Anyone ever notice on how Airbuses there is always this very "rough sounding" roar on takeoff as if the engines are going to self destruct any second? What is the reason for this?
Only occasionally hear it on a B737 (probably when they are using full power for takeoff) but never hear this sound (kind of like the sound a 4 cylinder car would make if you were steadily redlining the engine) on another Boeing, ERJ or CRJ aircraft.

Most of my travels are on Airbuses 319-320-321 and occasionally on 737's but don't recall ever hearing such noises, The airbus if anything whines a lot and the 737 seems to have more of a grawl.
Which airbuses were they.?

It's always a pleasure to see new and exciting forms of Airbus-bashing, innovative...and ultimately as nonsensical and useless as all forms of A (or B) bashing.
Well I never ever noticed such a noise, neither on B nor on A, but then I rarely fly Airbus...only about 150 times per year, throw in another 100 Boeing flights, so I don't really qualify to judge such "whiny, redlining, itsy-bitsy plastic" noises, which are produced, btw, by the engines, and afaik, Airbus does not manufacture any engines, neither does Boeing!

Just in case this isn't a new try to bash Airbus I want to add that I have also heard something...
I wouldn't describe it as a rough roar but there is definitely in front of the engines of an A 32x a specific noise which I haven't heard in a 737NG.
The first time I heard it was when I sat in front of the engines in (~7th row) an Aer Lingus A321.
But on the other hand I have noticed that 737NGs are much louder behind the engines.

Just to avoid misunderstandings: I did suggest deletion of THE WHOLE THREAD, not a single post, and I said it openly in my first post here. Other than that, I really do not care about who posts what, but in this case, I had the pre-easterly egg-finding urge to point out the rather A-bashing nature of the thread per se .
btw: as can be seen, I do know how to use smilies, so don't jump to conclusions, angry young man
Ignore threads? I do that most of the time, but not if it's against a clear regulation of the Forum, and A vs. B is such a regulation!
And btw: I didn't say it was a seen-it-all, on the contrary, it's rather innovative

This thread is not Airbus bashing - for some reason, I have noticed that there is a very distinctive low pitched noise when many Airbus aircraft take off - it is most peculiar. I noticed it on Sunday, watching an AF A321 take off at NCE. It sounded very different to the Easyjet 73G that had taken off before. It is not just Airbus narrowbodies either, AB3's have it too. It must obviously be some feature of the engines these aircraft carry, but it is definitely there.
P.S. I am most definitely pro-Airbus, this is not a criticism, just an observation.

On the baby buses I always find there is more of a wine at take off... I am normally in Business which is just in front of the engines, sometimes just in front of the wing or on top of the wing the noise can sound more aggressive.
I remember being on a Boeing 777 back in November and thinking the engines sounded like a grass cutter. It was on a British Airways B777, GE fitted. It was a very intriguing sound.

Im kinda glad they do make noise. I miss the old 707 and DC8 waterburners when noise was king. When they develop a total quiet jet engine, I'll go back to watching trains. The noise and smell is half the fun at the airport.
If two people agree on EVERYTHING, then one isn't necessary.

I think I know the sound we're talking about here... but I remember this sound only from older 737s, like -300s and -400s. I dunno what engines they use. IMO Airbuses sound rather like a vacuum cleaner from the inside.
But generally, this is not a question of A or B or C or whatever, it's a question of the engine.... Both Boeing NGs and Airbus use CFM56 engines and IAE engines. So it would be interesting to know on which engines you heard these sounds?
Isn't the sound the engines make on T/O the best thing in flying anyway? No matter if it's a huge PW4600 or a small CFM56? A or B?
And for Andreas... calm down. Mind your blood pressure.

Why is it that when an aircraft begins its take-off role, for the first few seconds the engine sound is 'low' then all of a sudden the power goes up so much? It is most noticeable on a 744. What is the reason?

Horus: I'm not a pilot, but I think the thrust levers are pushed forward to only 60% N1 thrust to see if the engines are ok and the readouts are the same for both (or all) engines. Then, if everything is Ok, they push the thrust levers to max or FLEX or whatever the pilots desire.
It also takes some seconds for the engines to reach their max thrust.
Again: I'm not a pilot and my apologies if I said something wrong

The sound you are trying to identify belongs to the engine turbine going to "take off" power. Otherwise, the jet engines are left in a "ground" power which provides enough thrust to get around on the deck.

OK I am not an engine expert...And I do fly a lot each year. I only fly for pleasure and still manage to fly about 50,000 miles a year. When CO had A300s in their fleet, I noticed that the noise inside the plane was definitely louder than any other plane I had flown. Even more so at take off. This is the major reason I like the less obtrusive sound level in the Boeing. Maybe because its cabin noise levels are at a lower decibel than in the Airbus.
Since I only fly on Boeing now because of CO, I can not say what the new Airbus sounds like. When I get the chance to fly one, I will most definitely be checking this out.
