Reducing Noise, Vibration and Harshness (NVH)
Not many people can afford a top of the line, luxury car like a Lexus, Mercedes, BMW or the like. But many would really like to have the ride comfort of such cars. These cars seem to just glide over road imperfections without jarring you. What is the secret? On top of having a suspension that is well tuned, many of such cars have automotive polyurethane Foam in the hollow section of the cars.
The Foam actually reduces noise and vibration by absorbing sound and vibration waves that travel up and down in the steel members of the car. Due to car chassis construction, with large thin metal walls, resonance occur within the car section like the A , B and C pillar, as well as doors and side sills. As the driver and passengers is surrounded in the car chassis steel frame, it is like a having a surround sound. But in this case, it is surround noise!
There are several types of automotive polyurethane foam. There are flexible foam, semi-rigid foam, rigid foam and finally structural foam. The first 3 types are designed to reduce noise, vibration and harshness and will not make the chassis stiffer. Structural foam like AUTOFOAMTM will also make the chassis stiffer. They have been used by car tuners to make the car handle better without adding much weight to the car.
However a word of warning. Before you go out and start pumping foam into your car sills and pillars, there are the correct type of foams and in-correct type. Do not, get DIY foam for your home. Only get automotive foam as there are formulated to cure in close air-less environment. If you use the wrong foam not designed for use in cars, you might just end up with a gooey mass that you can't remove.
