Have you ever thought about what the world would be like without sound. I think it would be boring and silent. It would be like losing something very special because sound is very special in our lives. We use sound as a way to communicate and to listen to music.
Sound is made by anything but how does your brain know it is sound. Sound is a vibration. As it’s vibrating the air molecule bounce of then hits in your ear drum and then converts and goes into your brain and then your brain notices it is sound.
What makes sound different? It makes it different by the pitch. Pitch is high and low sound. They are different volumes. You know that the pitch is high when the sound waves are small. And how you know what the low pitch is when the sound waves are big.
There is no sound in space. Because the is no air for the air molecules to make sound. So in space there is no sound cause no air for air molecule to be able to make sound.
So without sound in this world would be wired, different, boring and quiet. I think sound is a big part of our lives.
