Yes, Sound is vibration
Everyone knows what sound is. Even those who are deaf or hard of hearing understand the concept of sound. However, many people have no clue as to the way sound functions. After all, can you say what sound actually is? Most people can only answer “the stuff you hear”, and fall short of being able to give any more detail than that.
There’s no shame in this. Not everyone is a scientist, after all. Not all people are going to have any idea how to quantify something that they take for granted. If you’ve always been able to hear sound, then you have no reason to question how it works. You can hear it, you know it functions, that’s all you need to know. However, the world of sound is actually an incredibly interesting world. There are so many interesting facts and details involving sound, lyrics, and acoustic waves that you’ll wonder why you never really looked into it in the past.
