Killing Road Noise, Results
#21
yes, please do post. I'd like to know where most of the noise is coming from. I've already insulated many areas (floor, trunk) but basically it had little affect.

Doing the doors alone with 3M Thinsulate and B-Quiet Ultimate knocked 3 db measured with a pro meter and noticeably improved stock stereo sound quality. The doors close like a 1980's Mercedes now. THUNK. Still haven't gotten around to the floor and rear tray after more than a year but intend to do so.
Thinsulate is essentially weightless; it's like cotton candy. Works really well at killing ambient white noise. I also added a blanket of it to the inside of the soft top between the frame and top. Folds up with the top and hushes tire noise from passing cars.
I also used some extra scraps of B-Quiet and Thinsulate on my old washing machine which was crazy loud. Cut 75% off the perceived volume when running in my closet. Now we can run it in the middle of the night or during a movie.

This member is a saint. I just used his recommendation on thinsulate and it has made my car a joy. I have my own post regarding this topic that I will update soon and link here for those who need a second opinion.

NVH is actually a pretty complex issue and manufactures spend a lot of resources addressing it. You need both a damper and frequency killer to get the low hanging fruit.

Pretty darn good actually. I recall the transmission tunnel getting very warm, even hot, on longer drives. It does not even cross my mind now. I did add a panel of Thinsulate in the one "hollow" panel in the soft roof, the portion with a double layer of material. I notice a big difference in the hot sun of Sacramento on that section compared to the single layer of roof material elsewhere. You can hold your hand up and feel the temp drop under that one panel. Wish I could do that for the entire top.

Hey cosmos, you’re an inspiration to my sound deadening project. I have acquired thick thinsulate but the problem is I have nothing that can cut it properly including new and sharp pruning scissors. What did you use? So far I have applied the anti vibratory padding similar to your bquiet roll as the precursor to the thinsulate and I have noticed much exhaust vibrations decrease. I only did the 30-50% coverage per “ zone “ as suggested behind bulk head and trunk area. I have not reached cabin yet since I am not ready to get to it without proper cutting of the thicksulate thinsulate. Also I am looking into some mass loaded vinyl type material or foams? what do guys think of adding that before the thinsulate on top of it? Ex) deadening roll on > MLV materials > closed foam material > thinsulate materials?
I’m sure the Mugen rep hardtop is causing a ton of sound reflection, I need to apply all upon the underside of this thing as well.
Thanks

Has anyone found reliable resellers for these products? The noise on longer drives gets very agitating to me and I find myself hopping in my wifes car more often than I would like instead. I drive most of the time with the OEM hardtop and the resonance and booming around the cabin can almost be worse than top down in a way.

Sound Deadener Showdown has a package for the S2000. Not exactly the same materials that @cosmomiller used, but similar.

"Net Weight Added to Vehicle in lbs.: 79"
79 lbs is a lot of weight to add just for sound suppression. Maybe they ment 7.9 lbs?
