Question

KnowledgeBoat · Accepted Answer

Infrasonic sounds | Sonic sounds| Ultrasonic sounds | Supersonic sounds ------------------|-------------|-------------------|------------------ The sound of frequency less than 20 Hz is called infrasonic sound. |The sound of frequency in the range 20 Hz to 20 kHz is called the sonic or audible sound. | The sound of frequency greater than 20 kHz is called ultrasonic sound.| Supersonic sound refers to sound waves generated by a source that travels faster than the speed of sound in a particular medium. Infrasonic sound is produced by some animals (e.g. Elephants, Whales) and certain industrial processes. | Sonic sounds are within the range of human hearing. Day to day sounds that we hear like speech, music, and environmental noises are examples of sonic sounds. | Ultrasonic sounds are used in medical imaging, industrial testing and cleaning processes. Some animals, such as bats and dolphins produce ultrasonic sound for communication and navigation. | Supersonic sounds are produced by aircraft or bullet train travelling faster than the speed of sound and certain experimental situations.
