Question

Explain how sound produced by a vibrating objects reaches your ears ? What happen after it enters the ear?

Answer 1

Sound is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles. These particles bump into the particles close to them, which makes them vibrate too causing them to bump into more air particles. This movement, called sound waves, keeps going until they run out of energy. If your ear is within range of the vibrations, you hear the sound.

Picture a stone thrown into a still body of water. The rings of waves expand indefinitely. The same is true with sound. Irregular repeating sound waves create noise, while regular repeating waves produce musical notes.

When the vibrations are fast, you hear a high note. When the vibrations are slow, it creates a low note. The sound waves in the diagram show the different frequencies for high and low notes.

Answer 2

A vibrating object causing air molecules to vibrate . when these are vibrations reach out,ear they are collected by the pinna and funnelled into the ear tube.
These then strike the eardrum which starts vibrating with the same frequency this causes the delicate bones of middle ear to vibrates. This simulates tiny hairs in the hearing organ which ,in,turns,send a single to the audiotory nerve takes the brain and we can the hear the sound.
