The ability to encode information in temporal envelopes of acoustic stimuli is an important skill of the auditory system. It has been demonstrated that a listener's temporal-processing capability is predictive of performance on speech recognition, especially in noisy and complex environments (George, Festen, & Houtgast, 2006; George et al., 2007; Shen, 2014; Snell, Mapes, Hickman, & Frisina, 2002). The goal of this study was to determine whether temporal acuity using gap detection thresholds from the Gap-in Noise (GIN) test (Musiek, 2003) has any relation to the perception of speech in noise from the Revised Speech Perception in Noise (R-SPIN; Bilger, 1984). All younger listeners were between 21 and 30 years (n = 7/mean = 24.7) and older listeners (n = 4/mean = 67.25) were between 65 and 71 years old with audiometric thresholds equal or better than 15 dB HL between 250 and 8000 Hz in both ears, monolingual English, and intact cognitive skills. Results revealed that temporal acuity of older listeners was reduced compared to the younger listeners. Despite temporal processing differences between the two age groups on the GIN test, they performed similarly on the R-SPIN. Results suggest that impaired abilities to process envelope and fine structure cues of acoustic signals does not influence speech perception in background noise.
