用行为学方法获得了两只最小的黄鼠狼(Mustela Nivalis)的听力图。最小黄鼠狼对60dBSPL的听力范围为51~60.5 kHz，最佳听力范围为1~16 kHz。最小的黄鼠狼在听力上似乎与食肉目的其他成员相似，这些成员的数据是可用的。最小黄鼠狼的高频听力能力为功能耳间距离和高频听力之间的关系提供了额外的支持，而在中耳没有明显形态特化的情况下，最小黄鼠狼对低频的敏感性使最小黄鼠狼在小型哺乳动物中不寻常。
Audiograms were obtained for two least weasels ( Mustela nivalis ) using behavioral methods. The hearing range of the least weasel for intensities of 60 dB SPL extends from 51 Hz to 60.5 kHz with a region of best hearing extending from 1 kHz to 16 kHz. The least weasel appears to be similar in its hearing to other members of the order Carnivora for which data are available. The high-frequency hearing ability of the least weasel lends additional support to the relationship between functional interaural distance and high-frequency hearing, whereas its sensitivity to low frequencies in the absence of obvious morphological specialization of the middle ear makes the least weasel unusual among small mammals.
