Test that your ultrasonic microphones are performing correctly


Ultrasound is beyond the range of human hearing, which means it can be difficult to test your bat recording system. Wildlife Acoustics' Ultrasound Calibrator is an indispensable tool to verify the performance of SMX-U1 and SMM-U1 microphones.

The tester can also emit ultrasonic signals to the Song Meter while it is recording, to verify that the system's settings are appropriate. This test is helpful when comparing bat activity across habitats or for unique deployment situations.

The Calibrator has two modes of operation: “Calibration” for testing mics at close range and “Chirp” to test the functioning of the entire system from a greater distance.

Key Features:

  • Test your ultrasound microphones
  • Test functioning of entire SM2BAT+ system
  • Compatible with SMX-U1SMM-U1, SMX-US, SMX-UT and SMM-U2 microphones
  • Powered by 1 x 1.5V cell battery (included)

WARNING: In "chirp" mode the calibrator emits a 40kHz signal at over 100dB. Prolonged exposure to ultrasonic signals can damage your hearing so please do not place the calibrator close to your ears.

Please note: that the user guide supplied with the 'calibrator' tester only applies to the SM2BAT and EM3. For use with an SM3BAT or SM4BAT recorder please refer to the Calibration Mode Microphone Testing section in the SM3BAT or SM4BAT user guide.
