Sound deadening materials for a car can be purchased at motoring stores. There are a variety of brands and materials available. Some can be purchased direct from manufacturer. eBay has a variety of options available.
No sound.

Most noise control used in vehicles today consist sound deadening spray or sound deadening mats. The spray or mats are applied directly to the metal, underneath the floor mats and inside the door panels.
Sound deadening like fatmat, or dynamat
sound deadening, insulation, furniture feet felt is soft and filled with air so it doesn't scratch surfaces and limits heat/cold transfer and reduces sound transmission
are you sure they are both cats. some exhaust systems have a resonator after the catylitic converter to help with sound deadening
Yes, It will block outside noises and make the stereo sound better, only time you should not, is when you are building a car to drag race with, becuase weight slows you down.
To effectively reduce noise pollution in your home, you can implement sound deadening for walls by using materials like acoustic panels, soundproof curtains, and foam insulation. These materials can help absorb and block out unwanted noise, creating a quieter environment. Additionally, sealing any gaps or cracks in the walls can further enhance soundproofing.
The only reason that I have heard of for insulating interior walls was for sound deadening efforts. There is no heat gain or loss advantage to insulating interior walls.
The sound found in "bought," "thought," and "caught" is known as the "aw" sound, which is a back, rounded vowel sound.

Yes, memory foam can be an effective sound deadening material due to its dense structure, which helps absorb sound waves and reduce noise transmission. Its ability to conform to surfaces allows it to fill gaps and minimize sound leakage. However, while it can dampen noise, it may not be as effective as specialized acoustic materials like mass-loaded vinyl or acoustic panels. Therefore, for optimal soundproofing, combining memory foam with other soundproofing materials might yield better results.
