Cabin noise

scottIN · 02-02-2012, 09:14 AM

My Mercedes had carpeted wheel wells. My wife's mini countryman does as well. Never a peep no matter how much gravel you throw up. In my Ridgeline, I only hear the really big stuff-the tires I'm running right now are real bad about picking up the standard size rocks used on gravel roads and tossing them into the wheel wells when you hit about 60 mph.

It's called Zee-Broom.

I'll probably do the dynamat thing (or another cheaper brand) while it's open. I just hope it doesn't take all day to do it like some have said.

I'm going the Duramat Extreme route. Just ordered 36 sq.ft. and will do the hatch and the doors. I hope the keeps the debris noise down. I like the engine and exhaust tones, but the road and debris noise is no joy to my ears at all.

I'm in the same boat. First time I drove my car I thought 'What the hell is happening?' Then I figured out it was pebbles. Might as well just shake a tin can full of rocks by your ear.

And I'm in Injunana so we've got tons of gravel and sand on the highways right now. Just drove to the next town over and they had been putting sealcoat down and then tossing gravel over it. I'm about deaf now...

I am going to do the Dynamat Extreme and if someone figures out if the spray or brush on deadener works, I might do that, too.

I don't mind that the tires pick up every loose item on the road or the fact of the noise it makes in my wheel well. I'm more worried about the pebble that gets kicked up while turning which then scratches my paint. This will be more of an issue when I install my wheel spacers.

Get the touch up pen from Nissan. Enjoy your car.

well I am glad I am not the only one hearing the pebble noises. I just noticed them the other day, then again I just got my Z

I hadnt noticed them before because the radio is always on. As for the interior noise, coming from a 2008 STI, the Z is a caddy by comparison... well maybe thats a bit of an exaggeration but it certainly is not as loud as my STI was on the inside.

Dynamat will add a ton of weight to your car.
Get this: Custom Lexan Cabin / Trunk Divider (Ferrari esque), pics inside
Then get some foam pieces to fit into the space under the harness bar

My Dynamat arrived tonight and I will get started on the install this weekend. I love listening to rock, but not each and every rock kicked up from my tires. It has to go!

Please post back when you get done about the "pebble noise" difference. I'm very interested to know your findings.

Thanks ----- Bonzo

I will run some db numbers with my iphone db meter app and report back with some figures.

FINALLY, some real scientific numbers!!!!

No, seriously, just your own observations about the pebble noise specifically (not road noise or tire noise etc) would be great.

Thanks ---- Bonzo

Can someone take pics? When I had all the trim pulled out of the trunk last night to install LED back up lights, there were a lot of places around the wheel wells where dynamat would fit - as long as the trim isn't right up against the metal. I know Dynamat isn't real thick, but I don't want to get into a situation of having to pull it off becasue the trim won't fit back in.

FWIW-it's scary to pull that trim off. You have to pull like hell on some of it. I'm sure it will be easier the second time but that first time you're sure you're going to break something.

Check out my prior posts (from the beginning) on the topic, they should answer most of your questions. PM me if I can be of further assistance.
