Sound

A world without any sound would be strange and silent. We wouldn’t be able to enjoy music and people would find it difficult to communicate. It would be boring. Sound helps us in many ways, but what is sound?

                                           

When you hit a metal bar it vibrates then goes to your inner ear, travels to your ear drums and converts into a electrical signals and to your brain.

When music is played loud, the speaker vibrates and goes to your ear and makes your eardrum vibrate. Sound waves can be different to another there is a high pitch and low pitch,

the point is the peak and the bottom is the trough.

Sound works by anything like a bang on table, tapping, knocking, all sorts of  things that make sound. We can not hear sound in space because there is no air molecules to vibrate.
