Cabin noise

pf62

I know what your saying about the ARK drone. Did the dynamat but it did little to quiet the drone. Put a few hundred miles on it and it got a little better. As much as I hated to add more weight, I got a 12 sq ft piece of dynapad and put it under the carpet.

Wow, big difference. Just traced the carpet on the dynapad and cut it to fit, one piece, about 10 lbs. The quality of ride and sound is tons better and can now hear the exhaust and not the drone.

Glad to hear.!.but I think the real big difference is in dynamating the doors, as well!!! Its just so much more enjoyable on long drives...

Thats next on the list. Almost have enough left over to do it. Probably need another piece to do the doors, that is where I hear most of the road noise now. Just want to make long drives even more enjoyable.!

It won't help the ARK drone though, just road noise. One of the reasons I traded in my E92 M3 was because it was too quiet and did not sound like a sports car. Their are annoying noises and sounds of the open road. I guess it all depends on individual taste of how you want YOUR driving experience to be.

The dynapad took care of the rest of the drone for me. Certainly not looking for a limo ride, just reduce the bad noise from the road. Where I live they do alot of tar and chip road resurfacing, very rough surface which the Z amplifies.

A prouct called Frost king Duct Insulation. 12" wide 15ft long. Foil on one side and SELF ADHESIVE on the other . Thicker than Dynomat Extreme. Cost for 2 rolls equals 30ft long 12" wide=$40.45. I will let you know how it works and post pics. Says it insulates and STOPS vibrations. This will probably help since Im buying larger tires soon. Will do my hatch area . Looks exactly like Dynomat.

You mean you put the dynapad under the carpet in the hatch area? I"m thinking about doing the same thing but wasn't sure if you meant the hatch area or some other area?

Thanks

Anyone tried putting dynamat on the underside of the corrugated plastic cover (along with doing the actual hatch). Wonder if that would help as well?

Sarcasm coming.......

That corrugated plastic has a name, it's called coroplast.

Sorry, I had to be a smart arse. It's not very often I can use terms I work with on a car forum.

Coroplast - Manufacturer of Corrugated Plastic Sheets

I'm not sure you idea would help or not. It was my understanding that it's the actual bonding with the metal of the car that creates the sound absorption. But on this one I could be totally wrong.

Yes, under the carpet, on top of the coreplast. Very happy with the result. Wish I would have tried this before dynamat, might have been enough for me.
However, the combination of both has transformed my ride from what it was.

Yea, something thicker than dynomat. I saw dynomat, very thin. Im thinking 1/2 inch thick insulation under the carpet in the hatch area. Overall, road noise never was much an issue cause its a sports car anyway. But im lookin at larger tires and it may be more of a concern. Im going to Lowes to check out some insulating products.

This idea seems a fast and simple way to at least take a small but effective stab at some of the road noise. Of course further dynamat'ing etc would be more effective.. but if simply finding something thin and foamy to place under the hatch area carpet...makes a difference, I'm in. Please let us know your results!
