What is the best sound-deadening material for cars?

I’m looking for a good sound-deadening product for my car, but between mats, spray foams, and suppressors, I’m not sure how to choose. What is the best sound-deadening material to use for cars?

The best sound-deadening material for cars comes down to a matter of preference—below, we’ll cover a few pros and cons of the most popular sound-deadening materials on the market: Sound-deadening mats:
  • Popular for thick butyl rubber coating that effectively blocks out extra noise
  • Better for covering larger spaces
  • Durable
  • Expensive, close to $200 starting price
Sound-deadening sprays:
  • Great for getting into those hard-to-reach rattle-y places, like your engine compartment or doorjambs
  • Significantly cheaper, most 16 oz. cans cost between $15 and $20
  • Use significantly more to achieve the same level of sound blockage
  • Messier to use
