Mice and rats have a much broader hearing range than humans, extending well into the ultrasonic spectrum (up to 70–90 kHz).
These frequencies transition into the ultrasonic range. To a rodent, these sounds are akin to a loud, relentless siren. Because rodents use sound for communication and predator detection, this "acoustic stress" makes the environment feel unsafe and uncomfortable. The Benefit of 11.5 Hours Mice and rats have a much broader hearing
The extended duration is the most critical feature. Short bursts of sound are rarely effective because rodents are adaptable; they will simply hide until the noise stops. An 11.5-hour loop covers the entire duration of their peak nocturnal activity. By maintaining constant pressure through the night, the audio disrupts their ability to forage, communicate, and nest, eventually forcing them to seek a quieter habitat. Best Practices for Use Because rodents use sound for communication and predator
The volume needs to be high enough to fill the room, but be mindful of pets. Dogs and cats can hear these frequencies and may become stressed. but be mindful of pets.
Use this audio in conjunction with physical barriers. While the sound drives them out, sealing entry points with steel wool or caulk ensures they can't return once the audio is turned off.
