Speech Perception Ability in Noise is Correlated with Auditory Brainstem Response Wave I Amplitude.

BACKGROUND Difficulty understanding speech in background noise is a common complaint of individuals with sensorineural hearing loss. Recent animal studies suggest this difficulty may be due, in part, to spiral ganglion cell degeneration related to aging or noise exposure. Although auditory brainstem response (ABR) thresholds and standard clinical… (More)
