The echolocation signals of Rhinolophidae and Hipposideridae are both long CF-FM with 1 harmonic and narrow FM bandwidth. But Rhinolophidae has longer duration, higher duty cycle and lower dominant frequency than Hipposideridae. All the echolocation signals of Vespertilionidae are short FM with 2-6 harmonics and wide FM bandwidth. Vespertilionidae has shorter duration and lower duty cycle than the other two families. There are obvious differences in dominant frequency between different species in this family.

菊头蝠科和蹄蝠科回声定位信号均为长CF-FM型，一般具有1个谐波，调频带很窄，但菊头蝠科的持续时间和能率环明显高于蹄蝠科，蹄蝠科能量最大处频率高于菊头蝠科；蝙蝠科回声定位信号均为短FM型，具有2～6个谐波，持续时间和能率环比其他两科低，调频带很宽，能量最大处频率在种间变化较大。

The sibship of the three families was concluded from echolocation signals. There is very close sibship between Rhinolophidae and Hipposideridae, which possibly evolved from the same original group. Vespertilionidae is an isolated group with little affinity to Rhinolophidae and Hipposideridae, probably evolving from another original group.

回声定位信号特征推断出三科蝙蝠之间的亲缘关系：菊头蝠科与蹄蝠科有很密切的亲缘关系，很可能由同一原始种群进化而来；蝙蝠科是一独立的种群，与菊头蝠和蹄蝠的亲缘关系较远，可能由另一原始种群进化而来。

There is obvious negative correlation between dominant frequency and bodily size in Rhinolophidae, Vespertilionidae and Hipposideridae.

菊头蝠科、蝙蝠科和蹄蝠科回声定位信号能量最大处频率与体型呈明显的负相关，蝙蝠科相关性最好，其次为蹄蝠科，较差的为菊头蝠科；能量最大处频率与前臂长的回归线表明：对于前臂长相同的蝙蝠，蹄蝠科的能量最大处频率远远高于其它两科，菊头蝠科高于蝙蝠科。
