Default SOUND-PROOFING?

Anyone have an idea on reducing the road noise? It largely comes through the floor.

Thanks,

Richard

Dynamat works great and will be a huge improvement in terms of noise reduction.

Although dynamat is probably the best product on the market for noise reduction, remember 2 things. 1, it is expensive, 2, its heavy, and we all know weight means less MPG. It might not be much, but its a factor. Good Luck.

Another option for sound proofing:

And another tip - most of the road noise in my Insight was coming from the rear well area.
As an experiment, I borrowed a heavy down comforter from the bedroom and spread it out over the cargo area, and was careful to not block the vents. Next commute to work I noticed this considerbly reduced the road noise. So I only put sound deadening in the spare tire/cargo well area.

Regards,

I used "Brown Bread" (in my Insight, Cheaper then Dynomat and worked like a charm!)

Dynamat is for sound systems, it helps keep sound within your car. It does little to reduce sound from outside your car. Save your money on those expensive mat products.
I belong to the Corvette Forum and most Vettes are using a simple product you can buy from Lowes, or Home Depot. Frost King. It has thin aluminum on both sides and does an outstanding job of sound proofing. I have it in both my Vette's. Just use spray contact cement and go for it.

Link to give you an idea of what I'm talking about. This person pre-cuts the parts for installation in a Vette. Lesson's installation time.

"Frost King"...Thanks for the tip. I went to Home Depot, and found this to be a water heater blanket, fiberglass fill with a backing. Is there an ideal or recommended thickness?

Thanks again,

Richard

Richard S, Please check out the site I posted. The product is not fiberglass. It appears to be metal (Aluminum) on both sides with foam in-between.

First, thanks to everyone who replied, and for your great advice! I had the car "dynamatted". While the car isn't as quiet as I wish it were, it was a significant improvement. No change in gas mileage noticed from dynamatting, yet. BUT, I previously changed the stock tires to a more comfy-riding tire. My mpg drop from the tire change was 12%, but the car rides much better, and with the dynamatting it's an overall improvement. I know now that its "as good as it gets".

Thanks, all!

Richard S
