Cabin noise comparision A330 / B787 / B777

Thu Sep 28, 2017 8:21 pm

Hi guys,

I recently flew with Norwegian on a B787-900 and was amazed by the relative quietness of the cabin.

I'm curious to compare the cabin noise of the following acfts, if someone has the datas, please shoot :
- B777-200ER
- A330-200
- B787-900

Thanks,

The B777 & A330 are noisy aircraft in the cabin. Of the newest generation it's louder 787 -> A380 -> A350 quieter IMHO.

The B777 is for sure the loudest, followed by the A330 which is quite a bit more quiet. This is then followed by the B787 of course

As long as you're behind the wings, the A330 is super quiet.

The A330 is relatively VERY quiet. Much much quieter than a 777 or a 747. Give me an A330 any day over a 777! Even the old A340 is a relatively quiet aircraft.
Given; the new designs are way quieter, the 787 and A350 particularly, but I also find the A380 super quiet.

I find it to be the complete opposite: if you're behind the wings, you have the blast from the engines which is much noisier than if you're front of the engines typically. This is especially noticeable on the 777.

Noise is very much dependent on the perception of the listener.

Some will be upset with the buzzsaw noise coming off the turbofan, others with rotor-stator interaction and yet others with jet noise in the wake. So sitting in different locations on the same aircraft would lead to very different experiences never mind when you change aircraft and position.

While you can measure EPNdB (Effective Perceived Noise) to try and account for this, it never really can.

The 777 is horrible. I got tinnitus on a AF 777-300ER while sitting next to the engine. When the engines got started there was infernally loud sound from the procedure. Having flown both the A330 & A340 the latter is quieter.

I agree (to some extent). I find the GE90 particularly bothersome during cruise. For some reason noise levels do not seem to diminish as much as on the PW or RR variants, when the engines are set @ cruise thrust after climb..

..maybe you mean 'ahead' of the wing? The jet wash noise is a lot more pronounced after the wing.

The 787 entirely depends on where you’re sitting. Near Door 1 and you’re approaching A380 levels of quietness, however around Door 3 it's louder than a 777, especially on the ground!

Yes, maybe... but trust me: everyone will agree that a Dash-8 is a VERY noisy flying machine, and that an A380 is quiet...:-) I think that EPNdB values can be deemed pretty reliable in establishing whether an aircraft cabin is a comfortable space or not..

I haven't been on a DHC-8 in a while, funnily enough likely to be tomorrow.

It never overly bothered me when the active cancellation was running - but maybe my memory is hazy. Will report back Sunday!

Oh, I was talking about the 'good old ones'. I'm hoping you'll be flying one with active cancellation technology!

Those GE90-115bs aren't no joke when they start up. I seen some videos and you can hear them across the field. In the cabin its vibrating the cabin very intense. A whole lot and far worse when a 737 starts its engines.

I totally concur that the 777 is by far the title holder of "noisiest current aircraft today" - and by a long margin. It must be the mighty engines! I try to avoid them as much as possible, but sometimes that is not possible. I have flown in Y quite often in ME3 airlines, and had a few fortunate upgrades to Business (at the front), and there is a bit of a noise difference (helped obviously by the "different" service!)

I wonder what the B777X will be like - Boeing is widening the pax space by 6 inches (from memory) - in other words, the walls and their padding/insulation are being seriously reduced. I wonder what the end result will sound like!!

It makes me wary of this impending new 777X, when I am mostly looking for A380-levels of noise (the quietest) on my LH journeys these days

Yes, start-up is impressive, to say the very least! I love it though! The reverberating vibrations of a GE90 starting up are pretty intense...

I am told by far more technical-savvy people that the 777 'noise issue' stems not only from the powerful engines, but more so by a combination of 1) reduced insulation of the sandwich paneling, 2) the aircon units/packs + PSUs, 3) aerodynamic noise.

agree that a380 is the most silent I've flown (didn't try though the 787 and 350) the a340 (lh) was the coldest cabin... maybe they wanted to save on heating... among the single aisles 320 from AY the most silent (could hear only zzzz from the engines) b737 far more noisy. still didn't try the neos/maxes

I just came back in trip where I flew an A343, B77W, B772 and a A333. I found cabin noise to be similar across them. On the startup the 777 takes the cake but I also enjoy it for some reason. But at cruise it’s just like any other airplane to me. The quietest of the bunch would have to be the A343 but not by a very large margin.

You will definitely 'feel' (the deep vibrations, that is!) and hear the distinct growl of the GE90 on start-up, and when spooling up. The RR Trent conversely has an amazing high-pitched whine when spooling up...love that too! Enjoy your flights mate! :-)

GE90-115Bs make the entire terminal vibrate during start up! They are no joke!

On the UA 777-222s with the PW 4000 series engines, the startup vibration is very loud as well. Also, in certain seats near the middle, when the engines are idling it makes this very uncomfortable vibration almost like when you have certain configurations of windows opened in the car. We landed in OGG and had to wait 25 mins for a gate while idling. I thought I was going to lose my mind

A380 beats all I have tried (never flew A350, though). usually sit over wing and upon take off, you barely know there are engines. In flight not as quiet but still the quietest; first aircraft I have flown where noise actually drops a bit in some zones aft of the engines.

Hear hear. During the takeoff there is a phase after they retract the gears and before aerodynamic noise sets in that you need to look out of the window to know you are airborne and moving.

I can tell you that when the gear retracts, the 350 cockpit sounds like you're sitting in a construction site. The noise is quite spectacular. After that it is very quiet.

I'm one of the weird ones. I snore pretty loud so I like loud airplanes as to not piss off and annoy other passengers. I like to sit behind the wing where it is noisier.

Would you rather hear extremely loud snoring or somewhat loud engine noise?

That’s similar to the A380 which also has very noisy flaps. The 787 is similar, but it isn’t the flaps that are noisy as much as it is the hydraulic pumps that run during that operation. They are so loud in fact that you can just hear them over the engines at a decent distance away. Maybe it’s also just because these planes are all otherwise so quiet all this machinery seems even louder.

Well you will always hear loud engine noises, but only hear loud snoring when you are close to someone that snores and if the fall asleep. So do you want to have loud noises all the time or snoring only some of the time?

I don't think you really understand how loud I snore. Besides, I like jet noise. I hate these new quiet engines.

Who would enjoy watching the blue angels or thunderbirds if they sounded like a citation flying by?

That is nice of you to be concerned about me when we are ever on a plane together...lets see the chances of that is almost zero. I have a choice for my next flight of the 77W or a A332. I think I will take my chances with a lower cabin noise and take the A332 and not be subject to the, while still nice to hear, the roar of the 77W and then the very loud conversations to be heard with people right at the back of the aircraft.

IIRC, the A380 was too quiet that they had to add some ambient engine noise.

I find the 777 is best before and behind the wing. Over the wind there’s a fairly high pitched whining hydraulic noise that drives you mental unless you can mentally block it out.

Having said that, the A330 is almost boringly quiet in the sense that takeoff is almost a non-event, which as an a geek is a let down.

In terms of noise the A343 and A346 are completely different aircraft. The A343 is like sitting in a room with a lot of teenage girls drying their hair. On the A346 I was waiting for the engines to spool up at takeoff, but we just surged forward with little extra noise. A fabulously quiet and comfortable plane. It's been a few years since I flew on one but subjectively I liked it even more than the A380.

Conversly the 777 is an horrible passenger experience. It's noisy. While the view is good, if you have a window seat, because it flies so low, you get noticably more turbulance. It's very cramped at 10 across. I avoid if I can but it's so ubiquitous you're often stuck with them.

I don't mean to come across as anti Boeing, but if you look at all their current products from a 737 to a 748, and as they're normally configured in economy, you'd rather be on an equivalent Airbus. I can't think of a single exception.

Re: Cabin noise comparision A330 / B787 / B777

Also noise might vary between types due to:
- flight regime (takeoff/climb/cruise)
- which row on the plane
- how close/far from the window

And noise levels aren't the same as character of the sound, which can affect perception.
It's really hard to give anything other than a very general answer.

Hear hear. During the takeoff there is a phase after they retract the gears and before aerodynamic noise sets in that you need to look out of the window to know you are airborne and moving.


True. On one particular EK A380 flight, my friend fell asleep during a very lengthy night taxi... he woke up literally just after a very gentle and stable rotation and asked me how long still it would be before taking off...

In terms of noise the A343 and A346 are completely different aircraft. The A343 is like sitting in a room with a lot of teenage girls drying their hair. On the A346 I was waiting for the engines to spool up at takeoff, but we just surged forward with little extra noise. A fabulously quiet and comfortable plane. It's been a few years since I flew on one but subjectively I liked it even more than the A380.

Conversly the 777 is an horrible passenger experience. It's noisy. While the view is good, if you have a window seat, because it flies so low, you get noticably more turbulance. It's very cramped at 10 across. I avoid if I can but it's so ubiquitous you're often stuck with them.

The 777 flies in the same flight altitude regime as all other large jet powered passenger airplanes, about FL280 to FL410. The fact that the heavier -300ER on a 14hr flight may stay at FL280-320 for a bit longer than, say, an A380 or 787, has minimal impact on turbulence, the worst weather related of which is well below FL280. (Then again several of your points echo known a.net flashpoints (hairdryers... really...) so I don't know if that is trolling or not..) (They do look like hairdryers though)

I've never been much above FL35 in a 300ER. Never been much below that in an A380. I do notice more turbulence, and yes, earlier in flights, so I think my point stands.

I don't think the CFM's on an A343 look like hair dryers, and from a passenger experience it's not really relevant to this thread, so I don't know why you mention it. Most people with reasonably sensitive hearing would agree that they're a lot noisier than the engines on an A346, so I'm not sure why I should be accused of trolling.

Actually, seems like the person trolling may be you.

As an aside, and as a consumer and believer in the importance of people's health, I think it would be best if 777 was forced to be re-insulated. I certainly go out of my way to avoid it. It is a wonder that noise isn't considered by consumer / employee health protection agencies. There's been plenty of noise-related bans of aircraft over the years, it is time that the passengers and crew be considered in addition to people living under flight paths.

Sigh... I was joking. I apologise if you did not get the reference. I don't troll, I was just making an a.net insiders joke. Again, my apologies.

IIRC, the A380 was too quiet that they had to add some ambient engine noise.

No, they didn't.

I love picking up the good vibrations. It gives me the excitations.

It surely is considered for flight and cabin crew as that is their working environment. For pax it is only a comfort issue, nothing that any agency would care about.
