Fakalofa Lahi Atu! My name is Neomi and I am a year 8 student that attends Pt England School. Today I will be explaining to you what sound is and how we hear it. I will also be giving you some facts about sound!

First of all, let’s see what sound is! Sound is basically everywhere you go. The larger the vibration the louder the sound, sounds can be louder or softer, higher or lower. Our ears can hear differences in sounds and we can make sound by actions such as striking, blowing, plucking and scraping. Now that you know what sound is, I will now explain to you how we hear it.

Next, we are able to hear sound when an object vibrates that causes a movement in the air called a sound wave that travels to our ear canal, it then hits the eardrum that senses the sound and causes the three tiny bones known as Malleus, Incus, and Stapes.
Those three bones’ are responsible for amplifying it towards the Cochlea which is a shape of a snail’s shell yet the size of a pea?!

Finally, here are some facts about sound! Did you know that your ears don’t stop hearing when you’re asleep, your brain just chooses to ignore the sound. Another fact about sound is that the loudest natural sound on earth is caused by an erupting volcano.And lastly, the number 1 cause of hearing loss is exposure to excessively loud sounds.

In conclusion, sound is everywhere and your ears are very unique to be a part of your body.
