我们进行了三个实验，以确定在声级没有物理变化的情况下，与测试声音的感知距离的变化是否会影响其响度。视觉捕捉现象为操纵视距离提供了手段。一个“虚拟”扬声器被用来改变短噪音刺激的表面来源位置，而这个声音的真正来源相对于观察者保持固定（和隐藏）。在消声或半混响声学环境中，将40至75分贝(A)的声级呈现给独立的观察者组。一般来说，报告的响度随着感知距离的增加而增加。这一发现暗示了响度恒定现象的概念化。
Three experiments were conducted to determine whether variations in the perceived distance to a test sound could influence its loudness in the absence of physical changes in sound-level. The phenomenon of visual capture provided the means for manipulating apparent distance. A ‘dummy’ loudspeaker was used to vary the apparent source location of a short noise stimulus while the true source of this sound remained fixed (and hidden) with respect to the observer. Sound-levels from 40 to 75 dB(A) were presented to independent groups of observers in either anechoic or semi-reverberant acoustical environments. In general, reported loudness increased with perceived distance. This finding has implications for conceptualizing the phenomenon of loudness constancy.
