The V2500 is the quietest engine on the A320.

The CFM56 is a little louder.

What about in terms of All Turbofans produced.
Is V2500 still the most silent.

Yes,most likely!
Our MD-90's have the V2500 engine,and they are more silent than any other airplane at OSL,ARN or CPH.

Nope.

The BR715 is a quieter engine.

But as far as ALL turbofans, I don't know. The Canadair Regional Jet's engines are supposedly the quietest in the aviation industry, but I hear them flying over my head a lot louder than a TWA 717 with the BR715 engines.

Max Power forgot squeeze. Adds another just like.........Never mind.
Noise measurements can be difficult. I hear MD-80s and 727s take off all day long. I can hear the MD-80 for a long time after takeoff but the 727 only about half as long. The MD-80, however, is considered a quieter aircraft.

The Honeywell LF507 engines that power the Avro RJ are the quietest airliner jet engines in the world.

The new Avro RJX will be powered by Allied Signal/Honeywell AS977 engines which will be a tad quieter than the Honeywell LF507 engines.

However, the V2500 engines are extremely quiet.

You'd have to get an acoustic engineer to test 'em all under same controlled environment to know for sure. Having had my first encounter with a B717 (Hawaiian Kona-HNL), it is my opinion that the 717's BMW/RR engines are definitely the quietest when compared to the V2500 (second quietest) and CFM56 (third place). It is also has the lowest available power (on the lightest aircraft) and the lowest fuel consumption (for typical operations). The V2500 and CFM56 are used on more comparible aircraft and the V2500 has more power while the CFM56 uses less fuel.

Heck, everything's a trade-off in aircraft design world.  Big grin

Err,

AAR90, wasn't one of the V2500's selling points on the A320, the fact that it consumed LESS fuel than the CFM56? Just clearing that up.

On the other hand CFM says its engine has less maintenance costs and emits fewer pollutants.

Cheers,

Justin

I have no idea what "selling points" there were/are for any airliner.... I don't buy airliners.  Wink/being sarcastic

The information I provided was based upon personal observations and interpretations from having flown aircraft with both engines on multiple similar flight legs under similar environmental conditions. Unfortunately, the differences in airframe performance can easily override any observed/perceived differences in engine performance. If one can find same airframe/different engine combinations to make more accurate observations with, it would be interesting to see/discuss. Until then, this was the best info I can provide. Sorry.

I've also heard that the V2500 is quieter than the CFM56. It seems that the V2500 is more fuel efficient:

V2500 Cruise SFC: 0.575
CFM56-5B Cruise SFC: 0.596

However, as was said (and CFMI will quickly point out), the CFM56 has evidently been historically easier/cheaper to maintain, hence lower operating cost than the V2500. Take your pick I guess...
