While dogs are often touted as man's best friend, cats can be so aloof that they seem like little more than a passing acquaintance. However, there's more going on between felines and their human owners than a cat's sometimes steely exterior may suggest.
Hearing a recording of your voice can be an unpleasant experience, as the sound isn't usually what you expect. To put it simply, hearing works by something called "air conduction," in which sound waves travel to our ears' cochleas, which in turn stimulate nerve axons that send signals to the brain — but that's not what happens when we speak. While some air conduction occurs when we hear ourselves talking, most sound is translated through "bone conduction," particularly our skull bones. This blend of both air and bone conduction gives our voice a deeper, richer low end, which explains why most people perceive their voices as higher-pitched when listening to a recording.
