Road Noise

Division

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.

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.

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.

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...

Second Skin

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 )

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.
