2 general principles of amplification
Amplification is the primary tool ; amplification is always incomplete and imperfect4 Purposes of amplification
4 Purposes of amplification
to amplify speech to audible yet comforavle levels; help in sound localization; help in sound detection; in a child helps to develop spocken language
3 types of amplification systems
personal hearing aids;assitive listening devices; cochlear implants
5 basic parts and concepts of a hearing aid
microphone;amplifier; loudspeaker;power source; controls
4 new technology has changed
digital processor; miniaturization; audiologist involved in distribibution; most are custome built
3 general posstive changes in amplicication
customization has lead to greater awareness of individual differences; assesment procedures are more sophisticated; quality care better
5 challenges that we face
envirometal problems background noise; no one correct path; competition; cosmetics;no universal goals
2 more challenges that we face
no corelatuion of benifit to anything; underutilization
4 probems with assesment
no correlation; communication difficultuies vary as a function of mnay variables;no single measure covers all aspects; measures are not individual-specific
what 5 domains are assessed
perception of speech communication difficulties;perception of reactions and behaviors of othes;perception of self emotional reactions;nonspeech problesm;related problems
applications of cosi 5
screener;case history; plan rehabilitation; mesure benifit; to someday determine compensation
4 ideal outcomes of use of self report
workable list of that person's problems;categorizationof person or at least HA canidacy; obtain baseline data; tje process itself may reduce denial

what are the two types of hearing aids
the first type has two parts the coupler and the hearing aid, the second has one part the coupler is built into the hearing aid

body aid, behind the ear (bte) and the eye glasses
what are some examplies of the one part hearing aid
Define detection
being aware of sound
define discrimination
the ability to distinguish among the individual speech stimuli
define identification
the abilty to identify and or label what is heard
define attention
the ability for someone to focus or attend what the spoeacker is trying to convey
define memory
the ability to retain or store verval information
Define closure
the percievced elements must be brought together in a meaningful whole
define comprehension
full perception and understanding of the auditory message
what are the three most commonly encounterd auditory situations
relatively intense background noise;the presence of a competing speech signal; and listening on the telephone
what is speech reading
visual perseption of communication
what are the 4 general areas that fall into the speech reading process
the speaker. the signla code, the enviroment , and the speechreader
what is a viseme
this is a group of phonemes in which each look alike whe spoken
what are the four groups that you can classify consonant into
bilabials, rounded labials, labiodentals. nonlabials
List the five steps in the selection and fitting of a hearing aid hearing aid
1. select the candidate 2. pre-selection measurement 3. hearing aid selection 4. verification. 5. post fitting counseling
describe in the hearing aid candidacy several factors that imly
medical, audiologic, and personal
what are some factors that relate to the "potential for benifit" to a person who is thinking of getting a hearing aid
benefit relatied DIRECLY to problems / no standerdized definition or measure/ typical correlates ( amount of use) (retained after trial)
what is the minimum criteria needed for hearing aid canidacy
measurable heairng loss . absence of medical contrications/ potential benifit /can aquare the aid
name the ideal canidate
working type person / tangible problems/ mild to moderate hearing loss (30-65 hl) / good speech discrimination/ motivated
describe a bad candidate for a hearing aid
heairng loss has difficult configureations/ poor sppech discrimination/ vague problem areas/ poor attitude/ unteachable / no reason for getting one
what is step 2 of the hearing aid assesment prosess and what are they
pre-selection measurements / speech understanding/ loudness jugemtns
what is step three of the hearing aid assesment prossess
the four questions
style technology options and how many
what is step four of the hearing aid assesment
verification of performance / quality control/ physical fit/ preformance
what is step five of the hearing aid assesment
post fitting follow up/ cousling / hearing aid use and adjustment/ instructions
what are the key components of the hearing aid
battery/ microphone/ amplifier/ reciever/ volume control
why are so many people "unaplified"
1. Perception that their was minimal;
2. Consumer issues (cost, priority)
3. Professional’s opinion (negative, recommend)
4. Perceived product value
5. Perceived product features
list problems associated with hearing aid use and the solutions
instrument has no sound/ or is weak
instrument whistles/ sound is distorted/ buzzing sound/ swelling
cause of instrument has no sound
battery polarity reversed/ low or dead battery/ clogged wax guard/ volume turned down
causes of instrument whistles
improper seating in ear/volume control too high/excessive wax in ears
causes of instrument Sound is distorted or intermittent
low battery battery compartment is not completely closed , hearing aid could not be fitted properly
causes of instrument swelling or discharge in ear
solution: check with your physician
describe "signal to noise ratio" what contributes to it and why is this importortant
is a measure of signal strength relative to background noise. The ratio is usually measured in decibels (dB).
if the background noise is to loud you won't be able to hear the person speaking and vise vera
Why do hearing aids have poor signal to noise ratio
because the microphone in a hearing aid is not able to know what sound you want to listen to more closely
How can poor signal to noise ratio be improved
Directional Microphones and FM systems/Directional Microphones and FM systems/
what are some alternative amplification systems
cochlear implant/ assistive listening device/ personal hearing aids/group and personal amplification devices
what are some advantages and limitations of the infrared system
advantages: wireless transmission/high-quality signal/ uses various types of receivers/ can be used simultaneously in-adjacent rooms/ Limitations: limited portability/ erson confined to a certain area for listening/ receiver must be in direct line with transmitter for maximum sound quality/ cannot be used outside because i is subject, which degrades sound quality/
what are some advantages and disadvantages of a fm system
advantages: wireless transmission/ high quality signal/most flexible system/ use various types of receivers/ indoor and outdoor use possible/ Electroagnetic interference not a problem/ radio interference possible
what are some advantages and disadvantages of a cochlear implant
permanent/ degrades any chances of having your own hearing. a major surgery/ and major rehabilitation needed
What are three anticipatory strategies for a person with hearing loss
minimizing the distance between from the speaker/ optimizing the hearing aid volume setting/ reduce competing signals/ use situational cues
what are some repair strategies for people with hearing loss
ask speaker to repeat part or all of message/ ask speaker to rephrase or simplify the message/ ask about follow up messages
