102 Multiple choice questions
- a reference point to determine optimal presentation level for suprathreshold word recognition testing
- decrease level by 10 when there is a response; increase level by 5 when there is no response ;
until there are 2 responses in the ascending direction only.
- frequencies (pitches of sound)
- multiple choice
- Word Recognition Score; WRS
- ability to identify speech material at intensity levels above the threshold.
- describe as the best to worst threshold.
- when you have a client who can't perform the SRT.
-clients whose word recognition is so poor that speech is heard but not understood
-young client's who can't respond by pointing to pictures or writing a response
- bone conduction
- + or - 5 dB
- pure tone
- testing that the vocab used is familiar to the client.
determine that client's responses are recognizable to the clinician.
- screening for retrocochlear pathology
- Bone conduction
(b/c vibration of the skull reaches both cochleas)
- three in either ascending or descending directions
- 1000 and 4000 Hz
- SRT should be within + or - 10 dB of the Pure Tone Average
- 1000, 2000, 3000, 4000, 6000, 8000, retest 1000 (first ear only), 500, and 250 Hz
- calibration of the audiometer
- Hearing Handicap Inventory (HHI)
- Instruct the patient
test right ear OR better ear first
begin at 1000 Hz
present each tone for 1 second and vary timing between tones
- increasing performance (% correct) with increasng intensity of speech until plateau
- usually presented via monitored live voice.
Use procedure similar to pure tones.
Ascending procedure may also be used.
- Recorded speech
-greater reliablilty, standardization, comparison btwn listenrs
- familiarization then threshold determination
- Speech Detection Threshold (SDT)
- INTENSITY of sound from -10 to 120 db HL
--LOUDNESS. soft to loud
- FREQUENCIES from 125 to 8000 Hz
--low to high PITCH
- Air conduction threshold
- Speech Detection Threshold
Speech Recognition Threshold
- air conduction
- mode of presentation (MLV v. recorded speech)
- -present words at 50 dB HL (or clearly audible level)
-have client respond to every word
-eliminate problem words
- at least 40 dB SL above the PTA or SRT
- inner ear, auditory nerve and auditory cortex; determined by bone conduction
acoustic reflex thresholds
- is over 20 dB or greater difference between thresholds at adjacent octave intervals (ex: 750, 1500)
- suprathreshold performance
- dB HL
- intervals of pure tones that stimulate specific places in the cochlea
-250, 500, 1000, 2000, 4000, 8000
- suprathreshold performance/Word recognition
- list of monosyllabic words that are phonetically balanced.
Typically open set material
- pure tones
- two-sylable words with equal emphasis on each syllable. common vocab, sound be able to understand and respond to each spondee.
- present the pure tone at 30 dB HL
- increase the level by 10 dB until there is a response
- lowest intensity level at which the listener can detect a sound
- behavioral response
- client may have very poor word recognition ability
- BC abnormal; greater than 15 dB HL
no air bone-gaps; AC and BC thresholds approximately the same at all test frequencies.
- yearly (at least)
- similar to pure-tone threshold method; down 10 up 5.
Need THREE correct responses at the same level; count both descending and ascending responses (b/c recognition required)
(for pure-tone, only need two responses in the ascending direction only)
- Threshold measurement for speech.
suprathreshold speech recognition.
- lower than air conduction
- Identification of the word
pointing to picture or object,
signing or writing the response
- 13 emotional questions and 12 social questions
0 for no
2 for sometimes
4 for yes
- there's an increase in high-frequency thresholds
- sensation level
40 dB ABOVE the speech threshold
- Bone conduction abnormal (>15 dB HL)
Air-Bone Gaps present (>10 dB HL)
- spondaic words; at least 20
- there's an increase in low-frequency thresholds
- Functional Assessment
- 1000, 2000, 4000, 500, 250 Hz
(different from air conduction)
- 1) Is bone conduction abnormal (>15)?
----if yes, sensorineural
2) Are there air-bone gaps present (gaps >10)?
----if yes, conductive
- move on to threshold determination (down 10 up 5)
- usually MLV (monitored live voice)
--b/c of it's flexibility
can be recorded
--standardized speaker, material and presentation level
--recorded speech is inflexible; can't vary the rate of presentation or the test words.
- Oral- repitition of word
can be written or point to pictures
- Hearing Handicap Inventory
- the listener may be exaggerating hearing loss
- not tested
- not important because recognition is not required.
- Bone conduction normal (under 20 dB HL)
Air-bone gaps present (greater than 10 dB HL)
- different pure-tone stimuli transmitted through earphones one ear at a time
can also be conducted in the sound field
- increase the level by 20 dB (to 50 dB HL)
- a technique designed to assess a person's ability to hear and understand speech
- it is in dB SPL, and is set to 0 dB HL
- 40 dB
-will result in optimal word recognition performance
minimum hearing level for speech at which an individual can identify simple speech materials approximately 50% of the time
- should be noed; children's spondees, selected spondees
- outer and middle ear, determined by air conduction
- Speech Recognition Threshold
Suprathreshold speech recognition
- performance decreases with increasing intensity of speech... AKA ROLLOVER**
- bone conduction
- bone conduction thresholds
- you repeat the familiarization and threshold determination processes at different frequencies
- finding a starting intensity level
- Greater SL needed
- two in the ascending direction
- Calculation of the average (mean) loss of hearing for the pure tone thresholds at 500, 1000, and 2000 Hz.
