engine sound at altitude

Featured Replies

Hello! No problem here just a question on what others think about the engine sound during cruise. I think the takeoff and climb sound are great. The grrrrrrr of the fan is very close to the real world sound. However i notice I get the same grrrr sound at fl370 with N1 around 88 percent. I was once told that you dont get the grrrrr sound at higher altitudes due to the less dense air. And from my experince in the jumpseat its almost all wind noise during cruise. Is there a way to decrease engine sound above a certain altitude but keep it as is for takeoff and climb?

Good question, I've noticed this as well.

I have noticed this too. In FSX you can decrease the engine sound slider. Its not the best solution but it does improve it.

I'm my opinion it would be great that the wind sound would be hearable at a higher speed. Then, if you decrease the engine sounds when you are at a speed, for example, below of 200kias, you will hear the engines. But if you are above 200 Kias, the wind sound will make that engines are not so loud so the sound experience can be greater in cruise.Does someone knows how can I modify the sound.cfg so that wind sound below a speed to be weaker?

On my system the winds will become more silent already when I'm reducing speed. It all works just the way you're discribing it.

Not the easiest way and you might have to consult the SDK for it, this is how i would do it:First find the Wav that produces the GRRRR sound.Then search it in the sound.cfg (more than one, at least left/right engine)In the vparams section, from the 0.9 mark and below devide all volume instances by 2.smile.png not easy..... backup first

Yes, exactly, I have the same experience. PMDG should re-think this sound issue, because this roaring sound doesn't come on cruising flight level.Can u recommend this for PMDG? This would be nice...Gabor

You should report to the Sound Engineer.

Yes, that is... But I think that wind shouldn't be perceptible at least until 190 knots. That's what I would change. I have realised that when you are rolling along the runway you can begin to hear the wind sound, what is not realistic for me.

Sure that you don't hear it in reality? In real world I'm flying gliders (Yeah I know that a LS4 isn't a 737 ;D) and there you can hear the wind very lound when you're flying at 190km/h (not even knots).It is even by far louder than the engines when you sit next to them in the pax cabin. So why not in the cockpit too?

Agree.And I guess most of us do, right? Myself being a sound geek Love.gif Wind noise is basicly all you hear in an airliner over certain speeds, especially during cruise. I've experienced this from jumpseats in various 737s, 757s and I might add; from the righthand seat of the Beechcraft 200. Some flightsim add-ons from the past actually got that part right. (but indeed lacked the endless stream of marvellous and realistic features the PMDG NGX offers, including a very detailed and spot-on soundset) If my memory serves me right, the Maddog2006 had the "right feel" soundwise at cruise speeds. And there was no trick to it - the wind noise just escalated as the knots rised. I guess one can adjust this in the sound.cfg of any MS aircraft. But the engine levels will still be there giving that GRRR an audible level. And the NGX does sound right when you e.g. leave cruise and decrease thrust, you should hear the engine rpm dropping giving a low rumble downward pitch, especially if you have a subwoofer connected.regards

My mistake because I didn't remember that when I was trying sound configurations I reduced engines sound. That's why wind sound is a bit loud at low speeds for me. When I'm on approach I can barely hear the engines, but if I raise engines sound level on FSX then when on cruise I will hear engines a bit loud. That's why I want to reduce wind sound level at lower speeds, but don't want to supress it!

I too think that the soundset is pretty spot-on except for hearing the buzz saw noise at cruise. This is unfortunately a limitation of FSX. The volume of wind in FSX increases in proportion to indicated airspeed, which drops as you get up into the upper flight levels. So basically, the max wind volume can't be set at any higher than 250 knots or so, because the sound would actually get softer as you climb and your indicated airspeed drops. I wish wind volume was tied to mach number instead, that would solve that problem. The other problem is that there is no way to set any sound's trigger or volume according to altitude, so there is no way within fsx to get rid of the buzz saw sound as you climb. The only way this could be fixed is if the sound simulation was totally taken away from fsx and just run through the NGX gauge like some other things are in the simulation.Ben

Yes, it is an unfortunate fact that jet sounds in fsx are never going to be totally realistic for all stages of flight withouth doing something to control them externally. Turbofans sound completely different at altitude than when operating at sub 10000ft. Up at a typical cruise level for example all you hear is a very deep rumble from the combustors, even at high engine speeds. The buzz saw only comes along when the tips of the fan blades reach the speed of sound relative to the air density, which in normal circumstances only happens in the dense air below 10000ft. Same for thrust roar, this deminishes as the aircraft increases speed and the shear effect caused by the differential in exhaust and normal air flow is reduced. So really the same engine will sound unrecognisable up at FL350 compared to on the ground. To get these kind of effects the sound engine would have to be bypassed or rewritten completely. Mind you, if anyone could do it it would be PMDG!
