Some early bat detectors used ex-Navy low frequency radio sets, simply replacing the aerial with a microphone and pre-amplifier. It is also possible to modify a portable Long Wave radio to be a bat detector by adjusting the tuning frequencies and replacing the ferrite rod aerial with a microphone and pre-amplifier.
Provides a comprehensive tool for analyzing and comparing high-resolution full-spectrum sonogram of bat echolocation calls recorded from time-expansion bat detectors. Sound Analysis Pro 2011 [9] GPL v2: Windows: Performs automated recording and analysis of animal vocalization. It can record, analyze and manage sound data over prolonged periods.
A heterodyne bat detector simply downshifts the bat frequencies by the amount shown on the dial or the display on the more posh detectors. For instance with a hockey stick call ending at 45 kHz, this will produce a near zero end frequency when tuned to 45 kHz, If it is tuned too low, or too high, the difference frequency rises as illustrated in ...
Bats are one of the world’s most enigmatic mammals, found in almost every country, yet best recognized for their elusiveness and mysterious nocturnal behaviors. The unique use of echolocation to ...
The bat detector records in full spectrum at 192 kHz sample rate and the files can be converted to zero-cross files in post processing. [5] The SM2BAT can record two channels simultaneously allowing a second microphone to be mounted up to 100m away from the recorder. With 4 SDHC cards the device can record about 240 nights of bat calls. [6]

Ultrasound avoidance is an escape or avoidance reflex displayed by certain animal species that are preyed upon by echolocating predators. [1] Ultrasound avoidance is known for several groups of insects that have independently evolved mechanisms for ultrasonic hearing.
A harp trap in Borneo. A harp trap is a device used to capture bats without exposing them to disentangling from traps like mist nets and hand nets.It capitalizes on bats' flight characteristic of turning perpendicular to the ground to pass between obstacles, in this case the trap's strings, in which flight attitude they cannot maintain their angle of flight and drop unharmed into a collection ...
