Question

Why does a vibrating simple pendulum not produce any sound?​

Answer 1

Answer:

The frequency of vibrations produced by a pendulum does not fall under human ear's audible range, so we do not hear the sound produced due to these vibrations.If the air is an object then no, you can't produce sound without a vibrating “object”, but if the air is not an “object” then yes you can produce sound without a vibrating object. ... Sound is a form of energy that causes sensation of hearing. Our ears can hear a sound by receiving vibrations .
