sounds on my new macbook? help

[rocafella]

hi all, i have purchased a new macbook 13inch black, and every now and
then it gives a sound "ping ping ping".

i really have no clue where it comes from...i have only installed
microsoft office on the macbook and while entourage runs it comes up
with that sound too.

can anybody help me on that?

regards
peter
