Are the operational noise levels of the A380 already available? I heard it is pretty quiet for its size, but what about its absolute noise levels? Is it louder than a 747?

Do you mean the noise footprint on the ground ? I highly doubt it would be bigger than the 747´s one.



Exceptions confirm the rule.

I thought I read that it was actually quieter ... at least with the current engines  Smile

The A380 is significantly quieter than the 747.

Its even quieter per pound of MTOW than the 777-200ER, and meets stricter QC levels if I'm not mistaken.

You'd imagine it would be with newer technologies and newer engines.

Keep in mind that noise during landing is also a big factor. A time when engine settings are lower. Plus what power setting an engine is at also is a factor in the noise it makes, Just take the A320. At Idle on the ground the V2500 VERY quiet compared to it's CFM-56 sister. But on takeoff both are pretty equal, and anyone worth their salt can pick out a V2500 flying overhead, Hell my feiace can and she wouldn't know a A320 from 707 by sight. (I'm working on that)

I heard that the 380 is rather quiet. Since the engines on this plane are rather huge, they are much quieter then the 747. Typically, the larger the jet engine, the quieter it is due to the fact that it spins at a slower RPM.

Yes, but the MD11 is still pretty loud compared to the much smaller A320, so while its relatively quiet for its size, it still makes a lot of sound, therefore I am really curious about the noise levels of the A380...

The "A380 Airplane Characteristics for Airport Planning" document has one answer.

http://www.content.airbusworld.com/S...a/docs/AC/DATA_CONSULT/AC_A380.pdf

Check section 6-2-1.
