Interval scales of sensory magnitude were derived from magnitude and category estimates of loudness differences, loudness similarities, pitch differences, and pitch similarities. In each of the four loudness experiments, a loudness scale was constructed from a nonmetric analysis of the rank order of the judgments. The four loudness scales so constructed were found to be equivalent to one another and indicated that loudness was a power function of sound pressure with an exponent of .29. A similar analysis for the four pitch experiments found the pitch scales derived in each case to be equivalent to one another and linear with the mel scale of pitch. Thus the same sensory and similarities for two distinct perceptual continua. For both pitch and loudness, these sensory scales were used to generate scales of sensory differences. A comparison of the category and magnitude estimates of sensory differences with the scale of sensory differences derived from the nonmetric analyses indicated the presence of significant response biases in both category and magnitude estimation procedures.
感觉量级的区间量表源自响度差异、响度相似性、音高差异和音高相似性的量级估计和类别估计。在四个响度实验的每一个中，通过对判断排序的非度量分析构建了一个响度量表。发现这样构建的四个响度量表彼此等效，并表明响度是声压的幂函数，指数为0.29。对四个音高实验的类似分析发现，每种情况下得出的音高量表彼此等效，并且与音高的美量表呈线性关系。因此，对于两个不同的感知连续体存在相同的感觉和相似性。对于音高和响度，这些感觉量表都用于生成感觉差异量表。将感觉差异的类别估计和量级估计与从非度量分析得出的感觉差异量表进行比较，结果表明在类别和量级估计程序中均存在显著的反应偏差。
