Study Notes

Speech Audiometry

  • Speech audiometry is an important part of every audiological assessment
  • Most people seeking audiological help have difficulty hearing speech
  • Measurements of speech help determine reasons for hearing issues

Levels of Speech Perception

  • There exist four levels of speech perception
  • These levels are:
    • Awareness
    • Discrimination
    • Identification
    • Understanding
  • Awareness is the most basic level
  • Awareness involves knowing someone is talking and hearing speech
  • In awareness, the listener cannot make out what is being said
  • Discrimination is the next level
  • Discrimination is the ability to tell two sounds apart
  • Identification is the ability to know what a sound is
  • In Identification, the listener can identify Beetlejuice
  • However in Identification, the listener does not necessarily understand it
  • Understanding is ability to comprehend
  • Understanding is the ultimate goal in audiology
  • Audiology rarely looks at understanding
  • linguistic experience plays a bigger role when going from awareness to understanding
  • Tests performed are mostly at the identification level

Reasons for Performing Speech Audiometry

  • Speech differs for frequencies
  • This determines range
  • Speech is more complex than pure tones and vision
  • You need to pick up differences over both time and frequency
  • Speech assess clarity
  • People with normal hearing thresholds can struggle with speech sounds due to a lack of clarity
  • Causes of lack of clarity include poor temporal processing, poor frequency discrimination, and auditory neuropathy

Speech in Noise

  • People may complain about not understanding others
  • Speech tests can directly reveal these problems
  • Best to measure speech perception with background noise
  • There is a loose correlation between speech in quiet and speech in noise

Differential Diagnosis

  • Speech measures can help in differential diagnosis
  • Can help in determining if issues are conductive or sensory neural
  • Speech results reveal if a patient is trying to fake hearing loss
  • Speech results often reveal hearing loss is not what it seems
  • Speech results are a cross-check for pure tone tests

Speech Reception Threshold (SRT)

  • The speech reception threshold (SRT) is a threshold
  • This is for identifying a speech sound
  • The SRT is measured in decibels hearing level (dB HL)
  • Pure tone average and SRT should match
  • SRT is cross check principle
  • Discrepancies can flag something wrong with the hearing test
  • Audiologists do this before thresholds

Falsified Hearing Tests

  • SRT helps reveal falsified hearing tests
  • This is when people may not be lying due to psychological issues
  • SRT establishes a baseline for other speech tests
  • SRT should be within 10 dB of the pure tone average (500, 1000, 2000 Hz)
  • Discrepancies may indicate faking, equipment issues, or misunderstanding

Abnormal Thresholds

  • If 500 and 1000 Hz are good, but there is precipitous drop to 2000 Hz, speech can still match the average
  • Speech is harder to understand than pure tone
  • Calibration can occur between the two
  • Speech is not one level

Measuring Speech

  • Speech levels constantly fluctuate across frequencies
  • Speech has different short-term levels
  • These are never just one level
  • Speech is measured in 1/8 of a second windows
  • This matches human perception
  • Human auditory system averages sounds
  • The auditory does this with a smoothing window
  • Also in narrow frequency bands, about a third of an octave
  • This approximates a critical band
  • Critical band helps perceive level across frequency

Measuring Short-Term of Speech Levels

  • Measurements are typically done every eighth of second in time
  • Also every third of an octave in frequency
  • Divide like a grid into the perceptual units of auditory system
  • This shows how humans perceives level across frequency and over time
  • Should follow human perception
  • There is distribution of about 30 dB from top to bottom across all frequencies for human speech

Speech Level Considerations

  • Typically measure for at least 10 seconds or more
  • Sentence is measured, short term levels show portion someone can hear of speech sounds
  • Top red line are the peaks in speech spectrum on a graph of speech
  • Bottom red line are the softest ones, 80th percentile
  • Gray line in the middle is the average
  • Referred to the long-term average the speech spectrum (LTAS)
  • Peaks for speech are 12 dB above average level
  • Troughs are 18 dB below

Average Speech Level

  • If the hearing threshold matched the average speech level, you would only hear the top 12 dB
  • You would be missing half of it since it's the softest
  • This is speech is calibrated to around +12 dB on audiometer so it can match
  • So if a speech level measures 0 dB, it is actually like 12.5 dB
  • Calibration balances pure tones with the speech threshold

Calibrating Puretones

  • The test environment calibrates the pure tones and speech
  • This makes it easier for clinicians to assess
  • Measures in HL for speech are different in SPL
  • Set the speech level to around 40 dB HL (soft)
  • This is more like 52.5 dB SPL
  • Calibration values for tones/speech are same, audiometer is raised so people understand
  • It says 10 on the dial speech in dB HL, it's actually higher

Speech Level

  • Speech at 50 dB SPL would be 38.5 dB HL
  • It reads lower on the dial so tones match speech
  • Speech levels in dB HLs are lower than dB SPL
  • Calibration matchs by "lying" the tone levels
  • Using a lower number
  • Goal is to make it easy by matching

Using Spondees

  • Spondees are words with equal emphasis on both syllables
  • These are used with the SRT
  • Examples include Batman, hotdog, and toothbrush
  • Spondees are used because they are easy to hear
  • Familiarize those words with the patient first
    • Ability to hear the vowels is critical

The Importance of Vowels

  • It's important to hear the /t/ and /d/
  • Match tone average because pure tone average is 500, 1000, 2000 Hz where the vowels are
  • Formants are little below 500 with it above 2000 Hz
  • Want to have good pure tone averages due to vowels matching where the formants are
  • Drop the word if a person misses it at a high level to remove clarity/language issues

Thresholds

  • Want easy words to do thresholds with
  • Easy words match average since frequencies match formants with speech
  • Monitor voice recording was common since it helped to present individual words
  • The old day had problems, but a microphone gives flexibility
  • For monitoring, make sure voice/speech hits 0 on VU meter for each syllable to match audiometer's level on dial

Testing Monotone

  • Practice speaking at a monotone to hit 0 with speech level repeatedly
  • Don't use easy words to drop
  • Let face be seen when familiarizing it, but covered when testing unless using audiometer which removes that requirement
  • This helps so machine LEDs don't affect testing
  • It is known that there is a VU meter
  • It is best an audiologist conducts the speech test and has a strong accent

Procedure for Testing

  • The test procedure is very simple
  • It involves familiarizing words to the patient
  • Similar to a hearing test
  • The common procedure is the Martin and Dowdy procedure
  • Test spondees like you would test tones
  • SRT should be within 10 dB of average, or the Fletcher average
  • Fletcher average is best 2/3
  • Fletcher average is preferred if there's a precipitous

Pure Tone Averages

  • People guess vowels if they're only hearing 500 and 1000 Hz
  • Those match just upper frequencies
  • With the Fletcher average, the patient can ignore the one frequency that is way worse
    • It is the best 2 out of 3 of the average
  • If the average goes wrong, then match the Fletcher average
  • Pure averages allow you to know some type of hearing loss
    • Should also be 10 dB within the average
  • This isn't uncommon if using TBH/supraoral closing canals

Pure Tones

  • Pure bone conduction thresholds should match the same with air
  • Collapse that's giving a conductive loss
  • Can depend on orders of tests
  • With misunderstanding, the client would misunderstand air; it helps with fake tests
  • A guideline: air thresholds should get closer
  • Conduct test to see collapsing canal issues and placements of items
  • If there's eustachian tube problems, then the conductive loss helps the hearing

Speech Awareness Threshold

  • Speech awareness/detection threshold is the same thing
  • This involves the cases where the client cannot repeat back the word/is a young kid
  • If they're pre/very linguistic, they might not be able to repeat the words/language
  • Use speech awareness threshold with body language
  • It isn't the same as an SRT, so tend to get +2 to 5 dB better with 5dB steps since no need to repeat
  • You's typically expect a little higher pure tones

Suprathreshold Speech Testing

  • Are like pure tones but will have words in the audiometer
  • Madeline will then show that in the clinic
  • It is reading it off a list with face covered
  • Use the list printed out
  • Other tests are above threshold
  • Not Threshold tests
  • Used to find how clear speech is and if you expect one ear higher thresholds, if right SRT is high, that means SRT is expected better

Expectations for Diagnosis

  • The above SRT should just be 10 within the average
  • List the words to do speech test, then can see in speech audiometry that you should expect if not a neural issue

Scores and Hearing test

  • If speech is audible, you will only get 4% of it
  • A hearing aid isn't needed with 75% of words
  • If pure tones are much worse that means neural issue
  • Speech may be better due to the sounds in quiet not getting a ton of fine details
  • If hearing in speech sounds so low that means bad
  • Speech is not a great way to see damaged parts

Audiology & Testing

  • Know how bad/well certain ears still understand speech
  • Speech in noise/noise alone is a little more sensitive
  • If not hearing anything there is no big need to get more details
  • Speech test underestimate the damaged areas
  • Phonological/language issues can cause problems
  • It depends on speech test type, CVC will interfere and what you should expect after
  • There can also be reasons to local SLPS to see how much worse it can get
  • Is there an expected disorder? So, if nothing there and just hearing loss 75%
  • More moderate loss if making all the levels loud enough when checking 4
  • This is what speech does due to studies

Published Lowest Max Score

  • Judy Debno helped lower max word score relative to pure tones
  • Made a test called PB Max
  • Reason for the name is if the terms stand for phonetically or phonemically balance
  • Multiple max scores you get the best score overall
  • If a test is a done and you get 80 it remains with that same value like 80% since sounds like peanut butter
  • Is the word list and measure clarity for the words the client needs to hear
  • In the end use open set monosyllables

Consonant Vowel Consonant

  • CVC is a words the client needs to recognize with the tester saying, "say the word"
  • It is for more realistic carrier phrases at once constant level
  • Word recognition leads to percent correct on the audiometer since there's buttons to tap
  • Don't monitor the live voice since it is enunciated a lot
  • Testing accent should vary
  • One way to know where the undergrads get it
  • Old audiometers were cumbersome to use
  • Time shouldn't stop administering tests

Dialect Considerations

  • This can also show with recorded accent too but should be done carefully with standardized exact recordings of the test
  • Speech gets there can be an easier use of dialect there
  • Ideal conditions can exist but aren't optimal
  • You shouod ideally have recordings correspondent with different tests in all different clinic
  • Clinician speak test should also be able to score correctly
  • Don't mix southern accent with different language mixes

Tests Tips

  • Do tests at 40dB with pure tone averages if they have high level hearing
  • Can break can then
  • Always defensible with what is upper range most with level
  • Start a few dB and add to see till say level is comfortable
  • The best hearing score would be at their PB Max as well so that the speech not get confused
  • Easy to make mistakes with this in PB because only that will have test right number

Best Speech Score

  • PB Max is 80% and level doesn't affect it since PB is score not the level
  • Can test recognition on profound here and if get less than 5 there's a small chance the aid will help
  • Where test is in cochlear with eligibility with it.
  • Speech will shape fit and frequencies to different levels on the test and what there a level change decision

1st Week Consideration

  • If the person getting above 5% or less than hearing ad will not do it
  • Love picture
  • What more and table score help the test so the amount get higher with repeated use to see percent

Score Considerations

  • Use ten words which might use
  • Should then stop after if think any there's
  • May have do score to fix and use
  • Score should -2 - +2 from other or deviate score for deviations
  • So if get 405 and 110 get for different a is in the list
  • More items should be tested

Range Testing

  • When in the range they say that nothing is really wrong
  • Sprint Charts done in formal test list can change that and know can have more list there
  • Tibodoex 1999
  • List 2 list
  • So 1 is the speech but 1 score is like they had and the one is when did the hearing test again to see
  • Compare 2 change and will use pervious test as other one

List Testing

  • They can do the scores
  • If its and the chart its ok is ok
  • This 2 list you and what level would
  • The chart is if you the 100% means they should get all
  • Below that point means there be some
  • Is for that the they should above one for level with 0
  • Some test and use this with the Ys and look which to for the change is with the chart
