Question

is it true that when vibrations are fast you hear a soft sound?​

Answer 1

Answer:

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. The fastest vibration we can hear is 20,000 times per second, which would be a very high sound.

hope it helps

have a great day

Answer 2

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. The fastest vibration we can hear is 20,000 times per second, which would be a very high sound.

Three things vibrate when sound is created:

1.the source object

2.the molecules in the air (or another medium e.g. water)

3.the eardrum
