"What you are *cluelessly* referring to is the Doppler effect however, since once you reach your point within the aircraft the position of the source of the sound and the observer remains static therefore, the pitch and noise level also remain static for any given position within the aircraft. Secondly, are you really of the opinion that walking through the cabin at 2 or 3 mph causes a palpable change in the doppler effect that you can perceive? Unless you are a bat, I think you should quit now. (With that said, if you ARE a bat, then I truly apologize for my ignorance)."Static for each person compared to the engine, but not each person compared to each other"WOW!!!! Perfect example of the hole in the Ozone layer beginning to take its toll on humans."What a baseless comment, you claim it's crazy to think aircraft have sound proofing material?"I'm done now. Your signature is very reflective of whom you seem to be. Your education (or lack thereof) really does intefere with your learning. "Wow so now we go to insults when your childish tantrums of "WAAA I WANT WIND AND ENGINE NOISE WAAA" are not heard by anyone else

> I am pretty>sure companies install material in the cabin to drown out the>certain frequencies that are not installed in the cockpitYou are certainly making it up, if you are so sure better come up something more tangible because your conjecture flies in the face of logic and logistics of building an airliner. There is absolutely no reason that cockpit would be less protected from sound because companies would like to save a few $ on material and stop at row 1. Also number of 744 pilots confirmed that 747 has very quite cockpit and one doesn't evne have to wear headsets (capt. Alan Carter, Asiana). Michael J.

wow you children just can't give up. Nothing will make you happy. Instead of enjoying PMDG's airplane, you all run around trying to find everything wrong with it like it will earn you a medal or something... give it up. If you don't like the sound, turn down the slider settings and stop acting like such spoiled bratsAnd I have no doubts airliners would try to save as much money as possible, what world do you live in?

>wow you children just can't give up. Nothing will make you>happy. Don't switch subjects Alex when you loose your argument. The conversation was recently not about the PMDG product (which is 1-st class) but about your nonsensical uncorroborated statements about the sound and thermal proofing in airliners skin. This converaation could have been over long time ago. *:-*Michael J.

I know exactly what the solution is to this problem, I find that the takeoff sounds are perfect, right on the money. But I agree that during the climb, the wind should take over the engine sound, making the engines almost completely unaudible. We need a utility that will allow us to control JUST the engine sound during flight while flightsim is running and not from the menu. Make the sounds normal for takeoff, and gradually reduce them to almost nothing as you climb.Anyone know if such a utility exists?Alex CYUL

Shall we take up a collection so the combatants can fly on a real 747 and then check the sim sound on a laptop vs the real deal?

I don't have the PMDG Queen (yet!) but I recently flew 40 hours on a roundtrip to Asia in the upstairs cabin in a real life 747-400. There is no audible engine noise up there (or in the cockpit) at cruise, but there is a great deal of wind roar/rush. From previous experience jump-seating in the 744, in the cockpit it is a more hushed roar than in the pax cabin behind. It's a sort of rarified rushing sound. The only significant engine noise in the cockpit is on takeoff and climbout, and after landing with reversers. Once you get above FL100 and accelerate to climb speed for beyond, the wind noise increases substantially and the engine drone fades increasingly into the background. By FL200, there is mostly wind roar upstairs.In the coach cabin of the 744, there is more audible background engine noise and rather less wind noise than upstairs.I would not be inclined to swap the 744 sounds for the LDS 767 (which I do have) sounds because this would not be realistic.There are two sound folks who've done yeoman work on the engine sounds of the heavies (including the 747 series) and whose files are available at AVSIM. One is Devyn Silverstein and the other is Mike Maarse. I have "mixed and matched" some of their sound files and now the sounds for many of my non-PMDG 747-400 aircraft (POSKY and Meljet) are highly realistic, including wind noise.An alternative is the sounds from the original PSS 747-400 if you still have them. They were excellent (especially the Rolls Royce RB211 sounds--they sang like no other fans!) and I use them on several of my 744s.JS

Hi JSACKS,Can you post a list of scavenged sounds that you've mixed and matched.I too am a fan of Des Braban's and Mike Maarse's sounds. Hope they're working on a PMDG744 set. The PMDG 737 replacement set was simply awesome. Also, I'm very displeased with the co-pilot sounds which are just borrowed over from 737NG, and weren't any good to start with. What I miss in PMDG's sound set are the lower harmonics necessary to recreate all the rumbles of a heavy. The soundset is too "tinny". External sounds are very weak. How is it that LDS767 can make their engine sounds fade on climbout but not PMDG? Has it got something to do with sound.cfg and values contained therein?Keith
