Within in each discipline of game making there will always be words that seem obvious in explanation but then science gets in the way and come to find out the word means something different. Audio is no exception and the word has, to my count, a 90% chance of being wrong when asked to define it. It's such a sure thing that I don't think any audio professional would take me up on a $5 bet. The word I'm talking about is Psychoacoustics.
