Frost King and Duramat Hoodliner: Completely ineffective at reducing cabin noise

I still have wind noise from the mirrors though.

 

Sorry for all the hard work @Colchicine , I didn't do near that amount, but did try to measure with a simple phone app. I was MOSTLY hoping for better stereo sound without a lot of money, so I just did the doors. I am a hearing aid guy, so I don't consider my 07 overly loud to begin with, but my inherited speakers were not the crap I thought they were, just hideously installed. I installed a phone app dB meter for reference, and really - you are correct - no difference. But what it DID do for me was make the stereo SOUND better. Noise reduction overall is probably minimal, but it does seem to tamp down the frequencies that would allow you to enjoy the sounds available. Thanks for your effort, and while "overrated" for noise reduction is probably true, the others I know that did it agree they have "better sound". And there isn't a meter that does that!

 

Interesting finds, glad you did this! I was going to get something like this for my truck since I gotta pull the walls off again soon.

I'd like to do a comparison with a decible meter or app as well.

 

No difference between resting my elbow on the center console, and holding it well above. I suppose my meat bag holding the meter helps insulate it from the vibrations.
