Cabin noise

MacLean

That is really effen good. If the noise is that bad, I would probably say jump on the deal.

For the ones that have used Roadkill or Dynamat have you noticed a night & day difference?

My experience with Dynamat was that there was that there was a slight difference when I did the hatch and more when i did the doors. (There is NO sound insulation in the doors) The two added up to a significant change, not night and day difference but significant.. and when I put on new tires there was even more..

The point being that, to me at least, no one thing made a "night and day" difference..but all three together did. It's still "sports car loud".. enough for me anyway ..but a lot more pleasurable especially on long drives. Guess if you're on the track it really doesn't matter..

Funny thing is that the other day I was driving my wife around thinking how much better it was..and on her own she mentioned that she thought it was loud!
She is used to an Accord sedan.

In my experience I went from really thinking I had made a very bad mistake to driving it every time I can with a big smile!! In fact I am about to go for a cruise right now!

What we really need is some accurate sound measuring device that can tell exactly how much difference these mods make..Anyone?

I have thought about this: there is a stretch of freeway that I travel that has various surfaces and really plays a symphony, or rather cacophony with the tires. The thing to do would be to use a recording measuring device and travel a certain section of road, long enough to get a good reading. Maybe 10 miles. Stay in one lane, at one speed as much as possible, A/C and stereo off & windows up. Take a measurement maybe every 10 seconds with the microphone in a fixed location, like attached to the inside driver side headrest strut. Install the Dynamat & repeat the test. Print out the graphs or plots and look at the difference in SPL at the same locations and elapsed time. There you go.

Well what is stopping you from doing just this?

Cash. None to buy the audio meter and software and none to pay some shop to do the Dynamat, especially since I don't want to remove the door panels myself or spend a day as a contortionist working in the hatch area

Cheech

There's an app for that!!

Did exactly what you mentioned. After installing the sound deadening liner in the rear hatch the level of noise in the cabin dropped 10db (using the iphone, same stretch of road, same speed, dry road.

Here is an interesting site that lets everyone hear what various db levels sound like..I wonder how much more you get with quieter tires?

dB: What is a decibel?

PS I just listened to the sound graphs..the math was not something I cared to deal with..
