Narrative:
During cruise flight both captain and first officer notice a loud humming sound and high frequency vibration coming from under the cockpit and a faint electrical odor. Soon thereafter; the purser called from door 1L reporting a loud whine and an odor that the passenger noticed as well. The vibration got louder then stopped and was accompanied by a vent extract fault ECAM (an avionics cooling fan) and its associated circuit breaker popping. Following discussions with the flight attendants; captain; first officer and dispatch the decision was made to divert. We declared an emergency and were cleared direct and landed safely in VFR conditions.
