WebbWe hear sounds because the vibrations in the air cause our ear drums to vibrate, and these vibrations are converted into nerve signals that are sent to our brains. Similarly, microphones detect vibrations in the air and convert them into electrical signals. When you imagine a sound wave, you might think of something that looks a bit like a ...
