Unbearable Wind Resonance > 60kph/40mph - Toyota Yaris Forums

himself_himself · 08-10-2006, 12:12 AM

Hey,

Anybody with a 4-door liftback have wind resonance, to the point that hurts your ears? It's most obvious for me when either one of the rear windows are wide open and all others shut, driving at above 60kph/40mph. I've done some confirmation tests like driving at that constant speed, open one rear window until my ears can't handle, open one front window and the thumping noise is gone. Is it a coincidence of the cavity design that causes this? Maybe it's time I look into a spoiler INSIDE my car.

i have the 2 door and have to have the passenger window cracked open.

johnnyfive · 08-10-2006, 01:29 AM

this happens on alot of cars, just curious, did you try opening your fresh air vent with one back window open? might have to see if that does anything next time i am driving...

SmellyTofu · 08-10-2006, 05:14 AM

Tip. Don't open the rear windows that far. Maybe open it 1-2 inch. It's the movement (and lack of) between the cabin and outside that causes this ... there was a thread about it a while back on this topic.

i was goin about 70mph and let the two rear windows down (sedan) and the thumping and whopping was so severe that i didnt want to let them down all the way for fear of breaking something. the car shakes like a helicopter with 1 blade. i usually just crack only the front windows or just use the A/C

JustAnotherAsian · 08-17-2006, 02:34 AM

it happens on most cars with opening rear windows- which includes sedans, convertables (that little triangle window), small suvs, and whatnot. it's worse on sedans than others.

Yea, I get that "sonic boom" effect too, and its annoying as hell.

Having driven vans before, I never knew it existed!

I often want the fresh air circulating in the car, but dont wanna deal w/ the "loudness" of it at high speed if its either of teh front windows, nor it blowing hard against my face if i lower my drive side window..

but looks like i have no choice bc i need to atleast crack one in order to negate this annoying wind resonance factor!

Is this factor really this bad say w/ other comparable cars, say, Honda Civics, Fits, Corollas, Echos, etc etc ?

i get it bad on my LB.

I think alot of it has to do with how aerodynamic these cars are. I noticed I dont get nearly as much air into the Yaris with the windows down as I get with my boxey Jeep. This is causing a greater vacuum in the car and seems to make it much noisier.

i'd say "bingo!" to that, but i'm no expert. lol.

SimmZ · 08-17-2006, 07:12 PM

Samething on my sedan Echo and my sedan Cavalier. I almost never open back window. If I decided to put some aftermarket power windows in one of my two cars, I'll only do front.

jeff_o · 09-25-2006, 02:36 PM

wouldn't window visors lessen or solve that problem? has anyone tried? because they advertised that window visors lessen air turbulence and sound. i haven't tried though.

Yes, I wanna know this too! I hope they do!

We have a two door Yaris and the wind drumming noise is torture on your ears.
Has anyone tried the side weather shield to see if that helps.

Thank you
Greg.

Welcome to the forums. And you made a post... in a thread that has been dead for over 4 years.

Yaris Hilton · 05-29-2010, 09:35 AM

For anyone interested in how this works, look up "Helmholtz Resonator."

WeeYari · 05-29-2010, 10:01 AM

Since a new member has revived an old thread and will be looking to it for answers, yes, window visors do lessen the problem to a great extent.

I've read that the weather guards do make the situation more bearable... I'm getting a set from MI soon and crossing my fingers...

Would you rather have him start a new thread on the same topic without searching first? Right.
