Amplitude modulation reduces loudness adaptation to high-frequency tones.
Long-term loudness perception of a sound has been presumed to depend on the spatial distribution of activated auditory nerve fibers as well as their temporal firing pattern. The relative contributions of those two factors were investigated by measuring loudness adaptation to sinusoidally amplitude-modulated 12-kHz tones. The tones had a total duration of 180 s and were either unmodulated or 100...
متن کاملLoudness of low-frequency pure tones lateralized by interaural time differences.
Directional loudness is that phenomenon by which the loudness of a sound may vary according to the localization of its source. This phenomenon has been mainly observed for high-frequency sounds, for sources located in the horizontal plane. Because of the acoustic shadow of the head, the left and right ear pressures are modified depending on the source azimuth and the global loudness resulting f...
متن کاملPitch , loudness and frequency selectivity in low - frequency hearing loss
Patients with Ménière's disease and cochlear hydrops show fluctuating low-frequencyhearing loss (FLFHL). At present these changes are followed as patients' subjectivereports and occasional measurements. Consecutive long-term measurements shouldprovide more comprehensive information on the hearing fluctuations than theoccasional audiogram used today and constitute an approach...

مطالعه حاضر با هدف بررسی وجود رابطه ی ممکن میان هوشهای زبانی و منطقی زبان آموزان انگلیسی و تعداد و انواع مغلطه های زبانی و شواهد در متنهای استدلالی آنان انجام پذیرفته است.بدین منظور، 70 زبان آموز با سطح زبانی متوسط به بالا از دو موسسه زبان انگلیسی در ایران انتخاب شده و پرسشنامه های مزبوطه را تکمیل نموده و متنی استدلالی نوشتند. متون نوشته شده مورد بررسی قرار گرفته و نمرات پرسشنامه ها محاسبه شده ...
15 صفحه اولEqual-loudness-level contours for pure tones.
Equal-loudness-level contours provide the foundation for theoretical and practical analyses of intensity-frequency characteristics of auditory systems. Since 1956 equal-loudness-level contours based on the free-field measurements of Robinson and Dadson [Br. J. Appl. Phys. 7, 166-181 (1956)] have been widely accepted. However, in 1987 some questions about the general applicability of these conto...
