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.
已获得不同频率（62.5、125、250、500、1000、2000、4000、8000和12000赫兹）的10毫秒、20毫秒、100毫秒和1000毫秒音调与40分贝声压级下1000赫兹、1000毫秒持续时间的恒定参考音调之间的响度平衡。还在相同观察者身上测量了每个持续时间的绝对阈值。当持续时间变短时，等响度曲线会出现渐进性偏移，偏移方向与阈值曲线的相应偏移方向相同；然而，等响度曲线的偏移和阈值曲线的相应偏移并非完全相似；不同频率的音调之间也可能存在一些差异。这些实验是初步的；与所使用的技术相关出现了一些问题；似乎有必要进行改进。
