Modern Airliners Too Quiet?

I recently flew on an Air France Airbus A380 to Paris and, for the first time in my flying life, I was awakened (twice) by other passengers who were snoring. Normally, such noises are drowned out by the din/drone of the engines. I also made a video of the landing in Paris and noticed the "extreme" quiet in the cabin (especially noticeable during cabin announcements and the firm landing). Additionally, I saw the A350 flying at the Paris Air Show and noticed how quiet it was. In fact the show announcer called it the "Hushliner". I am assuming that it will be even quieter than the A380 and that makes me wonder, might modern airliners be getting too quiet for those who ride inside them?

I think its fantastic that airplanes are now getting quieter thanks to better engine technology. Will certainly enable a better sleep but yes it also means hearing others snoring which is a downside!

A more quiet engine also enables more enjoyment while flying as your better able to hear the PTV if your not using noise cancelling headphones

They are getting quieter to the extent that surrounding ground traffic now sounds very noisy...

Bound to be louder in service once it has a full load. It has two less engines than the A380 so will be quieter.

Not a good comparison. A high wall deflects most sound from passing cars, while an airplane passing a few hundred or thousand feet over your head cannot be protected against.

CHAT OPERATOR

I read an article years ago about a research project by Boeing on cabin noise. I recall that they stated that with noise cancelling technology they could pretty much drown out all static engine noise in the cabin. But test results showed that passengers on long haul flights got extremely irritated by the mindless chatter and sounds their fellow passengers caused! I think it said that 50DB of cabin engine noise was considered to be a minimum or something.

I live in Auburn just south of SEA and a little further south of BFI. Take what I'm about to say with a grain of salt because I am in NO way complaining.......................

When A/C are departing to the south, you can totally tell the difference between say a 320/737 and a MD80. However when the flight path reserves, when I look up and see A/C landing to the north, you can barely tell the difference in any A/C. Except for the BA 744, for some reason they love to announce in a loud way that they are here!!!

Take an SPL meter along on a few flights. At cruise, total noise levels will be way, way above 50dB, at least on every commercial aircraft I have flown, irrespective of where seated. There's a lot of room for improvement down to that alleged noise floor of 50dB.

You seem to forget that living near an airport posses serious health risks that are not factors when you leave near cars and trains.

I live in Queen Anne, very close to the canal. I think we are under some approach paths.. in any case, it is very easy to spot planes based on sound--but only if you're really trying. I haven't heard of any noise complaints!

The modern 77W is not too quiet, it is still too noisy and cramped. This month did AF380 and KL77W on trip to Europe. KL crew was better, but their 77W in economy sucks. AF crews were poor, but they have a nice aeroplane. Note to AF/KL, give KLM the 380's!!

I have yet to fly on a 748 or 787, but also believe they will be more like the 380.

They are so quiet, I'm fearful one may sneak up behind me on the street and run me over the way a Prius does  

I rode in the upper deck of an A380 and absolutely loved the quiet. Has to be better working conditions for flight crew as well.

Random thought. Do in flight crew suffer from such things as tinnitis the way factory workers or others exposed to loud sounds often do?

That's weird, I always thought the MD80/DC9 aircraft were known for being extremely quiet in front of the wings. There is wind noise, but besides that you don't hear the engines at all for the most part.

I don't want to get into yet another Boeing vs Airbus but based on my personal experience, the air-con noise on Boeing, even the latest B777-300ER seems to be more noisier than AIRBUS A340 or A330. Even on A320 vs B737, I can hear the difference in noise. I am pretty certain it is related to the air-con. Perhaps, at cruising mode, the all speed circulation mode of Boeing aircraft tend to be have more noise than the Airbus make. I don't know why, but I can feel that.

On A330/340 and A380 the air conditioning is virtually inaudible during cruise (except at a few spots in the cabin). On A320 family it is not quite like that, the air conditioning has a contribution to cabin noise. What you hear in the cabin, which might sound like air conditioning, is actually the boundary layer noise (outside air flowing along the fuselage skin). That is by far the dominant noise source, while engine noise only contributes in the back of the cabin during cruise (not so during climb, obviously).

I do like the sound of a BR715 starting/running on a 717. I don't know what it is about that engine, but it has some GREAT sounds to it. It definitely won't be classified in my book as a "boring" engine. It may not be extremely loud like it's the JT8D on its DC-9 cousin, but it is, in its own right, a superb engine. That and the RB211-22B engine.
