[INVESTIGATING] Strange Harrier idle sound on parking with 0 wind... o_o


Recommended Posts

Why would the engine make sounds as if strong wind-turbulences are causing sound-waves to change directions? (or what else is happening here that we hear this? What is the source for this sound, a real Harrier pilot?)

fixed, added video to demonstrate.

What are you even  trying to show here?   You are basically moving your head back ad forth quickly. 

Yes, I tried to indicate that the audio-spectrum is wildly fluctuating with this new harrier engine sound, sorry.

Are you talking about the human capability to hear the audio source direction when turning head? Or something else?

As the engine is behind our backside, so turning your head to right will increase the volume on right side and lower at the left side etc.

 

But....

 

How should it really sound in Harrier considering you have likely a earplugs and helmet, and then you are a inside closed cockpit, where you should be fairly incapable hear any cockpit buttons and switches sounds (that are there to mimic the lack of of tactile feedback operating those).

 

But what I do know from older aircraft, like MiG-21Bis, you can barely even hear the helmet radio as the engine is so loud and when you put Afterburner On, you can't hear the radio even.

Compared it to Hornet, it is far more silent as the engines are far, far behind you and air intakes are far behind you as well at below the wings etc.

But even there you should have challenges to hear the radio as the cockpit is not silent.

How it is in the Harrier? The huge air breathing Pegasus beast is just behind your seat, the air intakes are right behind your cockpit sides....

 

Basically just estimating, I think the audio stereo separation is too big in Harrier currently, that when you turn head you will hear way too loudly the right side and left side separately, while you should have far less the audio separation and so on just hear somewhat differently when turning head but not at all so major difference that you don't hear almost anything when one ear is toward nose.

 

So I think it should be fairly subtle difference as after all there is almost only the chair and some plating between you and audio source. And the cockpit likely should balance the noise a lot for monotonic.

about the fluctuating noise only!!

Ah true, so is there a way currently of disabling all cockpit-switches-sounds? 🙂

Source please (about this in mig21)

Negative, in Hornet, it apparently is the generator which causes that crazy-annoying continuous non-fluctuating sound (according to some users. I never ever saw an official ED statement about that Hornet cockpit-sound iirc.....)

doesn't matter if there is 0 wind on the server... the air would be streaming into the engine in a laminar flow afaik... And one could wonder whether Razbam tries to make such sound just more dynamic to make it more "interesting" to potential customers, instead of making it as realistic as possible 🤔 for example there is not any such fluctuation audible here: https://youtu.be/cTZUFKCmkAs?t=19

Yeah Im lost as to what the problem you seem to think is. Perhaps you could explain this better

Know and use all the capabilities in your airplane. If you don't, sooner or later, some guy who does use them all will kick your ass.

Ok. Please ask your SMEs (real Harrier technicians/Pegasus-engine-engineers and pilots please, if possible) if even at 0 wind+0 turbulence (which the real pilots maybe never flew in?) if such engine-oscillations would even occur (at 0 wind+0 turbulence) and then if they would also be audible in the cockpit. To my physics-knowledge (and real-life experience of acoustics of laminar air-flow), it would not occur (and thus not be audible) if the weather in the DCS mission is set to 0 wind and 0 turbulence.

Perhaps my hearing is not as good as it once was, but where are you hearing this "wind" noise? If I hop in a mission with no wind on the ground at idle where should I be hearing it?

The engine tone is fluctuating in volume the entire time, which I would assume would be caused by wind/turbulences. I sent you an audio-file via discord of what exacly I meant.

Anyone else hear anything weird? I dont personally. The video has been given to the team to have a look. You are moving your head to which can change what you hear.

aaah okay yes, please also add a note to the team to only focus on the first and last view seconds of the video then, where I don't move. Thank you.

 

And did you inform the team that in that mission, there is 0 wind and 0 turbulence in the server?

Yeah, this fluctuating sound is driving me nuts. They actually integrated a mod that took the sound straight from an in-cockpit video, seemingly without any postprocessing. It sounds horrible, and I'm pretty convinced this fluctuation is a microphone artifact.

Ooooh okay 😒

How do you know where they took the sound from, in that mod?

Someone posted the video in question when I complained about it. If you look around the board, the thread should be somewhere in there. I think it was in the main AV-8B board.
