A380 Noise Levels

Wed Dec 13, 2006 2:40 am

Does anyone have any information on the certified noise levels of the A380?

Thanks  Big grin

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.

It was silent at LHR and FAB. Even when it went over my house the A380 was quiet and I only noticed when the sun reflected against it and almost knocked me out. Big grin

Also now after EASA and FAA approval its the most quiet plane in the skys.

As enthusiast im sure i would like, it would do more noise with the lovely RR sound from the Trent's . Big grin

It is not the quietest airplane in the sky. The MD90 and V2500 powered A320 are the quietest in the sky.

Having seen it many times in the circuit, it is very quiet indeed.

(Also in terms of cabin noise, I understand that it is also extremely quiet from the reports of the ELF pax).

Actually the Eclipse 500 is the quietest jet in the sky... as for the quietest plane, I think a few sailplanes might have something to say about that

Corey07850 - Don't be foolish. Comparing the Eclipse and an MD90 or A320 noise levels is the equivelent of comparing a pedal bike and a car.

The A380 is not the quietest widebody either. It may be the quietest jet over 1 million pounds, but wait its the only jet over 1 million.  Big grin

I would imagine A345/346 would be slightly quieter, and the 787, with its GEnx (and likely the Trents too) will best it... with A350 sure to follow.

Of course, that's the point I was trying to make...

But in all reality, the Eclipse 500 IS the quietest jet aircraft ever made... A TO dBA of 54.9 decibals!

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.

Airbus has already announced that the interior noise level of the A380 is lower than the target for the 787...And it is sure quieter than the A345/6.

I know this is about exterior noise levels, but it might provide an indication...
Exceptions confirm the rule.

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.
