How does an ultrasonic rodent repeller work?
Ultrasonic Rodent Repellers emit high frequency ultrasonic sound waves between 32 and 62 kHz to create an acoustically hostile environment that repels rodents from sound-protected rooms. It’s kinder than traps, safer than poisons, and completely inaudible to people and non-rodent pets. Unlike traps and poisons, the Ultrasonic rodent repellers minimizes human contact with disease-bearing rodents (no dead rodents to dispose of). 2. Why can’t I hear the Ultrasonic Rodent Repellers? Ultrasonic sound is a frequency too high to be heard by the human ear (your eardrum can’t vibrate fast enough). People can hear sounds ranging from 20 to 20,000 cycles per second, while dogs and cats can hear up to 27,000 cycles per second. The range of other animals can be even higher. When measured electronically, these frequencies are expressed in “hertz”, defined as a unit equal to one cycle per second. Ultrasonic sound waves are frequencies over 20,000 hertz, or 20 kilohertz (kHz). Ultrasonic Rodent Repell
