In normal-hearing listeners, FRP increased with narrowing the ripple width. In impaired-hearing listeners, the effect of narrowing the ripple width was minor. The difference between the normal- and impaired-hearing listeners could not be explained by the excitation pattern model of the rippled spectrum resolution. The temporal analysis model did explain this difference on an assumption that in normal hearing listeners, enhancing the autocorrelation of the input signal resulted in prolongation of the delay at which the autocorrelation could be detected by the auditory system, whereas in impaired-hearing listeners this effect was reduced or absent.</p></abstract><trans-abstract xml:lang="ru"><p>Частотную разрешающую способность слуха (ЧРС) оценивали по предельной различаемой плотности гребней спектра у испытуемых в возрасте от 26 до 82 лет, характеризующихся различной степенью сохранности/потери слуха: от нормы (normal) до умеренной потери (moderate loss) по классификации Всемирной организации здравоохранения). Оценивали зависимость ЧРС от ширины спектральных гребней. У испытуемых с нормальным слухом наблюдали повышение ЧРС при сужении гребней сигнала, тогда как у испытуемых с потерей слуха этот эффект проявлялся минимально или отсутствовал. Различие в эффекте сужения спектральных гребней между испытуемыми с нормальным и редуцированным слухом не может быть объяснено моделью спектрального анализа, основанной на концепции профилей возбуждения. Модель временного анализа может объяснить это различие при допущении, что у испытуемых с нормальным слухом увеличение автокорреляции входного сигнала приводит к удлинению задержки, на которой автокорреляция может быть обнаружена, тогда как у испытуемых с редуцированным слухом этот эффект ослаблен или отсутствует.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hearing</kwd><kwd>hearing loss</kwd><kwd>rippled spectra</kwd><kwd>spectral resolution</kwd><kwd>temporal resolution</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слух</kwd><kwd>тугоухость</kwd><kwd>гребенчатые спектры</kwd><kwd>спектральное различение</kwd><kwd>временной анализ</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation, grant 23–25–00148.</funding-statement><funding-statement xml:lang="ru">Работа поддержана РНФ, грант 23–25–00148.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bernstein J.
