One thing I can say is that it is VERY quiet! When it was at JNB recently it taxied past where we were standing and it was whisper quiet, compared to an AF 777 that landed just after it. Later when doing circuits it was also very quiet, take off was quieter than any other commercial airliner I have seen.
After Monday and Tuesday even the calendar says WTF...

The A380 generates very little noise because the plane has to meet the UK Civil Aviation Authority (CAA) Quota Count 2 noise standard for almost around-the-clock operations from London Heathrow (LHR), which is even more strict than the upcoming ICAO Stage IV noise standard.
To achieve this, the Trent 970 and GP7270 engines use very large front fans that turn slower than most high-bypass engines, which drastically reduces overall noise from the plane.

Corey07850 - This thread is about A380 noise. Nobody cares about an Eclipse 500.
A342 - Interior noise levels will not tell you anything about exterior noise levels unless exterior is VERY loud.
RayChuang - Heathrow has already stated that their noise monitoring equipment has shown that the A380 is 15% quieter than a 747-400. Thats not the 50% quieter that Airbus claimed it would be and whats all this talk about a noise abatement kit they are rushing to certification in hopes it can be delivered on the first airplane?
From all the press releases from yesterday their is no claim of meeting QC2. With all the bad press they have had lately I would think Airbus would be waving that flag of victory with a passion if they truly had it.
