The audio includes a "ticking" sound every second as the frequencies switch, which is intended to prevent rodents from habituating (getting used) to a single tone.

At 11.5 hours , the track is meant to run overnight or during work hours to provide continuous coverage. Critical Limitations and Science While the theory suggests these sounds create an
This is the threshold of ultrasound, generally inaudible to most adults but well within the hearing range of mice and rats. The audio includes a "ticking" sound every second
While the theory suggests these sounds create an "unbearable" environment for pests, real-world results are often underwhelming:
These are technically "high-frequency" rather than ultrasonic (which begins at 20kHz). Younger humans with sensitive hearing may find these frequencies highly irritating or even painful.
