Answer:
Three things vibrate when sound is created:
Three things vibrate when sound is created:the source object
Three things vibrate when sound is created:the source objectthe molecules in the air (or another medium e.g. water)
Three things vibrate when sound is created:the source objectthe molecules in the air (or another medium e.g. water)the eardrum
Three things vibrate when sound is created:the source objectthe molecules in the air (or another medium e.g. water)the eardrumWhen a sound is produced, it causes the air molecules to bump into their neighbouring molecules, who then bump into their neighbours, and so on. There is a progression of collisions that pass through the air as a sound wave.

The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second).

The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second).These vibrations enter the outer ear and cause the eardrum to vibrate too. We cannot hear the vibrations that are made by waving our hands in the air because they are too slow. The slowest vibration our human ears can hear is 20 times a second. That would be a very low sound.

Cats can hear even higher frequencies than dogs, and porpoises can hear the fastest vibrations of all (up to 150,000 times per second).

Answer:
no, this sound be audible to human beings because the audible range of human beings is 20 - 20000 Hz.
it is known as Ultra Sonic sound waves.
