The purpose of this study was to determine the list equivalency of the 18 QuickSIN™
(Quick Speech in Noise test) lists. Individuals with normal hearing (n = 24) and with
sensorineural hearing loss (n = 72) were studied. Mean recognition performances on
the 18 lists by the listeners with normal hearing were 2.8 to 4.3 dB SNR (signal-to-noise
ratio), whereas the range was 10.0 to 14.3 dB SNR for the listeners with hearing loss.
The psychometric functions for each list showed high performance variability across
lists for listeners with hearing loss but not for listeners with normal hearing. For
listeners with hearing loss, Lists 4, 5, 13, and 16 fell outside of the critical difference.
The data from this study suggest nine lists that provide homogenous results for listeners
with and without hearing loss. Finally, there was an 8.7 dB difference in performances
between the two groups indicating a more favorable signal-to-noise ratio required
by the listeners with hearing loss to obtain equal performance.
