The science of sound

 

The text shows some curiosity about sound and among them are: what is the sound, different types of sound and how we hear sounds. When an object vibrates, it causes the air particles move around rapidly and this creates a chain reaction and it is this kind of chain reaction that generates an energy called sound. The sound is considered a mechanical energy as it propagates through matter in space and depending on the composition of matter the speed of sound in that environment just changing.  when the vibration of air gets in our ears, reverberates in the inner membrane and bones of the ear canal, bringing this information to the brain, and so are able to hear the sounds around and identify all kinds of sounds.
