Answer:
Ultrasound waves
Explanation:
Ultrasound is an oscillating sound pressure wave with a frequency greater than the upper limit of the human hearing range. Ultrasound is thus not separated from normal (audible) sound by differences in physical properties, only by the fact that humans cannot hear it. Although this limit varies from person to person, it is approximately 20,000 hertz in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.
Infrasound is a low-frequency sound. It is sound that is lower in frequency than 20 Hz (hertz) or cycles per second, the normal limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher
Hence, the ultrasonic waves are high frequency waves.
