Amplification Systems and Aural Rehabilitation Flashcards
Signs of hearing loss in an adult
- Report people mumble
- Trouble hearing with background noise
- Ask for repetition
- Complain about enunciation
- Picked up first by family
- Require you to face them
- Cannot hear people at a distance
- Report people speak quickly
- Tinnitus
- Trouble on the phone but not in person
Signs of hearing loss in a child
- Language delays
- Issues with articulation
- Request repetition
- Requires effort to obtain their attention
- Parent/Teacher notice first
- Issues with academic performance
- Ear pain
The program that screens newborns
Infant Hearing Program
- every baby is screened before they are discharged from the hospital
What age is language progress aided
If aid is provided by 6 months
What are the four effects of hearing loss
- Decreased Audibility
- Decreased Identification
- Decreased Dynamic Range
- Decreased ability to hear in noise
Explain decreased identification
This is when they have trouble distinguishing sounds of different frequencies
Explain decreased dynamic range
The overall range of sounds they can hear are narrower
The soft sounds need to be louder to hear but the loud sounds don’t need to change
They can have a sensitivity to loud sounds
S-N-R
Signal to Noise Ratio
- Signal = sound you want to hear
- Noise = background or distracting noise
What makes someone a candidate?
- Severity of hearing loss
- Speech intelligibility
- Lifestyle
The lower limit considerations consists of …
- Severity of hearing loss
- Speech Comprehension
- Acceptance of noise
- Environment, Needs, Expectations
- Stigma
- Management ability
- Personality
- Central Auditory Processing Disorders
- Tinnitus
- Age
Severity of hearing loss…
More severe the loss the greater the usage
Pure Tone thresholds cant be used to determine the benefit
Speech Comprehension …
Speech reception thresholds have strong evidence to predict benefit
Acceptance of noise…
Using Acceptance Noise Level (ANL) we can determine if they are willing to hear all those extra sounds in the world
ENE
They benefit most in quite environments
Background noise limits low freq hearing
Stigma…
Associated with "being older" Size matters (people willing to pay more for smaller)
Managing instruments…
Low cognitive abilities and dementia etc can cause difficulties with maintaing instrument
Personality
A more open mind perceives there to be more benefits
Central Auditory Processing..
Assistive devices like an FM system can increase benefits
Increases with age
Tinnitus
Can provide relief by amplifying ambient noises giving the brain something else to focus on
Upper limits have ____ hearing loss
Profound
Options for Upper Limit
- Unilateral/Bilateral Cochlear Implants
- Bimodal hearing instrument
- Unilateral/Bilateral hearing instrument
- Bone anchored devices
Medical issues regarding hearing instruments
- Cerumen build up
- Tinnitus
- Vertigo
- Sudden Hearing Loss
- Conductive Hearing Loss
- Unilateral Hearing Loss
Perceived downfalls to hearing instruments
- too noisy
- hard to get into ear
- expensive
- perception of technology
Biggest barriers
- financial expenses
- expensive - minimizing need
- put issues onto others
- denial or go into isolation - stigma
- vanity
- associated with getting older
Overcoming barriers
- family support
- word of mouth referral
- Connectors
- those who dont want to go into isolation
