34 terms
Terms | Definitions |
|---|---|
 Mixed Hearing Loss | 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. |
| Subjective Test | test measured based on patients response. |
| Objective Test | 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. |
| Play Audiometry | this is a type of subjective test that allows the child to participate in some sort of play task when they hear a sound. |
| Immittance Test | 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. |
| BTE | hearing aid necessary for someone with severe to profound hearing loss. |
| ITE | hearing aid that can be fitted for clients with no greater than sever hearing loss. |
| ITC | hearing aid that can be fitted for clients with mild or moderate hearing loss. |
| CIC | 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. |
| Analog | this type of hearing aid has a physical amplifier; a vibrating diaphragm causes amplification. |
| Digitally Programmable | this type of hearing aid has a physical amplifier and can be programmed by a computer. |
| Fully Digital | this type of hearing aid contains a digital amplifier that is computerized and operate via microchip. |
| Cochlear Implant | 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. |
| Rehabilitation | therapy for a patient who developed speech and language before their hearing loss occurred. |
| Habilitation | 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. |
| Earmold Impression | this aspect of a hearing aid fitting involves impressions being done and sent off to have a custom fitting hearing aid made. |
| Dispenser instructions | this aspect of the hearing aid fitting involves intruction on cleaning the device, insertion/removal of the aid, insertion/removal of the batteries, etc. |
| Verification | 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. |
