哺乳动物定位声音的能力在物种之间有很大的差异。在过去的十年中，越来越多的证据表明，这种变化不能简单地根据身体线索的可用性来解释。有证据表明，在声音定位的一个主要因素是需要直接的最佳视觉领域的声源作进一步审查。因此，与最佳视野非常窄的物种（如中央凹）相比，最佳视野较宽的物种（如视觉条纹）需要关于声源位置的准确信息。为了支持这一建议，数据报告的最佳视野的宽度的形式视网膜神经节细胞等密度轮廓的13种哺乳动物。其他因素，包括双眼领域，视力，以及在何种程度上是一个物种的掠夺性的生活方式，可能的贡献，也进行了检查。
The ability of mammals to localize sound varies widely among species. During the past decade, evidence has accumulated that this variation cannot be accounted for simply on the basis of the availability of the physical cues for locus. Evidence is presented that a major factor in sound localization is the need to direct the field of best vision to a sound source for further scrutiny. Thus, species with broad fields of best vision (such as visual streaks) require less accurate information regarding the location of a sound source than do species with very narrow fields of best vision (such as foveae). To support this suggestion, data are reported for the width of the field of best vision in the form of retinal ganglion cell isodensity contours for thirteen species of mammals. The possible contribution of other factors including binocular fields, visual acuity, and the degree to which a species is predatory in lifestyle, is also examined.
