Modifications to the Power Function for Loudness
This paper reviews recent findings on the form of the loudness function for mid-frequency tones. Loudness matches between pure tones and tone complexes with equal-SL components show that loudness at threshold exceeds zero and that the loudness function approaches a power function with asymptotic exponent (re intensity) somewhat greater than unity at levels well below threshold. They also show t...
متن کاملTemporal integration of loudness, loudness discrimination, and the form of the loudness function.
Temporal integration for loudness of 5-kHz tones was measured as a function of level between 2 and 60 dB SL. Absolute thresholds and levels required to produce equal loudness were measured for 2-, 10-, 50-, and 250-ms tones using adaptive, two-interval, two-alternative forced-choice procedures. The procedure for loudness balances was new and employed ten interleaved tracks to obtain concurrent ...
متن کاملLoudness growth in forward masking: relation to intensity discrimination.
The growth of loudness of a tone burst following an intense forward masker was measured as a function of the tone level. The level of the forward-masked tone was adjusted to balance the loudness of a standard tone presented without a forward masker, using a 2AFC, double-staircase, tracking procedure. The forward masker was a 90-dB SPL, 100-ms, 1000-Hz pure tone. The standard tone and the masked...
متن کاملLoudness and Loudness Discrimination Revisited
We present evidence that the psychophysical function relating loudness to sound pressure is governed by a nonlinear gain control system, one of whose functions is to protect the sensory system from overload. Specifically, the loudness function is altered nonlinearly when loud sounds are added in an identification task previously containing only soft sounds but not vice

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
