Do sounds add together to make louder sounds?

Phoebe asked the Naked Scientists:
   
If there are multiple sources of sound in a particular area - say 20 sources of air conditioning units, each creating about 60 Decibels of sound, does this create more sound (and a louder sound) in the same way that lighting multiple candles creates more light?

What do you think?

Q. Do sounds add together to make louder sounds?

A. Yes, with the exception of anti-phase sound, as used in noise cancelling headphones.
