Relationship between objective measures of hearing discrimination elicited by non-linguistic stimuli and speech perception in adults

Abstract Some people using hearing aids have difficulty discriminating between sounds even though the sounds are audible. As such, cochlear implants may provide greater benefits for speech perception. One method to identify people with auditory discrimination deficits is to measure discrimination th...

One method to identify people with auditory discrimination deficits is to measure discrimination thresholds using spectral ripple noise (SRN). Previous studies have shown that behavioral discrimination of SRN was associated with speech perception, and behavioral discrimination was also related to cortical responses to acoustic change or ACCs.

In this study, we investigated the relationship between subjective speech perception and objective ACC responses measured using SRNs.

Furthermore, cortical ACC responses to phase changes in the SRN were significantly correlated with speech perception.
