蝙蝠在不同环境中的夜间活动可以使用外差装置来测量，该装置将超声波回声定位的叫声转换为可听到的“滴答声”。通过这种方法获得的初步结果表明，蝙蝠在湖泊上空比在溪流或田野上更活跃，在有建筑物的农村地区比在没有建筑物的无人居住的林区更活跃。研究发现，雨会抑制蝙蝠的夜间活动。
Nocturnal activity of bats over different environments may be measured using a heterodyning device which converts the ultrasonic echolocating cries to audible "clicks." Preliminary results obtained by this method indicate that bats are more active over lakes than over streams or fields, and that activity is greater over rural areas with buildings than over uninhabited forest areas without buildings. Rain was found to depress the nocturnal activity of bats.
