Bats that can detect 200 kHz cannot hear very well below 10 kHz. [25] In any case, the most sensitive range of bat hearing is narrower: about 15 kHz to 90 kHz. [25] Bats navigate around objects and locate their prey using echolocation. A bat will produce a very loud, short sound and assess the echo when it bounces back.
A heterodyne bat detector does not give a very accurate measurement of the frequency of a bat call, One reason is that the call frequencies can easily vary by 1 kHz or more due to the doppler shift. To track these changes and to get a more precise frequency, a frequency division bat detector or a time expansion bat detector is used using a ...
⭐ Bats use echolocation to "see" in the dark by emitting high-frequency sounds and listening to their echoes. This gives them an incredible ability to navigate their environment, locate prey ...
A heterodyne bat detector simply shifts all the ultrasound frequencies downward by a fixed amount so we can hear them. A "heterodyne" is a beat frequency such as can be heard when two close musical notes are played together.

It you have them, they’ll stay a while. Because once roosting season starts, bats can’t be extracted from homes. Yes, bat roosting season is a thing you need to be aware of.
The idea that moths were able to hear the cries of echolocating bats dates back to the late 19th century. F. Buchanan White, in an 1877 letter to Nature [4] made the association between the moth's high-pitched sounds and the high-pitched bat calls and wondered whether the moths would be able to hear it.
