Disabling beep when moving between desktops

OpenSuSE 11.0
KDE 4.0

They might be unrelated, but the system beeps are driving me insane. When I move between desktops it has this god awful beep I can’t figure out how to disable. Also, in konsole, if I try to backspace when there are no characters to delete it gives me a different, but equally annoying, audible beep.

If I got the wrong forum I apologize, wasn’t sure which one to throw it in, though this one seemed a likely candidate.:X

A mite on the belated side, but thanks a bunch for the answer.
