The human ear is sensitive to sound waves of frequency between 20 Hz to 20 kHz.This range is known as audible range and these waves are known as audible waves. Some animals like dolphins, mice, dogs, and bats have a high- frequency limit that is larger than that of the human ear & thus can hear ultrasound. Infrasonic is sound with less than 20 hertz and ultrasonic is are more than 20000 hertz. Ultrasonic waves are those, whose frequencies are above the frequency range of human ears (normally 20kHz). Difference between the following term Supersonic and ultrasonic 2 See answers Answers rahulrai81 Ace; Explanation: Ultrasonic waves are acoustic waves that are so high in frequency that humans can't hear them; however, infrasonic waves are sound waves that are lower in frequency than what humans can hear. Both systems apply voltage to piezoelectric transducers which will vibrate at high frequency in an up and down motion. Subsonic missiles are slower than the speed of sound. Ultrasonic waves are waves that have high amplitudes. *Response times vary by subject and question complexity.
