slhs test 2 4801 All Questions Correctly Answered speech audiometry - ANSWER- measurement of hearing using speech primary uses of speech audiometry - ANSWER- 1) describe ability to understand speech 2) measure the distortion component of hearing loss 3) useful for fitting hearing aids and counseling dB SPL - ANSWER- Sound pressure level dB SPL reference - ANSWER- 20 micropascals sound pressure level - ANSWER- a physical measure of sound dB HL - ANSWER- hearing level dB HL reference - ANSWER- average group of normal hearing threshold we use this for pure tones on an audiogram - ANSWER- dB HL suprathreshold - ANSWER- a level that is above threshold dB SL - ANSWER- sensation level sensation level - ANSWER- a measure of level referenced to an individual persons threshold if your threshold is 40 dB HL then what level are you presenting in dB HL is you want to present a stimulus at 35 dB SL? - ANSWER- 75 dB HL why do we do speech audiometry - ANSWER- 1) speech is the stimulus we use for communication 2) helps us confirm the accuracy of pure tone audiogram 3)gives us an estimate of speech recognition and comprehension 4) test comfort levels of speech some tests measure the (blank) of speech - ANSWER- detection (is the signal present or absent) some tests measure the (blank) of speech - ANSWER- threshold for the recognition (at what level can a patient just recognize a word) if we present words to a person and ask them to raise their hand when they hear it, is this a measure of detection or recognition? - ANSWER- detection effects of sensorineural hearing loss - ANSWER- audibility and distortion audibility - ANSWER- lower level sounds cannot be heard distortion - ANSWER- suprathreshold sounds are distorted; the auditory system is missing some neural equipment to encode and process sound; frequency resolution is poorer and dynamic range is smaller and loudness growth is abnormal how do we measure distortion - ANSWER- we want to know how the SNHL is interfering with speech perception when speech is above threshold SAT - ANSWER- speech awareness threshold speech detection threshold - ANSWER- SDT SRT - ANSWER- speech recognition threshold WRS - ANSWER- word recognition score all of these speech measures are measured in dB HL - ANSWER- SAT, SDT, SRT, MCL, UCL, LDL all of these speech measures are measured in % correct or dB SNR - ANSWER- WRS, sentence recognition, recognition of speech in noise most comfortable loudness - ANSWER- MCL uncomfortable loudness - ANSWER- UCL loudness discomfort level - ANSWER- LDL speech can come from - ANSWER- recording or MLV benefits of recording - ANSWER- doesnt change from day to day, less variable so more control monitored live voice - ANSWER- tester speaks the words into the microphone and uses the audiometer to adjust the level, more variability but can go faster true or false: monitored live voice is a more consistent way of presenting speech stimuli to patient - ANSWER- false how do we deliver the speech stimuli - ANSWER- through transducers
