Noico mat lightly pressed by hand to untreated inner surfaces is considered soundproofing? I guess, by Russian standards... This material has to be rolled onto de-greased surface. It has texture on the aluminum side to judge the quality of the rolling job, has to be flat after installation. The coverage should be no more then 50% of each panel, in strategic places to lower panel's resonance frequency. This material, as well as Dynamat and others does just that, and sucks at soundproofing. Soundproofing means adding a layer of closed cell foam or other acoustic gasket material on top of that, then cover the gasket with MLV, mass-loaded vinyl. Then you get soundproofing, if done correctly. What is shown in the video is a huge waste of customer's money for the obtained effect and the quality of workmanship.

Wow, that's a crazy amount of work just to reduce the interior sound by a few dB!

Not to mention his mpg will suck.

Wow! This CX-5 will never be the same. I already can hear more rattles and squeaks after dismantling the inside. I'd rather sell my 2016.5 and get a 2017 than doing this. How much do think this guy paid for this job?
Hyperbole. Do your mpgs tank when you have the added weight of a passenger (who likely weighs more than the added weight of the sound deadening)?
Since the dB scale is logarithmic "a few dB" is actually a big difference.
I do wonder why they measure the sound on different devices. To me, that makes the results suspect.
While at the Honda dealer, I noticed the new 2017 CR-V's spare tire well is covered in the (shredded) cotton mat; you know the kind that looks like denim insulation. Not just a small square, but the entire spare tire well. I guess it was a large source of interior noise.
What about getting the bottom treated with an undercoating to lessen the road noise? I know when I test drove a Ford Edge, it was awful, but the salesman saifd they undercoated all of them before delivery and that one hadn't been done yet. I was thinking of getting done on the Mazda, just for giggles.
undercoated with what?
