Question

distinguish between infrasonic and ultrasonic.​

Answer 1

Explanation:

Infrasound and ultrasound although sounding similar are very different in nature. The normal human range of hearing is between 20 and 20,000 Hz (A Hertz (Hz) is a unit of measure for frequency and is the same as cycles per second). Sound waves can be used to determine the distances and structure of some objects or tissues. Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz.

Answer 2

Answer:

the sound of frequencies lower than 20 Hertz are known as infrasonic sound. The sound of frequencies higher than 20,000 Hertz are known as ultrasonic.
