VERY annoying especially when listening to sensitive music/movies...How do I shut that volume SQUEEK sound?

System Preferences - Sound - Sound Effects - Play feedback when volume is changed

if you want to have the "squeak" sound always on but temporaily mute it you can hold the shift key. theres also shift+option.
