Abstract
Objectives: Sensitivity to the gliding of ripples in rippled-spectrum signals was measured in both normal-hearing and hearing-impaired listeners.
Methods: The test signal was a 2 oct wide rippled noise centered at 2 kHz, with the ripples gliding downward along the frequency scale. Both the gliding velocity and ripple density were frequency-proportional across the signal band. Ripple density was specified in ripples/oct and velocity was specified in oct/s. The listener's task was to discriminate between the signal with gliding ripples and the non-rippled signal.
Results: In all listener groups, increasing the ripple density decreased the maximal velocity of detectable ripple gliding. The velocity limit of ripple gliding decreased with hearing loss.
Conclusions: The results can be explained by deteriorated temporal resolution in hearing-impaired listeners.
期刊介绍：
The mission of Audiology Research is to publish contemporary, ethical, clinically relevant scientific researches related to the basic science and clinical aspects of the auditory and vestibular system and diseases of the ear that can be used by clinicians, scientists and specialists to improve understanding and treatment of patients with audiological and neurotological disorders.
