Background: The acceptable noise level (ANL) has been proposed as a prehearing aid fitting measure that could be used for hearing aid selection and counseling purposes. Previous work has demonstrated that a listener's ANL is unrelated to their speech recognition in noise abilities. It is unknown what criteria a listener uses when they select their ANL.

Purpose: The purpose of this study was to evaluate the effect of using slow and fast speaking rates in competing noise on older adults with normal hearing (NH) and those with hearing impairment (HI).

Method: Thirty-four older adults (56-85 years) were grouped based on hearing ability-NH (N = 15) and HI (N = 19). Rate-altered Quick Speech-in-Noise Test (QuickSIN; Etymotic Research, 2001) stimuli were presented at 3 speech rates (slow, average, and fast), and the signal-to-noise ratio (SNR) loss was calculated for each.

Acceptable noise level (ANL) test materials were digitally modified to create five reverberant conditions by applying different values of reverberation time (RT) to a non-reverberant condition (RT = 0, 0.4, 0.7, 1.
