28
EBP
Evidence-Based Practice
29
EBP involves decision making based on _______ ___________ and critical examination of current and past _______________.
scientific evidence; practices
30
The amount or type of benefit experienced by either an individual or a group of individuals to a treatment or series of treatments, and/or indicates a response
Outcome Measure
31
3 Components of EBP
Current Best Evidence Clinical Expertise Patient Values
32
Comparing participants who have been randomly assigned to receive a test treatment to participants who receive no such treatment
Randomized Controlled Trial
33
5 Step Approach to EBP
1. Ask a Straightforward Question 2. Find Best Evidence to Answer Question 3. Critically Assess the Evidence (does it apply to your patient and is it credible?) 4. Integrate Evidence with Clinical Judgement and Patient Values and Needs 5. Evaluate the performance after having implemented your plan.
34
Speech Recognition/Speech Perception
How well people use auditory and/or visual information to understand spoken messages.
35
Speech Recognition Testing
Assessing how well an individual can recognize speech units (phonemes, words, sentences)
36
T/F | An audiogram alone adequately portrays the communication difficulties an individual with HL may experience
F. Speech recognition measurement is an important element in assessing how hearing loss affects an individual's life and interactions.
37
4 Variables to Consider when Assessing Speech Recognition
1. Purpose 2. Patient Variables 3. Stimuli Units 4. Test Procedures
38
Audiogram
A graphic representation of hearing thresholds as a function of stimulus frequency.
39
Audiometer
An instrument for measuring hearing sensitivity for a range of frequencies. Pure tones are presented.
40
Threshold
The level at which sound can be detected only 50% of the time
41
What does an "A" refer to when seen on an audiogram?
An aided threshold; how the patient hears when wearing a hearing aid. (R and L denote right or left ear amplification.)
42
What does a "C" denote on an audiogram?
A threshold when the patient is wearing a cochlear implant.
43
PTA
Pure Tone Average, | An average of the hearing thresholds for the frequencies of 500, 1000 and 2000 Hz.
44
6 Descriptors Used to Denote Degree of Hearing Loss
``` Normal Mild Moderate Moderate to Severe Severe Profound ```
45
Normal Hearing
The PTA is 25 dB HL or better in adults or 20 dB HL or better in children
46
Mild Hearing Loss
The PTA is between 26 and 40 dB HL
47
Moderate Hearing Loss
The PTA is between 41 and 55 db HL
48
Moderate to Severe Hearing Loss
The PTA is between 56 and 70 dB HL
49
Sever Hearing Loss
The PTA is between 71 and 90 dB HL
50
Profound Hearing Loss
The PTA is poorer than 90 dB HL
51
Flat Configuration
Thresholds are within a 20-dB range of each other across the span of the frequencies tested
52
High-Frequency Configuration
Thresholds are within normal range for the low and mid frequencies, but decline for the higher frequencies.
53
Precipitous and Sloping Configurations
Precipitous is when the HL grows in at least 20 dB increments. Sloping is when the higher frequencies are simply 20 dB or poorer than the low.
54
Low-Frequency Configuration
Thresholds are lowered for the low frequencies bu are within normal range for the mid- and higher frequencies.
55
Saucer-Shaped Configuration
The HL is confined to the mid frequencies.
56
Where does most of the acoustic information that contributes to speech recognition lie?
In the frequency band of 1000 Hz to 3000 Hz.
57
SRT
Speech Recognition Threshold: | The lowest presentation level for spondee words at which 50% can be identified correctly.
58
Spondees
Two-syllable words spoken with equal stress on each syllable.
59
Speech Recognition (Speech Discrimination) Score
The percentage of monosyllabic words presented at a comfortable listening level that can be correctly repeated.
60
MCL
Most Comfortable Loudness level: | The level at which sound is most comfortable for a listener
61
UCL
Uncomfortable Loudness Level: | The level at which sound becomes uncomfortably loud for a listener.
62
Dynamic Range for speech
The difference in dBs between a person's threshold for just being able to detect speech (SRT) and the person's threshold for uncomfortable listening.
63
Testing with a loudspeaker is referred to as what?
Sound Field Testing
64
The means used by a sender to share information with a receiver (speech, sign, writing, etc.) is referred to as
Communication Mode
65
Phoneme stimuli are also referred to as ________
Nonsense syllables
66
What is one advantage of using phoneme stimuli?
Performance is relatively independent of an individual's vocabulary level.
67
What is the disadvantage of using phoneme stimuli?
Poor face validity (phonemes do not require individuals to organize streams of information into meaning the way words do)
68
What is the most commonly used stimuli for assessing speech recognition?
monolyllabic words
69
A PB word list presents what?
A phonetically balanced word list presents a set of words that contain the speech sounds with the same frequency in which they occur in everyday conversations
70
A set of words that are acoustically similar and have approximately the same frequency of occurrence is referred to as
An Acoustic Lexical Neighborhood
71
In which type of lexical neighborhood is it typically more difficult to recognize a word?
Dense Lexical Neighborhood (cat, mat, sat, fat)
72
In which type of lexical neighborhood is it typically easier to recognize words?
Sparse Lexical Neighborhood (thumb, tea, lost)
73
T/F: Word stimuli generally are more difficult to recognize than phrase or simple sentence stimuli.
True.
74
What three features do sentences have that contribute to their high face validity?
Prosodic Cues Contextual Information Coarticulation
75
What is one disadvantage of using sentence stimuli?
Performance can be influenced by linguistic knowledge and familiarity with the topic.
76
What are the three considerations for assessing speech recognition?
1. Test Condition 2. Response Format 3. Live Voice or Recorded Test Materials
77
What might be introduced to increase the difficulty of the listening task or to gain a better understanding of how the person performs int he real world?
Noise | talker babble, white noise
78
SNR
Signal to Noise Ratio: The difference between the sound level of the signal and the sound level of the noise.
79
The difference or ratio between speech recognition performance in a vision-only condition and an audition-plus-vision condition is referred to as
Speechreading Enhancement
80
A stimulus-response set that does not provide choices
Open-set
81
A stimulus-response set that contains a fixed number of items known to the patient
Closed-set
