Can I quiet my car's cabin noise?
Q: I have a compact car, a Toyota Yaris, and although I love the thing it's kind of loud on the freeway. Is there any way I can quiet down the cabin noise?

We recommend 3M Sound Deadening Pads, a new product that costs $14 a roll. The idea with this thin new stuff is to use it like a shock-absorbing sticker and soak up the noise-making vibrations that transfer into the cabin. Installation is done by cutting out patches and sticking them to key spots on the sheet metal. The easiest places are the firewall and floor because you can get to them from outside the car and without removing any parts. If you're adventurous, remove the inner door panels, carpet, and headliner, then stick deadener on the inside of the outer door skin, floor, and bottom of the roof panel.
Another, more expensive solution is to fit quieter tires next time your rubber wears out. Many retailers and online reviews rate tires by how much noise they generate.
