Sound proofing experiment on the 370Z

370bluez

Anyways I was hoping to help others looking to quiet down the road noise and show them the approximate results with the route I decided to take.

As much as I searched I couldn't anyone that actually measured their before/after results.

5-6DB reduction is huge, and as I mentioned prior I haven't received that type of result on another car where I actually went full retard and covered the entire trunk since it seemed to be what most others were doing.

I received the same or better results on this car while only using 1/3 of the material!
