[Relationship between evaluation of the duration and loudness of short sounds].
The relation between loudness and duration judgments of short tones was investigated. Sounds (15 to 120 ms, 2500 Hz, about dB SPL), were exposed in pairs; one tone of the pair, the first or the second one, was twice as long as the other. Subjects had to compare the loudness of the tones, or the duration, or the loudness and the duration at the same time. Results show that the loudness judgments are independent of experiences with duration judgments and of immediate duration judgments, but duration judgments were less precise when loudness judged at the same time.
