最近关于响度的研究主要集中在响度的上下文影响上，包括同化和重新校准。当前的实验检查了响度重新校准 [Marks, J. Exp.心理。 20, 382-396 (1994)]。在第一个实验中，使用自适应跟踪程序来测量响度重新校准作为标准和重新校准音调级别的函数。标准音调频率为 500 和 2500 Hz，电平为 80、70、60 和 40 dB SPL 以及阈值。在 60 dB SPL 条件下获得了 17 dB 的响度重新校准（两个频率的组合）。这一响度重新校准量虽然很大，但仍然小于 Marks 使用配对比较方法获得的值 (22 dB)。第二个实验试图重复马克斯早期的实验 [Marks, J. Exp.心理。 20, 382-396 (1994), 实验 2]。该实验的结果（21 dB）与 Marks 获得的结果几乎相同。实验1的结果表明，当重新校准音比随后的标准音适度大时，响度重新校准最大。当标准音调水平等于重新校准音调水平时，表现出相对小的响度重新校准。此外，阈值处没有响度重新校准。跟踪程序还发现响度重新校准的开始速度非常快。在每个频率处获得的最大响度重新校准之间的差异（500 Hz 时为 11 dB，2500 Hz 时为 6 dB）表明响度重新校准取决于标准音调的频率。 (C) 1999 年美国声学学会。 [S0001-4966(99)01312-0]。
Recent research on loudness has focused on contextual effects on loudness, both assimilation and recalibration. The current experiments examined loudness recalibration [Marks, J. Exp. Psychol. 20, 382-396 (1994)]. In the first experiment, an adaptive tracking procedure was used to measure loudness recalibration as a function of standard- and recalibration-tone level. The standard-tone frequencies were 500 and 2500 Hz and the levels were 80-, 70-, 60-, and 40-dB SPL, and threshold. Seventeen dB of loudness recalibration was obtained (combined over both frequencies) in the 60-dB SPL condition. This amount of loudness recalibration, while substantial, is still less than that obtained by Marks (22 dB), using the method of paired comparisons. The second experiment sought to duplicate Marks' earlier experiment [Marks, J. Exp. Psychol. 20, 382-396 (1994), experiment 2]. The results of this experiment (21 dB) were almost identical to those obtained by Marks. The results of experiment 1 indicate that loudness recalibration is maximum when the recalibration tone is moderately louder than the subsequent standard tones. Relatively little loudness recalibration is exhibited when the standard-tone level equals the recalibration-tone level. In addition, there is no loudness recalibration at threshold. The tracking procedure also identified that the onset of loudness recalibration is very rapid. The difference between the maximum loudness recalibration obtained at each frequency (11 dB at 500 Hz, 6 dB at 2500 Hz) suggests that loudness recalibration is dependent upon the frequency of the standard tone.
