NU 606 Exam 2 Questions with verified Answers – Regis College. What is the purpose of speech testing in noise? ️ 1. Assess the patient's concerns using ecologically valid materials/validate patients' reports 2. obtain useful information for counseling (hearing loss/treatment options) 3. validate treatment methods What are the 2 components of test materials for speech in noise testing ️ 1. Targets (what the patient is expected to detect and report) aka speech 2. Maskers (distractions to the patient) aka noise What are some examples of targets for speech in noise testing ️ Monosyllabic words or sentences (entire sentences or key words) What are some examples of maskers for speech in noise testing? ️ Noise (speech shaped, white, pink, brown, etc) Babble (as little as a single speaker up to multi-talker; male, female, or combination) What are the presentation methods for speech in noise testing? ️ Fixed SNR Adaptive SNR Method of constant stimuli What is the fixed SNR presentation method for speech in noise testing? ️ Level of target and noise are constant. Interpreted as % correct. What is the adaptive SNR presentation method for speech in noise testing? ️ either the signal or noise is held constant and the other one changes. Results are presented as SNR loss, which can be difficult to interpret What is the method of constant stimuli for speech in noise testing? ️ SNR decreases by a fixed amount regardless of patient response. Results are presented as SNR loss, which can be difficult to interpret What are some speech in noise tests? ️ R-SPIN, HINT, Q-SIN, WIN, AzBio What is R-SPIN ️ Revised speech perception in noise. Stimuli: low predictability and high predictability sentences with the target word as the last word of the sentence. Presented at 50 dB SL re: threshold of babble and +8dB signal to bable ratio. Scored as % correct What is HINT? ️ Hearing in noise test. Avoids floor and ceiling affects. Test material: PB sentences with male talker. Presented in speech spectrum noise. Adaptive with noise constant at 65dB SPL and speech initially -10dB SNR. Searching for SNR at which patient performs 50% correct. What is Q-SIN? ️ Quick speech in noise. Assess SNR loss. Sentences presented at 6 SNRs. Scoring based on keywords in each sentence. Extrapolate SNR for 50% correct. SNR loss is how much more trouble a listener has than a normal hearing individual What is the modified Q-SIN test battery? ️ includes time compressed + reverberation and N0S(pi) What is WIN? ️ Words in noise test. Direct comparison to speech testing in quiet bc the test uses NU-6 words list. Level of multi-talker babble fixed @ 80dB SPL. Level of speech varried from 104 dB SPL to 80 dB SPL in 4 dB decrements. Scoring: SNR (50%): 26 - # correct * 0.8 What are the best speech in noise tests tests to use? (which tests distinguish performance between normal hearing listeners and listeners with hearing loss according to Wilson et al 2007?) ️ Q-SIN and WIN
