What a REAL Merlin sounds like at Takeoff Power - from a aircraft perspective

[Venturi]

Note the sound changes depending on relative "line of sight" to the back of the exhaust stubs. You hear the sharp staccato of the exhaust pulses from the rear of the aircraft. While from the front, the subtle gear whine of the supercharger is heard while the exhaust sound is muted.

Nice but the recording quality is rather poor and isn't what you'd actually hear.

[69th_chuter]

And it's at no more than 55" boost (limited by today's Blue gas) and very probably less (a lot of operators use 45" or less for takeoff).

[BraveSirRobin]

The sound quality in that video is terrible.

[Yakdriver]

heresy.
thats not a Merlin.
That is some V-12 Hemi Mopar what-have-you Fake Sh(beep)
Are you out of your goddamned Mind?


Merlins were used on British stuff.
Everything else is Fake.

The P-51 used a merlin, though it was American built.

see.
MOPAR i tellyou.
It´s allBS i tellyou.
is american.
cannot be merlin, for merlin is BrRrRitischchch

Were you expecting studio sound mics mounted on a real P-51 as it takes off? ?

It’s exactly what you’d hear if you were in a pilot plane next to a real P-51.

The audio is distorted because of the recording quality, so it's not exactly what you'd hear. It's like when you watch most videos of firearms being fired, they don't actually sound like that in person.

Sorry, but even I can tell you can`t get a real idea of how the engine truly  sounds from that terrible audio quality.

[Venturi]

This video is a much better way to know what the sound of the aircraft is like in flight than a recording from a flyby, due to the Doppler effect. Additionally, you won’t get the correct sound by recording the aircraft at idle or even run up. The power setting at takeoff are way higher and this directly affects the sound. Knowledgeable people will understand what I mean. Thanks.

Only because the frequency range is clipped, usually because the bystander is standing where they shouldn’t be.

I understand what you mean but the recording quality is poor so you won't have high quality audio and it won't sound as it does in person. If you were to take high quality equipment and record the same thing it would sound much better and different.

[II/JG17_HerrMurf]

Don't care how good your equipment is, the engine sound is distored by the wind noise and even the rolling noise on the exterior. Most of what I'm interested in, for the most part, is the interior sounds anyway. That is where the "office" is for me.

Thank you for the video. This game has gone far in graphics and FM but regarding the sound no real progress was made in the industry as a whole. Actually a propper sound could add a whole new layer of immersion and could help to popularize the genre and boost sales.
Something like "the only game where the planes sound as the real thing", that may add customers for sure. And would spread tons of youtube videos.
In a world where they can make AI sound like real people (see google  presentation) I do not see why they cannot make a game engine sound like real engine.

I've heard, in reality, hundreds of Merlin engines in take-off and most other modes and that recording does not sound right.

 

(The joy of attending many Duxford and other airshows.) 

[Venturi]

The problem is that so many people conflate the ORIGINAL sound source, with the sounds they HEAR from the ground as aircraft approach, or from a distance, and then associate as being "the right sound".

 

The sounds that people hear are modified by 1. the Doppler Effect, 2. distance, and 3. sound shadowing. The way the plane sounds RIGHT NEXT to the plane, while travelling at the same speed as it, is very different.

 

Point 1: The Doppler Effect SHIFTS the entire frequency range UP or DOWN, depending on the approach of the sound source to the listener:

 

 

Point 2: Distance, it attenuates high frequency sounds while emphasizing low frequency ones: 

https://www.quora.com/Acoustics-Do-high-frequency-sounds-dissipate-less-in-air-than-low-frequency-sounds

 

Point 3: Sound Shadowing, the wings will attenuate engine sound, the exhaust flow direction attenuates exhaust sound forwards, etc:

https://en.wikipedia.org/wiki/Acoustic_shadow

 

For all these points - this is why the Original Video I posted, turns into this when on a flyby:

 

 

 

 

It doesn't mean that the airplane sounds like a flyby when you're flying next to one, or that it's what it sounds like from the cockpit. In particular, the American aircraft's engines sound very pathetic in game at the moment. I would like them to sound like the hot-rod engines they are, when you are right next to one.

Whatever nagging nuance, big or small, gamebreaking or not, accurate or not, Kornezov will find an appropriately dismissive/belittling [edited] post.

Sitting in the cockpit with a flight helmet on you just hear a very load noise.

A very loud ENGINE noise. That's what you hear in a racecar, too.

I don't believe it's supercharged.

They are. We've sheared the quill pin on the super on another one of the Allison boats - it blows the intake scoop off the boat

Here's a vid of a MkIX being run up on the ground with a decent mic and no wind noise. Also a good example of the exhaust flames

Only the Spit sounds somewhat better. The whole industry is not paying enough attention to this issue.

It really depends what you are looking for or more accurately listening for? When talking to a WWII P-51 pilot he said it was just a VERY loud noise from the engine so loud that he couldn't hear impacts to his aircraft when it took hits but he felt the vibrations. I know we are talking about personal anecdotes here but if you want the rolling/roaring tones of an engine and the doppler effect of a majestic Spit gliding past you at an airshow, you won't get that from inside a simulated aircraft.  I think the engine sounds from inside the cockpit are perfectly fine, although I know many may not agree with me.

 

Edit: I'm sure at some point a bright spark will produce a sound mod that will give you what you want?

The P-39 sounds awesome in this regard. The IL-2 not so much.

[LLv34_Flanker]

S!

 

 Could they at least make one thing. Engine sounds, no matter the plane, do not change at all with cockpit either closed or open. Same sound level either way.
