No System Beep

I found the following file on my laptop recently:

I'm traveling by plane from San Jose to Philadelphia. It's just me and my laptop (no network) so I'm poking around for things to do.

No System Beep:

I've got some audio files which I'm playing through my headphones but every time I type C-g in emacs a very loud beep hurts my ears...

 sudo xset b off

ahhhh. OK now back to my wanderings.
