在一个频率上听相对强烈的音调，在另一个频率上听较弱的音调，会使后者相对更大声。听觉系统对低频（f1）和高频（f2）音调的相对反应取决于f1和f2之间的分离。当f1和f2相差不大时，响度匹配随各频率平均声压级（SPLs）变化不大；但当f1和f2的差异更大时，匹配就会发生显著变化，这表明听觉系统如何“重新校准”它对f1和f2的反应。再校准的幅度及其频率带宽也在一定程度上取决于SPLs的范围、它们的平均水平和实验范式。响度的表征反映了在更高层次的上下文敏感（类似适应）机制中对多维外围输入的处理和重新校准。其他知觉模式也显示出类似机制的证据。
Listening to relatively intense tones at 1 frequency and weak tones at another makes the latter relatively louder. The auditory system’s relative response to low-frequency (f 1) and high-frequency (f 2) tones depends on the separation between f 1 and f 2. When f 1 and f 2 differ little, loudness matches change little with shifts in mean sound pressure levels (SPLs) at each frequency; but when f 1 and f 2 differ more, matches change markedly, showing how the auditory system “recalibrates” its responses to f 1 and f 2. The magnitude of recalibration and its frequency bandwidth also depend to a modest degree on the range of SPLs, their mean level, and the experimental paradigm. The representation of loudness reflects the processing and recalibration of multidimensional peripheral inputs within a higher level, context-sensitive (adaptationlike) mechanism. Other perceptual modalities show evidence of analogous mechanisms.
