Sound waves with frequencies below 20hertz are called infrasonic, while those with frequencies above20000 hertz are called ultrasonic
ultrasonic sound waves
The sound waves which are below the audible sound are called infrasonics(<20Hz) and The sound waves which are above the audible sound are called ultrasonics(>20KHz).
used for forecasting natural disasters and they are also used in therapeutic devices to treat the people with physical illness :)
infrasonic
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)
So that you can have fun in the water.

With special technology, yes
Sound waves at frequencies lower than humans can hear.
Infrasonic.
Sound waves with frequencies below 20hertz are called infrasonic, while those with frequencies above20000 hertz are called ultrasonic
We cannot hear earthquakes from our ears. It is because the waves produced are infrasonic.
The definition of infrasonic is relating to sound waves with a frequency below the limit of human hearing, 20 Hz. Ultrasonic relates to sound waves with a frequency above the limit of human hearing, 20,000 Hz.
Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics
