These are the waves having frequencies (Vibrations/oscillations of particles) above those of audible sound waves-greater than about 20 kHz. Many animals have the ability to hear sounds in the human ultrasonic frequency range. A presumed sensitivity of roaches and rodents to frequencies in the 40 kilohertz region has led to the manufacture of “pest controllers” that emit loud sounds in that frequency range to drive the pests away. read less
