One possible source could be the brake cables rubbing against each other. And a possible solution is to apply a very little bit of chain oil where the cables touch.
This could also be improperly tensioned spokes on the front wheel. For me, it was more of a feeling or vibration coming up through the bike, but there was definitely a noise associated with it, too.
