Title
Subjective Assessment of Hearing Performance: The Hearing in Noise Test,Used
Delivery time: 8-12 business days (International)
The purpose of this study was to evaluate the 12 standard test lists of the Quick SpeechinNoise test (QuickSIN) for equivalency of across list and signaltonoise ratio (SNR) and for testretest reliability for binaural soundfield listening. The results of the QuickSIN were compared with word recognition scores for Northwestern University No. 6 (NU6) word Lists 1A and 2A presented in the QuickSIN babble. Further, the relation between the QuickSIN results and the Abbreviated Profile of Hearing Aid Benefit (APHAB) scores were evaluated. Two groups of adults (N = 36 per group), with normal hearing sensitivity (NH) and with mild to moderate sensorineural hearing impairment (HI), participated in a test and retest session separated by one to two weeks. Each participant completed the APHAB, received the 12 QuickSIN standard test lists in counterbalanced order, and the NU6 List 1A (test) and 2A (retest) in the QuickSIN babble at a SNR based on the participant?s mean QuickSIN SNR50 score for the session.
