The Quietest Airliner=?

Tue Mar 27, 2001 6:26 pm

I recently flew to Boston on an A340, and was very astonished of the high noise level during the whole flight. I was sitted in the middle of the cabin. Last month my mother flew on a new 738, and she told me the noise was terrible. On the opposite, I have the feeling a 777 is quieter than a 738 on take-off, but I haven't yet flown on that model.
Are there statistics of noise levels on board, and "outside" during take-offs for each airliner?

As far as I know, the A340 is the quietest airliner presently flying.

I would be interesting to have the ratio:
noise(dB)/MTOW of airliners...
Because it's sure that a B717 makes less noise than an A340...!
Anyone has information about it?

The A340 is the quietest airliner I´ve ever been on. And its also by far the most environmentally friendly widebody from the outside, too. A 777 is very loud in comparison.

Na,

Believe me I like the A340 and flew with this AC but honestly I don't think that
the 777 is "very loud in comparison"!!! I think they are quit similar!

The A340 is reffered to as the quietest cabin in the air Smile/happy/getting dizzy.

Well, I haven't flew A340 or 777 so cant tell. Accordingly to my flying expierence, I would say MD80 is the quiet plane of all I flew on - I was in the front section so might be the reason.

no question - front of cabin in a md-80 is very quite for the obvious reason that the engines are so far back. The last few rows, however, are quite loud for same reason....

If you think that an A340 is lound, your eardrums will be bleeding in a 737-200 or DC-9.

I dont think 737-200 or DC-9 that loud (well if you sit beside engine in DC-9, then you're right).

I think Fokker jets are worse. Propellers are even worsen.

I enjoy feeling against the wall of cabin during flight. I just like to feel the vibration when on cruising and from APU on ground while boarding.

The quitest aircraft are the MD-90 with there V2500 engines, and the 717 with there Rolls Royce BR715.
I know this because I have an MD-90 design overview manual from McDonnel Douglas.

The 340 is one quiet, smooth ride. This from someone who has ridden all Boeing widebodies -- the 747-100, 747-200, 747SP, 747-400, 767-200, 767-300, 777-200... there is no comparison to the ol' slowass bus.

The MD-80 is also one of the quitest.

Ejay you are right like I said the 717 is very quiet along with the MD-90. The question was airliner not specific by widebody narrow body etc.

The quietest is the BAe 146/Avro RJ. Its nicknamed "Whisper Jet".

If anybody has varying information that they can substantiate then I'd be interested to hear it.

Right BA, externally nothing beats the whisper jet, BAe 146/ARJ. Internally, however, it is quite avarage.
It all depends on where you sit.
For quietness hardly anything beats the front of the MD-80 or -90. (I assume that the 717 has the same qualities, but haven't experienced yet). But they are really bad in the far back. Even the DC-9 is very pleasant up front, but a quite extreme pain in the back, especially when you experience a crew who doesn't care about engine syncronization.
The only thing worse is the back of a 737-200 during take-off - pure thunder, but unlike the MDs it calms down to bearable levels when it accellerates to speed.
A few years back I invited a friend - a cityzen of the former Soviet Union - on a trip to Paris on an AF 732 - sitting in the back. He had flow hundreds of flights on all the most noisy Russian airliners except the Tu-104, and he was eager to experience a "quiet" western plane. He was shocked, he had never heard anything as loud as the 732 taking off. We flew back home on a 735, a very different story.
The 757 is really pleasant all way along the cabin, but pilots complain that the cockpit is rather noisy.
But who cares about a little noise on the short jumps? In between the engines on a DC-9 is a little too much for me, but otherwise what counts are the long distance intercontinental flights. Strong noise for many hours is tiring, but otherwise it is just pleasant to know that the engines are spinning, isn't it? Try a Caravelle, and it will not leave you in any doubt.

I think BA is right with the quietest. I remember hearing on TV that the BAe 146 was the quietest.


Dont you just love sitting in the last row of a D9S? Nothin better than no window and metal fan blades spinning faster than the speed of sound, 12 inches away from your head!! (Ive done it before).

The stats I gave were for cabin noise levels. The Avro Rj series is indeed externally very quiet but quite ordinary internally, particularly when the trailing edge slats are deployed. I've flown it many times. My quietest internal experience was indeed the MD80. I could hardly hear the engines on takeoff.

I found the A340 to be very quiet. I think the quietest is the 777

Yeah, I've flown on the Avro RJ 85 (might have been 100) on Crossair and the Avro RJ 100 on CityFlyer Express. They are quite nice planes. Nice and quiet. Inside, there not the quietest plane in the world, but still quiet.

Outside.............its dead on quiet. I was once spotting at Denver, and watched one takeoff, for a second there, I wondered if it was using 100% throttle or not.  Smile

The Quietest Airliner in the DC9 Family is the DC-9-95 (717) It is a Whisper Jet

The Quietest Airlines in the Airbus Family is the A340

The Quietest Boeing is the B777

Are we all happy now?

After sitting in the last row of a 727 a long while back I have never complained of noise. I was still hearing the engines in my head while in the airport. It was loud!

I was on the back of a DL 727 from SFO-SLC maybe 3rd to last row? Not sure, right next to the galley, but it was a nightmare. I couldn't even talk to the person next to me it was so loud. Funny though... when we got to SLC the food truck pulled up on the wrong side of the aircraft and started knocking on my window.... I put my hands up like i didnt know what to do and he just kept staring in and knocking. Finally we got up to get off, and the flight attendant (I have no idea how) folded down the seat, opened the emergency exit and let the man in

When saying that you found an airliner quiet, it would be important to specify where you were seating; First class is quiet in any airliner, even the 742...
The A340 is certainly not the quietest plane. A 777 take-off is very impressive: you can hardly hear a whispering!

All airlines that fly the A330/340 series claim to have the quietest cabin in the sky because thay are the quietest wide body jets. This has been proven. Sorry 777 lovers. In actual fact the quietest cabin is the trent powered A330 as I detailed in my earlier posting.
Having said that I've flown A340 and 777 both foreward of the wing and the most impresive was Malaysian 777 powered by Trents. It was the smoothest quietest take off I've ever experienced. BA 777's powered by GE90's was nowhere near as impressive - noisy & cranky. RR's certainly make the quietest engines.

When someone writes the 777 is quieter than a A340 its simply untrue. Are you working for Boeing? I fly quite often and I´m also at the airport about once a month to photograph and I know for 100% that the 777 is clearly louder at take off than a A340. Inside its the same as I wrote before.

Having flown the A340-300 about 40 minutes after the 777-200, I can confirm that the A340 is noticeably quieter than the 777, however it isn't all that much. However, there is a noticeable difference between takeoff & climb thrust, whereas it seems much of a muchness in the 777 (RR Trents). The A340 also sounds slightly different depending on what N1 is being used on takeoff, at low takeoff N1s it sounds similar to an A320 (with that characteristic buzz).

The 717 is definately a quiet bird, given that it doesn't have to pay the noise surcharge at SYD, the only other airliner that qualifies for this is the BAe146.

Cheers,

Justin

My flight FRA-MUC today was surprisingly on Lufthansa´s A340-300 D-AIGL (obviously a positioning flight). Sitting in Economy (but paying Business - the flight was full!) over the wing the A340 even seemed quieter than I remembered it from before. The whole flight including starting and landing was so smooth that the return flight this late afternoon (came back 2 hrs. ago) in the usual A300 seemed like driving on a John Deere tractor, bumpy and noisy.

When I fly the 777 on United from MIA to DEN, the takeoff was LOUD. VERY LOUD! Then again I was sitting behind the wing. It was so loud that the cabin wall next to me was vibrating so much.

But I like noise. Big grin

I really wouldn't know how loud the widebodies are, because every widebody I've ever flown on has been up in the front. One of the times I flew on a DAL 777, I was in the last part of the second Business Elite cabin right by the engines, and it was a fairly quiet ride. But the 717 is indeed the quietest airliner. I was amazed the first time I flew on one. After having flown on some many DC9s, I was quite amazed about how quiet takeoff was. For the first time ever, I didn't have to repeat my drink order in flight. And you can hold a conversation in the last rows without yelling it's so quiet. But of all the airliners I've ever flown on, the noisest was the EMB-120, that's one loud plane.
