do different car have different wind noise loudness ? like:
louder in rally car
loudest in F1
unheard in racecar (engine noise too loud)
silent in aston martin

Yes, the noise created by the car passing through the air depends on the aerodynamic properties of the car.

i tried the the "Honda Odyssey Mission Hall races"
is the same thing... to hear nothing to hear all...

In that case I must tell off my naughty, naughty, 1000W monitor speakers, for playing a sound which isn't there...

...I would expect the quality of your monitor loudspeakers is allowing you to hear the difference:tup: compared to say, those of a TV set. I know its surprising when I route GT4 thru my Home cinema system the difference in sound quality is very noticeable...although ultimately limited to the PS2's capabilities.

@karras85

While I more than admire your desire to push PD to make the most realistic sim they can with the GT series, I would personally rather see them work more on moving the actual vehicle physics engine forwar before putting more work into the wind noise.

That said, I would agree with Famine that through a good sound set-up the wind noise does not just 'stop' as you pop out from behind another car, unless you do so suddenly.

In the vast majority of race cars, at speed wind noise would be the dominant sound, and in some cars at lower speed teh transmission noise may well also drown out the engine sounds. Straight cut gearboxes are very, very noise things.

Its a sad fact, but a lot of race cars sound much better from the outside than they do from the inside.

Famine - have you been spoiling your speakers. One hour of white noise and make them stand in the corner facing the wall. That should make them behave in future.

I would agree that the PS2's weak area is without a doubt the sound quality, some of the engine sounds in GT4 are poor to say the least (and some are great), but I would agree that a good sound set-up does make a big difference (even if it does mean your wife moans that she has to go to sleep everynight to the sound of engines).

I'm playing a lot more GTA:VC than GT4 currently... You should hear the words my other half comes out with when woken at 3am by a six-star marathon...
 
ok... i will try more races to see if the change is brutal or not brutal...
depending of the race....

i suppose the f1 car dont making too much sound cuz the air resistance is almost nothing... only the front wheels make a red resistance... to scale from blue to red...
i saw it yesterday with the practice of f1 of malasia...

im going to figure out that...
different cars at the same speed makes the sound with the same volume...

separated from this... but is about the wind so i decide to ask it here

when you going for exaplme with the toyota 88c-v at 375km/h in sarthe II
if you get close (very close) to the barriers.. your speed slow down...
why this happend?
 
There's dust on the track off to the sides - you can see it kick up off the car (if you're in 'Copter Cam... See? It has its uses... :D ). This reduces traction which reduces your speed.
 
The slowing down is because there is sand near the barriers, you see the cloud of dust if you look back when driving there.

Of course it could be caused by aerodynamic drag too, when a car is really close to a wall the air between them causes the car to slow down a bit. But in this case, the reason to slowing down is definitely the sand. :)

- EDIT - Famine did it again... :D
 
karras85
i thought was the barriers...
compress the air in the left side and increase the resistance...
to much complicated...:dunce:

In real life, it's actually t'other way round. A similar effect occurs if you run very close to a wall as happens when you run a car very close to the ground.

A Formula 1 car has a HUGE amount of wind resistance, from the drag of the wings mostly. I read somewhere years ago that an F1 car at speed which closes the throttle but does not apply the brakes will experience over 1g of deceleration from aerodynamic drag. In other words, it's slowing down, without the brakes, almost as hard as your street car in a maximum-force panic stop.

If you're expecting to hear wind noise on an F1 broadcast from the on-car shots, you won't, because of the position of the microphone. I know you've already said you understand that. If you're expecting to hear wind noise from trackside cameras as the cars pass, you won't because the trackside cameras are simply too far away, hundreds of yards (or meters, if you like) in some cases. At that distance, engine exhaust noise is far greater than any other noise component. Even at 30 meters, there's too much engine noise to hear anything else. If the mikes are close enough, you hear the passage of the car, but it sound like a thump rather than a whoosh, as the car is close to the mike for such a small fraction of a second.

Remember also that the wind noise modelled in the game is supposed to represent what you would hear as the driver. That makes specially placed microphones irrelevant for comparison with TV broadcast sound, and it makes trackside mikes irrelevant also. Play back just about any replay and compare interior sound with trackside. How much wind noice is presented in the outside shots?

is louder in the inside... ur are right...
now.. im takling about the difference betwen.. f1 at 200km/h and mercedes 190 evo at 200km/h who is louder...

in the f1 car... all the air (exept the front wheels) is controlated to gain downforce... but in a stock car there are a front air ducts to the radiator and front breaks ventilations (and the cars with disk in all wheels... to the rear disks too)
but (for example) the distance betwen the headlight and the disk ventilation.. (when the bumper is) the air crash... dont pass trugh... or the lights too..
create an aerodinamic crash...

that suppose to make a diference in the speed sound volume...

Not so much as you'd notice in a Video Game! "Speed Sound" is a new innovation for games. I think it adds to the game, especially when you need to draft.
 
Famine
I use 'Copter Cam.

Famine uses copter cam?!?!? :crazy:

I would have never guessed that Famine. Not in a million years. That's prolly just because I only use the bumper cam.

I can use the roof cam just as well, I just like being closer to the road surface. I am absolutely horrible at copter cam... and I've only tried it like three times lol. :lol:

PS: It's good to be back. I've been gone forever, but I've come back since I started another game of GT. Thanks again for all your help on round 1, and its good to see that the smart ppl get to be the mods on this great board. Oh, and the Jack Bauer list -> A+ :cheers:
 
I sometimes use the behind car view when I just racing, if I'm going all out for fast laps Iuse the bumper cam.
