Wow. There really are some pig-headed supporters of PMDG out there (mainly two that keep showing up in here). I also have those 777 digital sounds and the first time I fired up the PMDG I thought, what? These sounds are what I have in the 777 file. Aaron used the same sound files for some of the 737 sounds. The startup sounds are identical. I don't care what you people say, they are the same. I went out and bought the Ariane sound package and it is far better then the sounds that PMDG came out with, read....more realistic. I just hope that PMDG produces realistic sounds for the 747 instead of using 1 year+ old sound files made for a another aircraft originally.And Randy, really! I mean PMDG could have piston engine sounds for the 737 and you would fall on your sword defending them that they were realistic 737 sounds. Give it a break..they are not gonna kick you off the beta team.

The proof is in the videos. The proof is in the IRREVOCABLE fact that ALL turbofan engines whether be it PW2043, GE CF6-80c2, RB 211-535 CFM56-7 or any other exhibit the whining or screaming noise/ growling/roar that I keep on mentioning. I call this fact IRREVOCABLE bcause no matter how we might try to run from it, it come back to bite us in the #$$. Even bfore I typed this response I talked to one of my maintenance professors over here at the college and not only did he confirm it, he explained it. Firstly if u turn on your simple house fan u WILL hear a growling/buzzing and deep/low frequency hum type of roar(for lack of a better words). On top of that, the bigger the fan the more pronounced these sounds are. My church had these large metal fans bfore thet got their new AC system and these things used to be annoying due to the buzzing/growling(again for lack of better terms) type sound that it made. Try it at home. Y are flies so annoyin? Is it bcause they keep on flying and resting on our comp screens, not only. lol isnt it because of the buzzing sound that there wings make.? What about bees dont they sound similar in the fact that their wings also make a buzzing sound, even with a different pair of wings? or even worse a humming bird. Y is this.? My professor explained that the same thing with our house fans, bees, and all these winged creatures is the same thing that is happening with our aircaft turbofan engine. In fact did u know that the compressors in the engine can stall just like an aircraft wing. They call it compressor stalls- cause by air not hitting the blades at the designed angle of attack. Therefore u get one or more series of loud BANGs followed by yawing movements of the aircraft as the air flows through the engine in the opposite direction. Check it out, smartcockpit.com or sumthing like that. A turbofan engine is divided into four main sections(u guys know this im sure) Intake sect, compressor section, cumbustion chamber and the exhaust. The difference between a turbofan engine and a regular turbine powered engine is the fact that it had a large fan at the front that is larger than the rest of the compressor section. And that it provides higher BYPASS air. This bypass air moves over( but within the engine itself) the compressor, cumbustion, and exhaust sections of the engine. And provides added thrust to the exhaust gasses coming from the exhaust. (Read up on this for yourselves there is so much more to this.) At the back of the Compressor/cumbustion/exhaust portion of the engine there are turbines that are turning the compressors of the engine. These turbine turn or spin due to the hot air/gases that are escaping the exhaust. It is safe to say that ALL turbofan engines are made in this manner with minor differences of course. My professor reiterated to me that these whining/screaming sounds is generated from hot air and the hot fuel air mixture rushing at high speed through the Compressor/cumbustion/exhaust sections of the engine. Now check this out, I dont know if u guys have seen the pipes of a pipe organ. But there are several different sizes of pipes that it uses to create sound. Ill just mention a few of them: u have the 8 foot pipes, 16 pipes, and the 32 foot pipes. The difference bet thes is as follows.Irrevocable truth # umteenth: The larger the pipe in lenght, the deeper or lower in pitch the sound. In another instance, Take a rubberband and pluck it, the longer u stretch the rubberband the lower in pitch the sound will be. So we have our turbofan engine, in the Compressor/cumbustion/exhaust sections of the engine their are some compressor fans that are being turned by these hot gases. Their main purpose is to compress or shrink the air to something to the tune of 1/15 of its original volume. Therefore from the location of that large/main compressor fan(the one that is larger than the rest) the sizes of the blades are decreasing. So, guess what? The same way the air moving through the small pipe organ pipe is higher in pitch than the larger pipe organ pipe is the same way the hot air moving thru 15 sets of 2 fan blades- fifteen stages of compression each decreasing in size are going to be higher in pitch than the preceding. Therefore the sound overall is going to be that of a whine/screem( whichever u want to call it. There is so much more to this that my fingers will fall off and my choir director will faint if i tell her that I cant play on saturday.My professor also told me( for sum reason which I cant remember) that the larder the engine the less of those whines youll hear. I want to stop here and ask this - even though Iv moved on from this issue - where is the whining/screaming sounds in the INTERNAL part pmdg soundset- as heard in the cocpit/cabin videos and as explained?Gideon

lol. You're cute :)Anyways, I've been toying with the sounds and made 3 different demo sets:T/OSet 1 http://www.iseeinyouthesamefearthatwouldta...37/set2/t-o.mp3Set 2 http://www.iseeinyouthesamefearthatwouldta...37/set3/t-o.mp3Set 3 http://www.iseeinyouthesamefearthatwouldta...37/set4/t-o.mp3The above sets feature different eng/wind noises. Set 1 has more whine; set 2 and 3 are -nearly- identical, but with different stage 4 whine and different wind noise.LandingSet 1 http://www.iseeinyouthesamefearthatwouldta...37/set2/lnd.mp3Set 2 http://www.iseeinyouthesamefearthatwouldta...37/set3/lnd.mp3All above files feature new ground roll (more shakes and bumps), thrust reversers (louder with some delay), gear up/down (more wind noises), dampened GPWS callouts, and new FMC alert (no background statics).Here's another demo. I don't remember where it's from, but it's a sound of an RTO at 100kt with reversers http://www.iseeinyouthesamefearthatwouldta...37/737_demo.mp3Now be warned: I've listened to these with 3 different speaker setups and all 3 produced different unique results! So, take it for what they worth. What you hear also depends on how you setup your levels in FS. For the above I used 13-48% eng and 80-100% environment.I'm not sure if these improve over the original though, since I've already forgot what the original sounds like!

pig-headed supporters of PMDG You need to take a step back from the compter and take the wife out to dinner or the dog for a walk when you feel the need to become a @#@ just because people are having a chat about their opinions about SOUND. Don't like other people's opinions? Here is the [h2]suggestion box[/h2], maybe you can ask PMDG to only post what you believe to be accurate.. Best Wishes,[h4]Randy J. Smith[/h4]http://www.rawbw.com/~bdoolin/shinault/southparkcartmad.gif[h3]I WANT MY 747![/h3]Caution! Not a real pilot, but do play one on TV ;-)

ahahahaha... cartman!

There have been a number of threads on this issue over the past year and they all produce some passionate opinions. For what it is worth to my ears the PMDG sounds are spot on at cruise levels but miss the mark at other flight stages. But then the only FS aircraft with sounds that are indistinguishable from reality is the Fanda Dash 8 IMHO.Bruce

Hello again guys, U wanted proof to these whining/screaming/ growling/ roar noises that i keep on mentioning, well if the above brief explanation doesnt do it for u then check out what GE had to say about this and the innovations they are tryin to incorporate in their engine designs to minimize them. Taken from the ge website:"GE Instrumental in Historic Aircraft Noise Reduction Milestone August 23, 1999 -- EVENDALE, OHIO - Federal requirements state that all civil aircraft must meet quieter "Stage 3" noise regulations by January 1, 2000. Stage 3 aircraft are roughly five times quieter than Stage 2 aircraft.While jet engine noise is very complex, with different sounds radiating from different parts of the engine, GE Aircraft Engines has minimized the actual creation of engine noise, as well as muffling the remaining sound, paying particular attention to the most annoying characteristics of sound that humans find most objectionable.The big fan at the front of modern engines tends to create the two sounds humans find most irritating: the deeper-toned, buzz-saw noises, and the high-pitched whine. The compressor and turbine, and the process of burning fuel, also contribute to the sound. The exhaust makes the most noise of all, especially at full power, as compressed, high-speed gases shear through the surrounding air."Once again I admonish every enthusiastic simmer out there to study up on this stuff it is quite interesting when u think of it. At first I never liked the turbofan characteristics of engines in general. When I dloaded or bought soundsets I always used to change that " buzz-saw noise" to something more of a roar based on what I heard traveling in the cabin on the 757, 767, l1011,md80s, and 738s. But after studying up on this stuff I forced myself to accept it. And here i am doin the same thing with the pmdg soundset - dont like it but tryin to accept it (and find a better sound of course.) Im actually on 'who cares' mode now when it comes to their sounds. Im only going this extra mile to show what could be added to make the soulds closer to the real thing.So here we are: science explains it(even though science cannot explain everything); my professors confirm it; it can be heard in the videos pointed out above; u can hear it at your local airport, GE admits it - what more do we need.To find the above article go to ge website and type in the word whine or just plug this into your browser. http://www.geae.com/aboutgeae/presscenter/...r_19990823.html

Got the Arianne sounds in and they are very convincing. Even has "Jet Whine".

Did you buy the plane, or are the sounds available separately?BR,Frank

>Did you buy the plane, or are the sounds available>separately?>BR,>FrankYes Frank, I did buy separately. See this page:http://www.woodlandworld.com/Ariane/dept.asp?dept_id=1222

I agree with crvm!This thread is a bit worrying....u lot...they are only sounds on a computer program !!!!Go play some GTA San Andreas if u wanna vent :)You can fly a Cessna in that too hee hee

We are paying customers and we have the right to complain about this product ;)

>We are paying customers and we have the right to complain>about this product ;)I agree, and Im not disputing that at all :) This thread is just funny cuz everyones flapping over airplane sounds comin' outta computer speakers http://instagiber.net/smiliesdotcom/contri...y/corkysm20.gifIts funny & entertaining to read though...hee hee hee

Thanks!They must be VERY impressive to be worth 18 Euro!!BR,Frank

I have been retired now for quite a few years but spent 33 years in the aircraft industry as a test engineer in flight test. As my reduced hearing will attest to, I spent much time on the flight line around engines at all levels of power.I do not know how anyone can accurately assume the engine sounds in PMDG are accurate or not by having flown on a particular 737NG. First of all, GE produces 6 different models of the CFM56-7B engine for the 737NG series. They are the 7B18, 20, 22, 24, 26 and 27 and vary in thrust capability from 19,500 lbs to 27,000 lbs. This thrust differential alone will cause different sound levels and how do you know which engine is installed on the pariticular aircraft you are on. Where you sit in the aircraft will have a great effect because of the blocking effect of the wing, the number of passengers, the number of seats etc. All of these either deflect the noise, as in the case of the wing, or absorb noise in the case of passengers, seats and the basic aircraft insulation. If you are forward enough to be able to see the front of the engine then a certain amount of fan noise will be available. Add to all of this the wind noise over the fuselage, which is purely dependent on airspeed, and everything changes. Don't forget the air conditioning noise. If you happen to be near one of the risers from the ac packs this can add additional noise. As mentioned in previous posts weather conditions such as temp, rain, and altitude have a big effect.As engines get bigger they are getting quiter. This has been dramatically shown with the 777. While they are in the thrust range of 98,000 to 93,700 lbs they are much quieter. It should be noted that rpm of the GE 90-94B engine is in the range of 2552 rpm max at t.o. while the 737NG engine is approx 5600 rpm. This is a result of the fan diameter being 61" on the 737 as opposed to 134" on the 777. This reduced rpm, required to keep the tip speeds subsonic, results in much less whine and more of a low frequency buzz. The other big effect is the very large quantity of bypass air created by the outside of the engine and past the exhaust. This all has a quieting effect. Add to all of this the great advances in sound absorbing techniques designed into the engine inlets and the cowling and we have quieter engines.Getting back to whether the sounds that PMDG has created how do we know which engine they modeled and what was the status of the interior of the aircraft. Certainly we don't expect them to model all conditions possible. Personnaly I think we are getting down to the point of trying to "pick the fly specks out of the pepper". I am just happy to have a great airplane to fly. My thoughts any way.Tom
