List 3 reasons why we test SRT Answer ✔✔•Validates results found for pure tones •Helps determine appropriate gain when fitting hearing aids •Helps determine appropriate db level of supra-threshold speech testing SRT should be within __ db of any one of the pure tone averages Answer ✔✔+/- 10 According to Stach, SRT will agree with the (best/worst) pure tone threshold on the audiogram Answer ✔✔best What does poor SRT and pure tone agreement entail? Answer ✔✔Pure tone thresholds may not be valid SRTs may not be valid What is a spondee word? Why are they used in SRT? and examples Answer ✔✔: 2-syllable word in which each syllable is a word (compound word) *a stimulus for SRT testing*

Answer ✔✔Pure tone thresholds may not be valid SRTs may not be valid What is a spondee word? Why are they used in SRT? and examples Answer ✔✔: 2-syllable word in which each syllable is a word (compound word) a stimulus for SRT testing •Homogenous with respect to audibility—equal stress on each syllable •Highly redundant and predictable •Easy to discriminate •Easy to id even in only part of the word is heard; so, could use all 50 from the list or just 10 Ex: airplane, birthday, mushroom, cowboy, outside, oatmeal When familiarizing pt with spondee words, remember: Answer ✔✔reason intensity level technique - if pts cannot understand a word lip reading
only use words the pt knows What is the reason for familiarization of spondee words? Answer ✔✔want to see how soft a pt can hear speech and if they can repeat it back What is the intensity level for familiarization of spondee words? Answer ✔✔- begin at most comfortable listening level Why is there lip reading for familiarization of spondee words? Answer ✔✔pt can do this when familiarizing in live voice Range of normal limits for SRT Answer ✔✔20db or better - adults 15db or better - child SRT Degrees of HL Answer ✔✔(same as pure tone) Slight HL: 16-25db Mild HL: 26-40db Moderate HL: 41-55db Mod. Severe HL: 56-70db Sever HL: 71-90db Profound HL: 90+ db Name 3 Audiometric Inputs for SRT Testing Answer ✔✔microphone tape recorded test cd recorded test What is the test format for an SRT? Answer ✔✔Audiologist may give a lead in phrase that is the same for each word given EX: "say the word __", "say ___", "you will say ___"
Different names for Word Recognition testing: Answer ✔✔Speech Discrimination Word Discrimination PB Word Testing What is Word Recognition Testing? Answer ✔✔: a hearing test that measures how well you can hear words isolated from the context of a sentience in an ideal situation - the perfect volume, no external noise, no distractions, etc. Purpose of WRT? Answer ✔✔: to determine pts ability to understand words in isolation presented at an amplified hearing level Procedure for WRT Answer ✔✔Present the listener with a list of words or sentences Typically via earphones but some applications for sound field presentation Presentation level is constant for the entire list Score as percent correct (90% correct) •Whole word •Phonemes correct What do the results fo WRT tell us? Answer ✔✔-Gives extent of pts word rec ability
•Mod. Difficulty: 60-75% •Poor Discrimination/marked difficulty following convo: 50-60% •Very poor: <50% What stimulus is used for WRT? Answer ✔✔A list of monosyllabic words used for determining word rec scores Each list contains the same distribution of phonemes that occur in connected SAE Goal of Word Recognition Testing Answer ✔✔: To determine maximum word rec ability regardless of intensity level For those w HL it is advised that a fixed presentation level be considered—this also has limitations (ex: if someone has a SN hl they may need it louder/softer to get their best score) Research shows best scores bw __-__db SL(sensation level: how much it is above their threshold) for individuals w normal hearing Answer ✔✔ 20 - 40 For those w HL it is advised that a ____ presentation level be considered—this also has limitations (ex: if someone has a SN hl they may need it louder/softer to get their best score) Answer ✔✔fixed Why can scores vary dramatically w identical pure tone audiograms for people with SN HL? Answer ✔✔word rec is a much more complex task than is reflected in the pure tone audiogram Generally, the (less/more) severe the SNHL, (worse/greater) effect on the word rec score Answer ✔✔more greater If intensity of stimulus overcomes conductive component, word rec scores are typically ___. Answer ✔✔excellent Procedure for WRT: Answer ✔✔Administer 40db ABOVE SRT
