Bat Detector Box
Bat Detector Box, this box is used to detect the presence of bats by converting their echolocation ultrasound signals to audible frequencies usually about 300 Hz to 5 kHz. Bats emit calls from about 12 kHz to 160 kHz, but the upper frequencies in this range are rapidly absorbed in air. Bats use echolocation which is the use of sound waves and echoes to determine where objects are in space, bats send out sound waves from their mouth or nose. When the sound waves hit an object they produce echoes. So when it gets a bit warmer I will be out there listening for them, And Pauline if you see this I still have your bat box and it’s still ok thanks.
