Subjects will be seen for four visits to the laboratory. The first visit will involve documentation of informed consent, and measurement of hearing thresholds. The second, third and fourth visits will consist of testing with the following measures (in random order for each subject) to determine if the various implementations of the wind noise reduction algorithm 1) impact speech perception ability, and/or 2) impact sound quality perception. Each session will take approximately 1.5 hours, with a maximum of six hours over all the sessions. The two speech perception tests that will be utilized include : 1) Connected Speech Test and Hearing in Noise Test, 2) The Hearing in Noise Test (HINT) (Nilsson, Soli, & Sullivan, 1994; Koch, Nilsson & Soli, 1995. Overall Impression of Sound Quality and Ratings of Annoyance will be used as subjective, or self-reported, measures of preference. Overall Impression will be influenced by the audibility and masking effect of the noise bursts, whereas Annoyance ratings are significantly correlated to the high frequency emphasis of the stimulus, a potential impact of the extreme suppression conditions (e.g., -18 dB) (Warner & Bentler, 2002; Miedema & Vos, 2003). Both measures will be analyzed as a function of the different time constants, gain reduction levels, and level of presentation.
