Subjects judged the loudness of tones (Experiment 1) and of bursts of noise (Experiment 2) that varied in intensity and duration as well as in mode of presentation (monaural vs. binaural). Both monaural and binaural loudness, for both types of signals, obeyed the bilinear-interaction prediction of the classic temporal integration model. The loudness of short tones grows as a power function of both intensity and duration with different exponents for the two factors (.2 and .3, respectively). The loudness of wide-band noises grows as a power function of duration (with an exponent of approximately .6) but not of sound pressure. For tones, binaural summation was constant but fell short of full additivity. For noises, summation changed across level and duration. Temporal summation followed the same course for monaural and binaural tonal stimuli but not for noise stimuli. Notwithstanding these differences between tone and noise, we concluded that binaural and temporal summation are independently operating integrative networks within the auditory system. The usefulness of establishing the underlying metric structure for temporal summation is emphasized.
受试者判断了不同强度、时长以及呈现方式（单耳与双耳）的纯音（实验1）和噪声脉冲（实验2）的响度。对于这两种类型的信号，单耳和双耳响度均符合经典时间整合模型的双线性交互预测。短纯音的响度随着强度和时长的幂函数增长，两个因素的指数不同（分别为0.2和0.3）。宽带噪声的响度随着时长的幂函数增长（指数约为0.6），但不随声压增长。对于纯音，双耳总和是恒定的，但未达到完全可加性。对于噪声，总和随声级和时长而变化。单耳和双耳纯音刺激的时间总和遵循相同的过程，但噪声刺激则不然。尽管纯音和噪声之间存在这些差异，但我们得出结论，双耳总和与时间总和是听觉系统中独立运作的整合网络。强调了建立时间总和潜在度量结构的有用性。
