Has your computer made any strange pinging sounds today, but you can't figure out where it's coming from? The answer is probably Facebook. The world's most popular social networking site now makes a sound whenever you have a notification -- you know, for timeline posts, friend requests and more.  Luckily, the sound can be turned off by following these three simple steps.


Once you're logged into Facebook, go into your Notifications Settings.


Click View, which is located next to 'How You Get Notifications on Facebook.'

Facebook notifications settings


Remove the check mark from the option that says, play a sound each time a notification is received.


Now you can go back to enjoying some peace and quiet, and you won't get caught using Facebook while you're at work.
