I have flown on an MD80 and MD90 before, and I didn't seem to think that the MD80 was loud at all. The only loud plane I have ever been on is the DC-9. And even the DC-9 was not that loud (Considering I was in Row 28) The only Super Quiet Plane that I have ever been on is the 717-200. That plane is so quiet, I sometimes wonder if the Engines are Running. But does anyone in here think that the MD80 is "Loud". IMHO, It is quiet, but not quiet enough for Stage IV from the ICAO. The 737NG, 767-300/400, 717, MD90, A320-232(Not 211) and the A380(Guess it has to be) are the only planes I know of that are Stage IV.

I've spent up to four hours flying in MD-80s, and for sure, the closer you are to the rear of the cabin, the louder it is. Of course, with tail-mounted engines, the noise level in the last few rows is much higher than at the front. Also, MD-80s and DC-9s tend to have alot of resonance in the airframe due to the engines, which are not of the latest design.
If speaking about Stage III compliance, I discovered in a recent post that the MD-80 is indeed compliant. However, I live near MKE, and when MD-80s take off, they ARE rather loud. It is definitely possible to tell the difference between an MD-80 and a 757 or A320 in terms of noise - the latter two are much quieter.

I witnissed a landing of one today at schiphol, an alitalia one from a very smal distance, and I thought the landing was VERY quiet. Comparable to that of an RJ100 for instance. I dont know about the takoffs

I took MD 80 twice in the past few days flying from CDG to Bologna on Alitalia. On the way over I got upgraded to business and i was impressed by how quiet the ride was. On the way back, well back in the back part of the airplane...and it was a bit noisy, but not excessively either.
The plane back was City of Caliagri reg number i-dawb. we landed 20 minutes early. Going over to Bologna was i-datd, and what a great ride that was...maybe because i was in business class. At bologna there is no jetway and it was excellent getting off the aircraft using the stairway. In CDG we it was the bus that plucked us from the terminal and fed us to the aircraft directly. Alitalia staff was very nice though the food was just like any other airline food.

JHooper, Did you know that on Row 31 of Airtran's 717s there is no window whatsoever, and the seats do not recline. Imagine asking for a window seat and they give you 31A or 31F and you don't get a window or recliner. Oy... That would be a ripoff. But believe it or not, some people have to get that seat, and some people would rather trade in their ticket for one on the next flight. But the Pro of this situation is THE BR715 ENGINE IS VERY QUIET EVEN IN THE BACK. So they might just listen to the beautiful hum of that Rolls-Royce and sleep a bit. Is it me or is it really true that the only thing about Pratts that sound good is that high-pitched whining sound. IMO, Nothing can compare to a good ole' Rolls-Royce Engine.

I do know however that the latter is bigger in Diameter and has only 1 fan instead of 2 fans. The JT8D-17 has 2 fans and the 217A has 1 Fan. Could this make a difference on the noise level. Also, What is the deal with those IGV Vanes that are in front of the fans (You know the things that do not turn at all in-flight). The MD-90, and 717 does not have those. Do the IGVs just have something to do with Old Fashioned Engines, or do they just prevent people from being sucked in. If that is the case, why do they not put them on any other HBPTF Engines (High Bypass TurboFan Engines) Especially the CFM56 on the 737.

The MD-80's are not quite when you see it takeoff. Every weekend we have Onur Air with their MD88 at Billund Airport and when it start rolling on thne runway it's very loud and later a rumble can be heard, almost sounding like thunder. That's what I like about the MD-80 engines.

The MD-80 series is a very comfortable and quiet aircraft. From the outside it is a bit different. As far as I know the P&W JTD8-217 have a low bypass ratio which makes them hardly Stage III compliable. Difficult thing for future noise regulations, anyway I hope they will stay for decades!!

MD80's are incredibly loud from the outside during takeoff, and landings (reverse thrust). I believe some have been outfitted with noise reduction devices (not sure though), but as an example, I was driving along Astoria Pkwy (or Grand Central Pkwy) right by LGA, still almost 300 feet from RWY4, and an MD80 had just applied full thrust, and the car was litetally shaking.

Having watched AA S80's take off at the end of Runway 1R at SFO, I can say they are quite loud planes when full power is applied on takeoff.
This is why I think AA maybe looking at a major re-engining program for their S80 fleet that could 1) make the planes comply the new ICAO Stage IV noise standards and 2) lower fuel burn. Right now, the only engine that fits the bill is an uprated version of the Rolls-Royce Deutschland BR715; that is not going to be a problem for AA since they are already a big user of Rolls-Royce engines.

when i go spotting, the MD-80's are very loud when landing and take off, but when i flew on one for AA or to be more accurate an EX TWA, i was seated at 7F and it was so quite during take off, but once it landed, the thrust reverse caused the engines to roar so loud.
