very good demonstration - clearly the GTF is much quieter, really very impressive. Gives Better understanding of its benefits & much more confidence that despite some current problems the GTF has a bright future.

I love the old racket that the A321 CEO makes, but The NEO is definitely alot quieter

It depends on the engine as well, if you are on a NEO with PW1100 engine then it will be quiet. The CFM is way louder although it uses advanced material, but still it is still a conventional engine. PW engine was designed differently, they incorporated their engine with geared mechanism to achieved the ultra high bypass ratio while maintaining the performance power of the engine. Because of the Gear, they can make the outer fan rotate differently(slower) than the inner fan making it a quieter engine.

Silent is worser, I like sounding engines

Wow, what a difference. Amazing video! Exactly the video that I was looking for.

That sonic resonance from the talon x combuster of PW 1000 ❤ #whalesound this quieter geared engine is the result of a 20+ year-long research of nasa and PW. Amazing!

Wow, the GTF is nearly silent. The buzz saw sound coming from the CFM is the tips of the bypass fan breaking the sound barrier. This causes huge stresses that need to be mitigated. The gearing allows larger but slower moving fans that increase efficiency.

do you think that the buzz saw sound from the CFM is because of that? I have no idea, but I don’t really think so… they lose so much lift and generates a big amount of drag if the speed is supersonic

Great video! That GTF sounds like a watered down version of a PW4000 from a 777! Of course! That's the main point of GTF! The fan spins slower than the compressor; therefore it requires less fuel.
