Reducing car noise from wheels
« on: April 07, 2009, 04:07:31 AM »
Hi everybody,

My car has pretty decent sound proofing, however there are certain tires (brands) that are quite noisy on the car and I would like to reduce the tire noise in the car.

I was thinking of putting some sound insulation materiel in the wheel housing (not exposed to the outside) between the wheel liner and the body of the car.

My current thought would be to put two layers of sound proofing, one a bit heavy and the other less dense. I don't want to repel the sound, I want to absorb it so that car is quiter outside and inside (in particular inside of course).

I don't want to put products like dynamat because I'm not interested in putting tar in the vehicule for the smell of things, for the weight and for the price.

Any ideas?

Sound dampening liquid will reduce road vibrations in the wheel wells...

Using MLV w/closed cell foam underlayment would be far better than dynamat.

Check out Sounddeadenershowdown.com. Most companies don't use asphalt based products anymore. You may benefit from adding a constrained layer damper to the advice already provided.

"You may benefit from adding a constrained layer damper to the advice already provided."
After reviewing the link provided by the prior post, as you can see the"Stock vibration damper on the front passenger side floor. " is only partial coverage therefore allowing the remaining exposed metal to resonate.
This is why a liquid dampening compound works better, FULL COVERAGE...this is key to quality sound reduction.
And keep in mind that dampening the metal is only part of the process, you still need a barrier for airborne sound....
