Hi, my name is Arthur and today I'm going to teach you a little bit about sound waves.
See those cars? When turned on, they emit waves that hit our eardrums forming a sound.
But it's not just cars that produce sound waves
See that dog? When he barks he generates the barking sound that is also a sound wave.
Hi, how are you?
We humans can listen in the 20Hz and 20000Hz frequency range
I think you understand, that's easy, isn't it? Thanks for your attention and see you next time
