Sound and life

Everyday, there are lots of things happening around us, and almost all of them have sound. We make sound through our body or contact of our body. We are also surrounded by all sorts of sound made by the environment. All the sound are part of our daily life. We usually use camera to take photo or video to record our life. If we can record the sound, that is another way to record our life but not visually. But human brain can't realise or record all of them, we are always missing a part of the sound which happening around us. By using a sound recorder, we are able to record almost all the sound around us in order to record our life.
