometry
this is a type of subjective test where a patients behavior is observed in response to sound; not very reliable but often a good tool for counseling parents.
Visual Reinforcement Audiometry
this is a type of subjective test that is used for clients under age 3; child looks for toy to light up when they hear a sound.
this is a type of subjective test that allows the child to participate in some sort of play task when they hear a sound.
a type of objective test that measures middle ear function; Tympanometry
Auditory Brainstem Response
a type of objective test which test the Auditory nerves response to sound stimuli.
Oto Acoustic Emissions
an objective test used to measure function of the cochlea; usually correlates to normal hearing.
Speech Recognition Test
used for amplification purposes, to track progress over time, or determine need for auditory training.
Style of Hearing Aid
describes what a device looks like on the outside.
Type of Hearing Aid
describe how the device operates or what kind of technology is used in it.
Body Style Aids
worn usually around the neck with small ear phones; used for profound hearing loss.
hearing aid necessary for someone with severe to profound hearing loss.
hearing aid that can be fitted for clients with no greater than sever hearing loss.
hearing aid that can be fitted for clients with mild or moderate hearing loss.
hearing aid that can be fitted for client's with no greater than severe hearing loss.
Open Ear Fit
with this style of hearing aid the occlusion effect is totally eliminated; no feedback is present; contains feedback cancellation.
this type of hearing aid has a physical amplifier; a vibrating diaphragm causes amplification.
this type of hearing aid has a physical amplifier and can be programmed by a computer.
this type of hearing aid contains a digital amplifier that is computerized and operate via microchip.
is a surgically implanted device that acts to replaced damaged hair cells in the cochlea.
Underlying Purpose of a Cochlear Implant
to allow a person to hear the sounds of speech for the purpose of listening and developing spoken language.
therapy for a patient who developed speech and language before their hearing loss occurred.
therapy for a patient who never developed speech and language before their hearing loss.
What are the goals of AR?
to alleviate difficulty related to hearing loss and minimize consequences.
FDA Criteria for 12 months - 2 years
-profound SNHL binaurally. -lack of progress with auditory skills development -realistic expectations -family/caregiver supportive and proactive in rehab.
FDA Criteria for 2-17 years
-severe to profound SNHL binaurally -limited hearing aid benefit -lack of progress with auditory skills development
FDA Criteria for 18 years +
-severe to profound SNHL binaurally -pre or post linguistic onset -limited hearing aid benefit -sentence recognition scores which are less than 50% in the ear to be implanted and 60% or less in the non implanted ear or binaurally.
this aspect of a hearing aid fitting involves impressions being done and sent off to have a custom fitting hearing aid made.
this aspect of the hearing aid fitting involves intruction on cleaning the device, insertion/removal of the aid, insertion/removal of the batteries, etc.
this aspect of the hearing aid fitting involves making sure the aid is actually helping the person out. This process involves real ear measures and functional gain testing.
