Boom Mat Sound Deadening Headliner Reviews
make a huge difference with temperature and reducing road noise. alpine stereo does sound better as well. keep in mind that only the pads that go on the freedom tops are 1" thick, the rest are 1/2". really need to remove top to install properly.
These definitely make a difference. I would give 4 stars but the backing didn't peal off very easily, looks like the patterns was double cut in a few places which caused the backing to only partially peal away. The filler strips weren't marked like the instructions show.
I have a serious noise issue in my JLU, and being an engineer that works for a large audio-visual integrator, the first place I went to solve some of the acoustics was the hardtop. Lots of noise bouncing around in there, let alone the wind noise.
I measured the pre-installation decibel levels with a c-weighted meter (wish I had used a spectral analyzer, you'll see why in a minute); idle was just above 70 dB SPL, and driving straight into a 20 MPH headwind at 75 MPH, I was running 95-104 dB SPL (I now know this is indicative of a much larger issue with the front seal on the freedom tops).
The moment began installing the rear side window boom mats, I heard significant changes in the acoustics of the vehicle (I had my radio jamming, as I'm sure most of us do when we work on our cars), and the farther along my installation went, the better the overall acoustics felt. So, the radio actually sounds worlds better, as the Jeep's acoustics are vastly improved.
Installation was easy, and the custom-cut panels look great.
Idle dBU SPL dropped by 3, exactly as they mention in the description.
What's shocking was the reduction in other road noises; my knobby tires always caused a low frequency reverberation (at low speeds) that drove my wife insane; these are now gone, for the most part, at all speeds. Of course, you expect a lot of reverberation reduction when matting foam, anyway; but I never realized quite how much there was until installation.
At highway speeds, though (75 MPH), I ranged 80-95 dB SPL. That's a SOLID 10dB SPL reduction, and from a perception standpoint, it now sounds HALF as loud in my jeep at highway speeds. I was actually able to hear a number of other problems, mainly with how the freedom panels aren't correctly interfacing with the front windshield, and I'm currently working to eliminate those issues to make the cab as quiet as it should be.
I highly recommend this product; even if you don't have the dreaded freedom panel wind noise issue, it really changes the acoustics of the cab an abates other noises you're not even aware of!
