Loudness as a Function of Duration

Temporal 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 ...

Two-flash thresholds as a function of comparison stimulus duration.

Gamma-ray Burst Peak Duration as a Function of Energy

Gamma-ray burst time histories often consist of many peaks. These peaks tend to be narrower at higher energy. If gamma-ray bursts are cos-mological, the energy dependence of gamma-ray burst time scales must be understood in order to correct the time scale dependence due to the expansion of the universe. By using the average autocorrelation function and the average pulse width, we show that the ...

Single - letter recognition as a function of exposure duration

The time course of visual letter recognition was investigated in a single-stimulus identi®cation experiment. On each trial, a randomly chosen stimulus letter was presented at 1 of 12 equiprobable positions that were equally spaced around the circumference of an imaginary circle centered on ®xation. Exposure duration was varied from 10 to 200 ms, and the letter was followed by a pattern mask. Th...

Modelling pause duration as a function of contextual length

Effects of contextual length are known to affect pause durations in neutral speech. The present study investigates these effects on an expressive corpus of read tales in French. Computational models of intra-sentence, and inter-sentence pause durations, as functions of contextual lengths are proposed. These models are aimed at improving Text-To-Speech synthesis systems, and provide clues for sy...
