Popis:	Loudness balances have been obtained between 10-, 20-, 100- and 1 000-ms tones of different frequencies (62.5, 125, 250, 500, 1 000, 2 000, 4 000, 8 000 and 12 000 Hz), and a constant reference tone of 1 000 Hz and 1 000 ms duration at 40 dB SPL. The absolute thresholds were also measured on the same observers at each duration. Progressive shifts of the equal loudness contours appear when the durations become shorter, in the same direction as the corresponding shifts of the threshold curves; the shifts of the equal loudness contours and the corresponding shifts of the threshold curves do not however appear completely similar; some differences may also exist between tones of differing frequencies. These experiments were preliminary ones; some problems arise, in relation with the technique used; improvements appear necessary
