MATLAB: How to disable beep (beep off does not work)

2013abeepsound

Hello Fellow Matlabbers,
I am using Matlab 2013a on OS X. The beeps being emitted by the editor are driving me crazy (especially while using headphones). After running "beep off" Matlab appears to believe that beeps are off:
>> s = beep
s =
off
However, when I type things like "case" or have partial parentheses I still hear beeps. Is there some other variable I can turn off? I really don't want to have to switch over to emacs as my editor, but these beeps are horrible.
Thank you, Kyle

You can change the the error sound file to something that does not have any sounds.
This way when anything that emits a beep fires, nothing plays. beep off only shuts it off for errors.
