Wildlife Acoustics Ultrasonic Microphone Calibrator
Product code: SM2_CAL
Print
Since ultrasound is beyond the range of human hearing, verifying proper system and microphone performance can be a challenge. The Ultrasonic Calibrator allows testing of both the microphone performance and the full SM2BAT+ recorder system performance.
The Calibrator has two modes of operation, “CALIBRATION” and “CHIRP”. Calibration mode is used to test the microphone unit itself at close range and the chirp mode is used to test the entire system at a greater distance.
WARNING: In “Chirp” mode, the Ultrasonic Calibrator emits a 40khz signal at over 100dB SPL. Prolonged exposure to high intensity ultrasonic signals may cause permanent hearing loss at audible frequencies. Please do not place the Calibrator close to your ears!
