大型哺乳动物比小型哺乳动物更准确地定位声音的想法经常被注意到，通常被解释为它们的耳间距离很大，并且它们的双耳之间的双耳时间（Δt）和频谱（Δfi）差异也很大。在实验I和II中，在5匹马中确定了单次点击和100毫秒噪声突发的声音定位阈值，并在实验III中测量了1匹马的双耳时间（Δt）和频谱（Δfi）线索的大小。结果表明，虽然Ss有相对较大的耳间距离和物理广泛的双耳定位线索，他们的声音方向阈值显着较差比其他大型哺乳动物-平均22噪声和30点击。看来，声音定位的敏锐度是不是简单地由双耳线索的物理可用性。(29参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The idea that large mammals localize sounds more accurately than small mammals has been noted frequently and is usually explained by reference to their large interaural distance and the correspondingly broad binaural time (Δt) and spectral (Δfi) differences between their 2 ears. In Exps I and II, sound-localization thresholds for single clicks and 100-msec noise bursts were determined in 5 horses, and the magnitude of the binaural time (Δt) and spectral (Δfi) cues for sound direction were measured in Exp III with 1 horse. Results show that although Ss had relatively large interaural distances and physically broad binaural-localization cues available to them, their sound direction thresholds were markedly poorer than those of other large mammals--averaging 22 for noise and 30 for clicks. It appears that sound-localization acuity is not determined simply by the physical availability of binaural cues.(29 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
