Gap detection in normal and hearing-impaired listeners

Temporal resolution, estimated by measuring the minimum detectable gap (delta t ms) separating two successive signals, was assessed in five normal-hearing and five cochlear-impaired listeners. The signals were octave-band noises (400-800 Hz, 800-1600 Hz, and 2000-4000 Hz) presented in a background o...

Description
Summary:	Temporal resolution, estimated by measuring the minimum detectable gap (delta t ms) separating two successive signals, was assessed in five normal-hearing and five cochlear-impaired listeners. The signals were octave-band noises (400-800 Hz, 800-1600 Hz, and 2000-4000 Hz) presented in a background of continuous, broadband notched noise that was applied to eliminate unwanted spectral cues. Temporal resolution in all listeners showed systematic improvement with an increase in octave-band center frequency. Resolution in the hearing-impaired subjects was significantly poorer than normal regardless of whether the comparisons were made at equal sound pressure level or at equal sensation level.
