What is aural rehabilitation?
Services and procedures for facilitating receptive and expressive communication in individuals with hearing impairment.
What does aural rehab remediation consist of?
Fitting and monitoring hearing aids or cochlear implants, counseling and referral, intervention to facilitate expressive and receptive communication.
What are the three kinds of decibel measurements used in hearing science?
dB SPL, dB HL, and dB SL
What is 0 dB HL at any frequency?
The mean hearing average threshold for young adults
What is the reference for dB SL?
The individual’s actual threshold.
When is dB SL usually used?
When indicating the level of a stimulus, such as a tone or speech stimulus.
dB HL of stimulus - dB HL of the individual’s threhold =
dB SL
What is 0-15 dB HL?
Normal hearing
What is 16 -40 dB HL?
Mild HL.
What is 41-55 dB HL?
Moderate HL
What is 56-70 dB HL?
Moderately severe HL
What is 71-90 dB HL?
Severe HL
What is 90+ HL?
Profound HL
In which cases is there excellent segmental discrimination with hearing aids?
Mild to Moderate HL
In which cases is there difficult or non-existent segmental discrimination?
Severe to Profound HL
What is segmental discrimination?
The ability to discriminate between different speech sounds
What kind of hearing loss affects the middle or outer ear and the lower frequencies?
Conductive
What type of hearing loss affects the inner ear and decreases hearing sensitivity and frequency and temporal resolution?
Sensorineural
What is frequency resolution?
The ability to hear one tone in the presence of another.
What type of hearing loss involves a tumor of the eighth nerve?
Retrocochlear
What is adventitious hearing loss?
A loss that occurs after language acquisition has already taken place
What ages are pre-lingual?

What is the degree to which a hearing loss affects an individuals ability to function socially, academically or vocationally?
A hearing handicap
What factors affect the degree of handicap?
Age of onset, severity of hearing loss, site of lesion, and family/social support
