Sound is what you hear! -
However, silly and meaningless that might “sound”, it is very much true. Though you might read that sound really is a form of “air-wave”, or a change in pressure throughout a medium, it can also be argued that it needs a ‘sound receiver’ to perceive that change and the most common receiver is the human ear. However, there are some airwaves that people cannot hear, but other living creatures can and there are even more airwaves that only special equipment and instruments can “hear” or detect.
