How to stop/reduce ultrasonic sound wave device?

In summary, to stop or reduce ultrasonic sound wave devices, one can employ several strategies: moving away from the source, using soundproofing materials to block the waves, adjusting the device settings if possible, or utilizing white noise machines to mask the ultrasonic sounds. Additionally, consulting with a professional for effective noise control solutions can be beneficial.
