许多种类的啮齿动物在交配、攻击和其他活动中会发出短促的超声波发声。Thiessen和Kittrell(1979)假设，沙土鼠发出的超声波是在某些运动行为中对胸部进行物理压缩的声学副产品。通过将沙鼠超声波与运动过程中呼吸的生物力学联系起来，我进一步支持了这一假设。我还认为，其他啮齿动物的超声波辐射至少有一部分是像沙鼠一样，是运动过程中胸部受压的副产品。对这一建议的支持来自于文献中对超声波发射的描述以及对大鼠交配行为的慢动作分析。最后，这种对啮齿动物超声波的另一种看法对于解释超声研究中的实验结果以及理解啮齿动物交流中的信息和意义都有影响。
Rodents of many species emit short ultrasonic vocalizations during copulation, aggression, and other activities. Thiessen and Kittrell (1979) hypothesized that ultrasound emission by gerbils is the acoustic by-product of physical compression of the thorax during certain locomotor behaviors. I carry this hypothesis further by relating gerbil ultrasound to the biomechanics of respiration during locomotion. I also suggest that at least some of the ultrasonic emissions of other rodent species are, like the gerbil's, by-products of thoracic compression during locomotion. Support for this suggestion comes from descriptions in the literature of ultrasound emission as well as slow-motion analysis of rat copulatory behavior. Finally, this alternative view of rodent ultrasound has consequences for the interpretation of experimental findings in ultrasound research and for the understanding of messages and meanings in rodent communication.
