What does WRS stand for and what is it?
Word Recognition Score and Suprathreshold for hearing and detecting sounds
What is a HHI?
Hearing Handicap Inventory; assesses patients perception of hearing related communication problems
What level do you present the sound to get the maximum WRS? (Flat hearing loss)
40 dB above the SRT or 40 dB SL
What is a Pure Tone Average (PTA)?
The average of pure tone thresholds at 500, 1000, and 2000 Hz in each ear
If SDT is consistent with pure tone testing, what is the acceptable range?
+/- 5 dB of best threshold between 250-4000
What is a rollover?
When word recognition score decreases at higher intensity, sign of retrocohclear pathology
What is a functional assessment?
Type of test that describes the impact of hearing loss on daily function
List the hearing loss configuration types.
In sensorineural loss, the air conduction and the bone conduction thresholds are at the (same/different) frequencies.
What is bone conduction?
Pathway that bypasses outer and middle ear; determines sensorineural sensitivity
What are the 3 categories that are used to describe hearing loss?
Degree (range of thresholds)
Type (conductive, etc.)
What are 3 factors that can influence thresholds?
Proper maintenance and calibration
Pure tones are transmitted via a ____ _______ that is placed on the mastoid process or forehead.
What is the frequency sequence of pure tone testing?
1000, 2000, 3000, 4000, 6000, 8000, retest 1000, 500, and 250
If there is a 20 dB or greater difference between thresholds at adjacent octave intervals in pure tone sequencing, what do you do?
Test the interoctave levels (750, 1500, etc.)
Every times there is no response, increase the intensity level by ___ dB until the person responds again.
Air conduction thresholds reflect the integrity of the total _________ auditory mechanism.
Speech Detection Threshold
minimum hearing level at which an individual can detect the presence of speech material
Speech Recognition Threshold
minimum hearing level for speech at which an individual can identify simple speech materials approximately 50% of the time
Responses Required for SRT
Identification of words
Pointing to picture or object
Signing or written response
Present words at 50 dbHL
Clients respond to every word in the list
Down 10 Up 5 rule
Need 3 correct responses at the same level
Correspond to the pure tone average + or - 10 dB
If SRT is better than PTA then listener may be exaggerating loss
If SRT worse than PTA may reflect poor word recognition ability
Types of hearing loss configuration
Pathway that bypasses outer and middle ear
Sends sounds directly to sensorineural system
Describes the impact
Influences recommendations for intervention
Case History for Children
development of fine and motor skills
social development and educational history
Pertinent identifying information
nature of past and present hearing problems
Prior use of amplification
