Road Noise
 

Does anyone have problems with road noise. I am partially deaf and my wife says she cannot hear while on her cell phone. Anyone notice road noise.

I am looking at FatMat Sound dampener for Hood and interior.
Has anyone had this done?

I hear quite a bit road noise in my MT Touring with SP, what roads
you're on makes a big difference as well. I haven't made adjustments
and it seems less of a big deal with time

the only thing that i dont like is being able to hear rain splashing around in my wheel well

Tell her to turn her cell phone volume up, or to leave the phone off while you're in the car.

Nothing more annoying that being force-fed half a conversation within an enclosed area.

That said, if you must, rig it up to the blue tooth system if you car is equipped.

Hi Guys, Happy New Year!
I have about 1200 miles on my new Z (base model) and love everything about it except the road noise. I drive about 45 miles to work, and if I could reduce the tire noise it would be the perfect ride for me. I have sent a message to the auto noise reduction company "second skin" to see what they recommend. People with 'vettes seem to have good luck with their products. I will report their response when I hear from them. Anybody else tried to reduce the tire and road noise?

It all depend on the road you travel...

I take the road less traveled by and that has made all the difference...

You are absolutely right! I am being picky, and if I can't make it any better I still am nuts about the Z. Just looking for ways to fix the one thing that would make the commute even better. I imagine Nissan went easy on the insulation to save weight, and I wouldn't mind giving up a few tenths of 0 to 60 time to subdue the road noise. I do like the exhaust and motor sounds, and if we could reduce the road noise, those sounds as well as the stock radio would be even better. Has anybody tried a different tire? Just curious. And I really do like the idea of taking the road less traveled!

There are number of threads about sound deadening on the boards - having done it personally, I can say it made my commute much better. Conversations both in cabin and with my hands free (through stereo) are much better. No more yelling. All and all, it was the best thing I did. I don't track my car- the extra weight didn't bother me at all.

Its still a sports car however, I wouldn't be expecting pin drop quiet in the car - but proper deadening (both mass dampeners and absorbing foam) does help.

Great info. What did you use? Thanks . . .

i drive an s2000 for the last 5 years and still do, so i think the noise doesnt really bother me. The Z to be in terms of sound noise is like a luxury car to be. lol
But dynamat or other stuff would help, i helped with my s2000 along with a hardtop.

:rofl2:.....+1

I just installed 40 sqft of second skin's damplifier and 9 sqft of luxury liner (about 26 lbs total). The damplifier went in the doors, floor, and rear section and the luxury liner went in the back hatch area. The noise was significantly reduced, but not what I would call quiet. It has definitely increased my enjoyment of the car. If I had to do it again, I would have went with the damplifier pro and luxury liner pro and drop the sound a bit more. The extra 26 lbs was definitely worth it.

heres an idea, turn your music up.;)

Division, what products did you use and did you take any photos of your completed job?

For me the noise is in the wheel wells and the hatch in the back, sounds like the hatch is closed all the way, so Im wondering if just a better rubber seal thingy would help that some and some type of spray on for the wheel wells. But the 10in sub I now have kinda blocks all the noise.

Tire brand/design may have to do a lot with it. When I first bought my Z, the tires used to produce a droning-like sound (kinda like a low howling). When I got new tires, I went ahead and bought Dunlops. The "howling" ended. Also, the ride improved like 50% (i.e. a less jarring ride with the Dunlops, versus the Bridgetown Potenzas).

I have asked several people about the tire issue and most have stated that the noise that is the most common is the road noise. Some have suggested more of a sound barrier would be the best bet however I have as of yet been unable to get the specs. It would be nice if we had some pics showing what really works and what doesn't.

Glad to hear you like our products.
We are gettin gready to add a new package to our website specifically for 350/370z customers.
9 sq feet of Luxury Liner is not really enough to do much damage, but it will help in the specific area it is used.
Our package is going to be something like:

- 60 sq feet of Damplifier
- 36 sq feet of Luxury Liner Pro

This would make a very good impact on unwanted road, engine and exhaust noise and would add about 60 lbs or so.

Always remember, there are 2 tupes of noise to focus on in any car.
1. structure borne noise - reduced with a vibration damper
2. airborne noisel. reduced with a noise barrier

A combination of both products will reduce both types of noise.

Another thing you can do that helps a lot is to use a vibration coating in the wheel wells. This is different from a rubberized undercoating (they do pretty m uch nothing for noise). There are a few companies that make good coatings:

Quiet Car
Stealth Kote
Noise Killer

We also make on called Spectrum
These are acrylic coatings that dry to a very har, yet elastomeric finish. The absorb the vibrations and reduce the noise.
Applying a 2 mm thick coating to the metal wheel wells and quarter panelos is a great way to kill the road noise.
The closer you kill the noise to the source, the less noise will make it to your ears.

Hope that helps!

engine noise wanted, exhaust noise wanted, road noise not wanted so what would be best for this? The rear wheel wells need something and the hatch area is more of an air noise in my case only a little noise from underneath.

In order to tartget specific type of noise you need to treat the area closest to the noise.

Road noise is a bit more difficult than the rest, since there are 4 tires, placed on all 4 corners of the vehicle.

I would start with 2 gallons of a good noise coating in the wheel wells and quart panels on the underside of the car
Treat the sheet metal that surrounds the tires as well as inside the quarter panels if you can access them.

Next, go for a vibration mat on top of the wheel wells in the hatch (inside the car)and under the hood. Under the hood might be difficult. Some cars only have a small amount of sheet metal exposed from the top of the wheel wells. Just do your best.

Last, use a noise barrier inside the car on top of the vibration damper surrounding the wheel wells and quarter panels.
You may have to do a bit of the trunk/hatch floor with the damper and the barrier becuase of the way the noise travels through the sheet metal.

If you used our product you would go with something like

Damplifier Pro or SPL Tiles (as the vibration mat)
Spectrum (as your acoustical undercoating)
Luxury Liner Pro (as your noise barrier)

There are lots of good product out there, and I am obviously biased, being the owner of Second Skin so do your research and see what works for you. Our product can be expensive if you go with the better ones we offer, but you get what you pay for.
We also have less expensive options for people looking to save some money as well. Again, look around. Whether you use Seocnd Skin or not, there are deals to be found if you do your homework.

Hope that helps!

lmao ya tell her to STFU or :gtfo2: :roflpuke2:

After living with the (expected) roid noise for about a month-and-a-half now, I'd say the only objectionable noise comes from the rear wheel wells. All other noises are symphonic. :driving:

Road noise
 

I have found that most of the unwanted road noise is from the rear. I just finished putting on Takeda CAI and Invidia Q300 exhaust. While I had the car up I noticed that the under the rear where the spare sits is just plain aluminum with out any undercoat like the rest of the vehicle. Need to take a look at that more closely. I am going to purchase some sound deadening material , do not know which one yet and start in the rear hatch area and also under the rear of the car with some spray material. I will try to borrow a noise meter which measures the decbels and see it I can make a determination as to where the most noise is coming from.

Good news is that when I get on the throttle the only thing I hear is the CAI and the sound of the exhaust. Bad news is when I try to be easy on the ( which is almost never) gas I hear the road noise.

All this dampening is well and good but what are you guys going to do in the spring, summer and fall, drive with the windows closed????

No me...The noise is not that big of a deal...

Where I live, we have grooved freeways. The road noise is so bad that I can't hear the sound system. Other than that, I love the car. Currently in the process of installing Dynamat. Will advise upon completion as to how much road noise took a dixie...

Remember, if you install dynamat and nothing else, the road noise will only be reduce by a small degree.
Products like Dynamat Extreme, Hushamat, Damplifier PRo etc, are vibration dampers. They are designed to reduce structure borne noise.
Exhaust noise, engine noise, and road noise is comprised of structure borne noise and airborne noise. To reduce airborne noise, you need to use a barrier. If you are set on Dynamat product, go with their DynaLiner. this is a very solid performing barrier that will get applied on top of the dynamat extreme.

Remember, if you only use one product, you only attack one of the noise problems, and you ignor the other half of the equasion.

Large amount of road noise in this car. That said... the bluetooth system in this car really does work quite well. With all my mods, I def have to roll up the windows when I want to use the bluetooth but have no problems when I do. (I just don't shift above 4k when on the phone :icon17:)

Am I the only one who is backwards and enjoys the road noise?

I seriously like it. I'm not quite sure why. It never really gets on my nerves at all, even when I'm trying to talk to someone next to me or listen to music.

Maybe it has a lot to do with what I came from, lol.

It doesn't bother me one bit.

When on the rare occasion that either my exhaust or music aren't drowning out any possible road noise, I'm in the car with my GF and neither of us notice anything out of the ordinary in terms of noise.

Yes, it's a big problem in my 2010 base model. I here it's a basic design flaw.
I am investigating possible fixes now. None so far seem easy. Have to take apart the interior

He said "here" :icon17:
Is a sports car. I don't know why people complaint about the noise. Yes, some tyres will make it a bit less noisy, and you can add sound proffing material. In the end, if you (with that I mean all of us) want a quieter ride then we should have bought a MB or BMW for that matter. I don't think is a flaw. You want it lighter... then sound proffing won't be added.
I did my homework before purchasing the Z. Not to mention this is my 4th Z, but I knew what I was getting into. I knew all the "goods" and "bads" before the purchase. I recommend to everyone to do the homework, not just focus on price and horse power numbers before signing the papers. I'm not saying you (with that I mean all of us) should not complaint and not to try to get a better product, that's the beauty of democracy. What I'm saying is some of us, drive a Z and now they realize how noisy the car is, how noisy the clutch can get, there is no much interior room, the brake pads are really crapy, and so on.
For example, a coworker wanted a Z so bad, he was going to purchase one a few weeks ago. He was talking about a Z this and Z that non stop for two weeks. Funny thing is, he thought the vehicle was a V8. Now he does not want one. Do the homework people! The internet is a marvelous thing, besides looking at porn.

OEM Bridgestone Potenza'a on the sports model is the real culprit. I have snow tires on and the noise problem has disappeared. It shall return when I put the Potenza's back on in a couple of weeks.

This has been discussed at length on here, and this is an old thread. Some folks have suggested adding sound-damping materials like DynaMat. Others have had luck with just upgrading their tires. I understand the Continental DWS are pretty quiet.

Personally, I don't mind the noise.

Yeah put your tampon in and drive it.

I have the DWS and is a bit quieter, but don't expect to be able to have a quiet conversation while doing 65+ mph.

Yea, the noise is not even a factor with me. The Super Sports I just had mounted are even louder than the Potenzas.:icon14:

Every girl ever in my 370Z (with oem exhaust/intake {for now :tup:} ) :

"This car is loud!"

Me: :facepalm:


Thats ok, its not like my 350 with 2.5'' piping coming off the rear turbo and neighbors complaining. Thats a whole different animal. I personally like the road noise/ exhaust noise. Cant wait for the F.I exhaust and stillen g3's though :yum:

I thought that my Z wasn't so loud, then two weeks ago I got new hearing aides and wow, it is loud. But I love it!
I finally heard the "rasp" that folks with hfcs have talked about.:bowrofl:
