"speed sound"

[karras85]

hi...
there is a way to manage the volume of the wind at high speed...?
because sometimes the sound dont let me hear the cars engine... and that is not so real...

and with the fastest cars is worst...

thanks

Actually that's very real, have you ever driven at over 100mph, the wind noise can get very loud and easilly drown out the engine noise. The wind noise almost fully drowns out the engine noise on my 306 at certain speed, and I can tell you now, the engine isn't exactley quiet with it being a 1.9 model. Also deoending on if the engine is infront f or behind the occupants has an effect, if it's behind it'll be easer for the wind noises to drown the engine out.

 

[karras85]

the faster i drove was 160km/h on a 1.6 chevrolet corsa...
and dossent make so much noise... even with the windows open...

nah, it's entirely real as live4speed says.

The engine dBA could be cruedly defined as a function of the RPM for a given car (assuming air cleaner and mufflers/resonators, etc, are not changed) - the speed of the car does not affect engine noise levels. - note that revving the engine of a car in neutral makes it louder... but you still arent moving....

The aerodynamically generated wind noise, on the other hand, is going to increase as a function of your velocity (or maybe velocity^2 as is often the case in a lot of fluid mechanics equations) - and a great many other things related to the study of integral acoustics and the Navier-Stokes equations with CFD software ...advanced topics I know nothing about.... I think it's called computational aerocoustics...

either way, at some point the wind noise will become greater than the engine noise. When the perceived Sound Pressure Level of the wind noise is 10dBA greater than the engine noise, then for all intents and purposes, the engine noise has been totally drowned out.

Oh, and opening your windows defintiely will make a difference in real life. The pressure drop you can feel with your ears is indication that the flow nearby flow has become more turbulent - you have more buffetting, and as a result, more noise. Not only that, but the glass is no longer there to act as a sound barrier.

And, just like your situation, the game doesn't make very much wind noise at 160kph either.

I think the best way to manage is a) drive slower, or b) keep a shifty (bad pun, I'm sorry) eye on the tach while you drive.

 

[karras85]

lets put an example...
if you see f1 races... you will hear the car engine Sharp
but not the wind sound...
now...
hear a formula gran turismo at the most similar conditions... (the same track are exacly the same (monaco for example))
the engine sound is different than a real f1...
but the wind sound is very loud...

 

[Boundary Layer]

you're comparing apples and oranges here, if I understand you correctly.

The phenomena you realize has to do with octave band frequencies. If you're watching a live F1 race, from a car camera equipped with a mic, the mic is desgined with an octave band specifically to pickup the frequency of the engine sound [which viewers want], but not the local windnoise.

The drivers most definitely will hear the wind noise from where they're situated though - there's no way for them not to. This is what GT4 looks to replicate.


actually... you do occasioanlly hear wind noise in F1 broadcasts - I immediately think of some of the cameras/mics at Montreal or Melbourne that are situated trackside on barriers. The mic's occasioanlly pick up the pressure difference created in the air by the cars as they pass. (NASCAR has far more cameras like this - it might be a better example)

 

[karras85]

we start talkin abut how to change the volume and end it with a hard discussion...
the answer to my question is no...
untill i drive a race or fast car i cant say no more....

thanks anyway....

 

[Boundary Layer]

lol, ya, I took it a bit over the edge - there's no way to minimize one sound and amplify the other through game options. You're stuck with it as is.

 

[the Interceptor]

I remember a video with a good demonstration of wind noise. I'm searching for it at the moment ...

EDIT:
there you go: http://www.mymegabusa.com/Video/Megabusa Nurburgring.mpg

I'm afraid it's on the large side with 114 megs, but it's not only worth it for demonstrating wind noise, but also nice for motorsports and Norschleife-fans.

[karras85]

i love that track...
is the old school...
fangio, carachiola, ascari...
the silver arrows..
the auto union... (the car who makes the drivers be afraid...)

and abuot the sounds...
is a possibility to create a bug report to show this kind of details to "gt creators"????
or there is one and i have no idea about their existence....

The point of view is different too, if you mean from the spectator point of view, then go watch the replay from the outside and see if you hear noise. But if you are talking about when they put an in-car camera in a real f1 race, I'm not sure, but I think the microphone is somewhere inside the helmet, and if it isn't, its not in a place for wind to hit it. Also, in gt4 they are trying to recreate what you would acually hear while in the car, not a sound broadcast from the interior.

There is no way to change the volume of the sound.👍

 

[Mt. Lynx]

Allthough I must say that the engine sound in RUF´s are a tad on the low side. They do make a bit more noice than that toned down humming in GT4!

thanks Mr. Know-it-all.

 

[X-Othermic]

This was something i only noticed when i started admiring the game, grahpics wise. It's a good touch by PD.

 

[Niels]

Team66, yeah I sometimes cant control the RUF because I enter corners way too fast. It's because of the lack of sound I guess.

Honda2000-drift, you could as well just say Thanks and post some additional stuff regarding the subject, dont ya think? Because that was a useless reply.

 

[chinko]

The mic's occasioanlly pick up the pressure difference created in the air by the cars as they pass. (NASCAR has far more cameras like this - it might be a better example)

they have the camera's inches from the barrier, and because they pass so close and create that pocket of whatever around them the camera goes quiet as each car passes, not like slightly quieter, but basically silent

Maybe a surround-sound system would help? The noises should all be coming from the rear of the car, after all.

Useless, and rude.

nah, it was ok - I'd rather be accused of being a know-it-all than a know-nothing.

There are too many know-nothings in this world, anyway.

 

[FaLLeNAn9eL]

im one of them

 

[honda2000-DRIFT]

yea i wish we could all be like "boundary layer", know everything and lay boundaries... sounds like a council workers job description...

 

[Touring Mars]

honda2000-DRIFT, I don't know if you're fishing for a response or trying to start an argument, but unless you have something more constructive to say, I wouldn't bother if I were you. Please try to keep it constructive, relevant and civil...

Thanks,
TM

i mean...
steady camera...
but dosent matter... you cant change it...
so...
