MacBook Pro Beeps

[John Doe 57]

Yesterday I heard a beep sound from my computer. I happened again today. It is just one quick beep. Any ideas of what it could mean or is it nothing to be worried about?

On startup or at random points while the computer was running?

Just at random points while running.

The above link, contains audio of the same beep I am witnessing. I am however not witnessing clicks or nearly as many beeps as in the video.

Hopefully its nothing big, considering it seems Apple hasn't been able to fix the problem for nearly a year.
