A fundamental property of hearing is that signals become more detectable as their bandwidth is increased. Two models have been proposed to account for this result. The integration model assumes that detection is mediated by the output of a single frequency channel matched in bandwidth to the signal. The multiple-looks model assumes that detection is based on the combination of outputs from multiple channels matched to the individual frequencies of the signal. Results are reported supporting the integration model.
听力的一个基本属性是，随着带宽的增加，信号变得更容易被察觉。有两种模型被提出来解释这一结果。整合模型假设检测是由与信号带宽匹配的单个频率通道的输出介导的。多视图模型假设检测是基于与信号各个频率匹配的多个通道的输出组合。报告的结果支持整合模型。
