Natural sound

Natural sound is as essential as visual information because sound tells us about things we can’t see and it does so while our eyes are occupied elsewhere. Natural sounds reflect the complex interaction of natural objects; the way one part moves against another, the material of which the parts are made. Sounds are generated when materials interact and the sound tells us whether they are hitting, sliding, breaking or bouncing. Sounds differ according to the characteristics of the objects and they differ on how fast things are going and how far they are from us.
