I was browsing youtube and I found a good video of an -900 taking off. The sound in the NGX are exactly the same!

 

PMDG is designed to be realistic. Nice video !

I'm still trying to figure out how to get rid of the annoying chainsaw sound during cruise...

Writing them off completely as someone suggests is not an option, as the other flight profiles (take off and climb) sound a bit tasteless. I'm wondering maybe playing with the sound levels in sound.cfg will do?...

How come the FD Master lights are lit on both sides?

The grind of the engines when at full throttle? That's what they sound like. Probably the best sound there is in a plane.

Nice video,which only fortifies the respect I,and many others have for the PMDG rendition of the NG!

 

Cheers!

You learn something new every day:

 

From the PMDG NGX FCOMv2 Ch 4.20.4 (pp216).......

 

F/D modes are controlled directly from the respective FCC under certain conditions.

 

This independent F/D operation occurs when neither A/P is engaged in CMD, both F/D switches are ON and one of the following mode conditions exists:

 

• APP mode engaged with LOC and G/S captured

• GA mode engaged and below 400 feet RA

• TO mode engaged and below 400 feet RA.

 

Independent F/D operation is indicated by illumination of both MA lights.

 

When independent operation terminates, the MA light extinguishes on the slaved side.

 

Thats a pretty 'busy' phase of the flight.

independent operation terminates, the MA light extinguishes on the slaved side.

 

As you can see from the above, Take Off is an FD only mode and independent FD operation. If you notice in the video, the FO F/D MA light illuminates when the Capt. presses the TOGA switch on the throttle. Also notice that LNAV is engaged around 400 feet (SOP for engaging a roll mode, although HDG SEL is annunciated on this aircraft when TOGA is pushed) and about the same time the MA light on the FO side extinguishes.

 

Hope this makes it clear

That is what I had in mind.

Take off and climb (max thrust) can not go without them. Sound is a bit meager if you remove the chainsaw ...

Cruise is other story though. You don't really hear this "grind" in RL cruise. That's where I want to make it dispensary or at least sound less prominent..

Huh that's strange I don't hear it during cruise. Something wonky there for sure.

Actually this is quite a problem. The engine sounds are linked to the throttle movement so yes you get a fantastic sound belting down the rwy. However, in the RW as the a/c accelerates aerodynamic noise increases and the pressure wave pushes back the sound footprint of the compressor whine so it is not heard or barely audible. The only way to replicate that is to increase the volume of the wind noise to such a level that it hides the compressor whine (washing machine). So you end up with the sound of an open cockpit.

The only other way is a compromise between all the relevant sounds so that they mix well and don't create strange whooshes etc. What I've done in order to make the RR Conways on the VC10 correctly audible inside is to tail off the compressor noise at maximum. So one hears it on take off and on approach but barely at all in cruise.

I actually noticed that in the real 737-800 on my last jumpseat flight, during CRZ you can barely hear the buzz sound, you CAN hear the engines but not that constant buzz. Also, one difference is that during CRZ you have a deeper bass in the flight deck (wind and engines) than on FSX. (Or it's just my cheap sound setup which has not the bass of the real engines ).

 

All in all, PMDG has done a very good job with the sounds, they sound really accurate. Very very slight differences to what you hear on the real 737 though, but seriously, I don't think you can get any closer than this. I am very satisfied (and I am a REALISM JUNKIE so that has to mean something ).

 

Can't thank PMDG enough for making this great add on.

Here's the deal on this - the fan growl is normally masked and drowned out at cruise by the wind noise and it's suppressed to some degree by density differences in the environment vs. on the ground (less air for it to "bite" into etc). Unfortunately FSX maps sound to the engines on a 1:1 basis - you get 1 sound setting for every N1 value, that's it. To do it 100% realistically we'd need to be able to tell it not to play the growl sound (or reduce it pretty hugely) when certain conditions about the pressure and airspeed are true. We can't do that within the FSX sound framework unfortunately.

They should be - the NGX sounds were recorded on the real airplane.

Ryan thanks for the answer.. I've been living with that since the NGX came out and I don't have much complain anyway. My flights are usually in the range of 200-400NM, and the cruise phase is not that long. Other story would be with the T7. I hope sound model of the GE90 would be more "cruise appropriate".. Cheers!

Similar to what I said. The only sound file to which volume is linked to airspeed is the wind noise. The sound.cfg works fantastically for props as there is always the prop noise (of which the best of the best has to be four RR Merlins for the Lancaster bomber!) but for jets that crucial transition to cruise can't be modelled. So either you choose a great take-off sound or an authentic cruise sound. To get a compromise between the two is really quite difficult. It's taken me two whole weeks of fiddling a bit here a bit there to get an acceptable rwy acceleration noise and compressor whine on approach. The other thing to note is that rarely when processed by the sim sound engine, do the original beautiful sounds recordings sound the same. In order for my original sounds to "sound" real they have been heavily doctored by various sound programmes.
