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.
通过测量分隔两个连续信号的最小可检测间隙（δt毫秒）来估计时间分辨率，对五名听力正常的听众和五名耳蜗受损的听众进行了评估。信号为倍频程带噪声（400 - 800赫兹、800 - 1600赫兹和2000 - 4000赫兹），呈现于连续宽带陷波噪声背景中，该背景噪声用于消除不需要的频谱线索。所有听众的时间分辨率均随倍频程带中心频率的增加而呈现系统性改善。无论在等声压级还是等感觉级下进行比较，听力受损受试者的分辨率均显著低于正常水平。
