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.
许多物种的啮齿动物在交配、攻击及其他活动中会发出短暂的超声波叫声。蒂森和基特雷尔（1979年）推测，沙鼠发出超声波是某些运动行为中胸部受到物理挤压产生的声学副产品。我通过将沙鼠超声波与运动过程中的呼吸生物力学联系起来，进一步拓展了这一假设。我还提出，其他啮齿动物物种的至少一些超声波发射，与沙鼠的一样，是运动过程中胸部受压的副产品。这一观点的依据来自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，这种关于啮齿动物超声波的不同观点对超声波研究中实验结果的解释以及对啮齿动物交流中信息和意义的理解都有影响。
