I never met a project I didn’t like
I was wondering what people have done to reduce the diesel noise inside their trucks. Not the exhaust noise, just the engine noise itself. I'm going to have the engine out of mine soon so I want to do what I can inside the engine compartment while I have it out since it will be easier to do so.
I did some searching on Google and found a little info, but no magic bullet (which probably doesn't exist anyway). What I did find was a highly rated company in the noise reduction world called Raam Audio. Their focus is noise reduction as it relates to the audio world, but I did see some diesel people using their stuff.
I contacted them to see what they would recommend for my application. The first thing they told me was that their products weren't really meant to be used on the outside of the firewall...their stuff is for in the interior. He told me that they don't have a product that would stand up to use in the engine compartment. He told me specifically that it wouldn't last if being off-roaded, so I guess it would be a problem with dirt and such affecting the longevity of the product. When I asked him if he did know of anything that would work there, he told me that a brush-on bedliner product would work well there. He said this would help take care of low frequency noises and then if I applied their product to the inside of the firewall and other interior surfaces it would take care of mid-to-high frequencies. I feel like the IDI clatter we have would be a mid frequency noise, even so, unless I hear something different from you folks I'm planning on applying some brush-on bedliner (like Herculiner) to my firewall and then put the factory mat back in place. Then this summer I'd like to do the Raam Audio products to the inside of the truck to hopefully reduce the noise some more.
What have you guys done that has or hasn't worked? Even failures are helpful because it can help prevent future mistakes for the rest of us. Thanks!
