• The characteristics of calls are closely correlated to the ecology of bats , for example , the dominant frequency influences the body size of bats " prey , the detecting range of bats ; the structure of calls decides bats " ability to detect prey in the complicated environment . therefore , the research on factors , which influence the structure and characteristics of ultrasound and on the mechanism by which bats detect and orient the prey will promote the understanding of the ecological behavior of bats
  由于声波的特征和蝙蝠的生态行为有着密切的联系，如声波的主频率影响蝙蝠可探测到的猎物的大小、猎物能被探测到的距离及猎物探测和躲避蝙蝠的能力，声波的结构则影响蝙蝠在干扰环境中探测猎物的能力，因此研究影响蝙蝠声波结构和特征的因素、探讨蝙蝠声波探测和定位的机制，可以更加深入地了解蝙蝠的生态行为。
