If we produce a sound more than 20mhz, can we feel noise or we will not listen totally?

Infrasonic wave- Below 20hz frequency (Dogs can listen it).
Audible sound-. 20 to 20000 Hz Human can listen only of this frequency range sound.
Ultrasonic-beyond 20000 Hz (man cannot listen to it but bats can listen to these sounds).

Scholars, how then can humans prevent the biological effects that may be induced by supersonic?

Infrasonic : sound frequency less than 20HZ.
Ultrasonic : sound frequency greater than 20kHz.
Supersonic : it is not the frequency range it denotes the speed of objects which have speed greater then the speed of sound i.e. 330m/s. It produces shock waves.
