本文评估了两种不同版本的Zwicker [Acustica 6,365 - 381(1956)]和Maiwald [Acustica 18,193 - 207(1967)]激励模式模型的强度区分。单波段版本最初是由Zwicker和Maiwald使用的。他们假设，性能是由临界带决定的，在这个临界带中，刺激随着刺激水平的增加而增长得最快。多波段版本基于所有关键波段的信息形成最优决策。将两个版本模型的预测结果与音调的强度区分（作为电平和频率的函数）、部分掩蔽音调和白噪声的数据进行比较。一般来说，单波段版本的预测与脉冲音调的强度分辨率数据在定性上一致，但在定量上不一致。除了高频外，多波段版本的预测结果在定性和定量上都与数据一致。
This paper evaluates two different versions of Zwicker [Acustica 6, 365–381 (1956)] and Maiwald’s [Acustica 18, 193–207 (1967)] excitation‐pattern model for intensity discrimination. The single‐band version is that originally used by Zwicker and Maiwald. They assumed that performance was determined by the critical band in which the excitation grows most rapidly with increasing level of the stimulus. The multiband version forms an optimum decision based on information in all critical bands. Predictions from the two versions of the model are compared to data for intensity discrimination of tones as a function of level and frequency, for partially masked tones and for white noise. In general, the single‐band version yields predictions in qualitative agreement, but not in quantitative agreement with the intensity‐resolution data for pulsed tones. The multiband version yields predictions in good qualitative as well as quantitative agreement with the data, except at high frequencies.
