bushroot Posted March 31, 2014 Report Share Posted March 31, 2014 Now that it's warmed up enough to sound deaden my Scion, I'd like some advice about MLV and how much of a difference people have noticed in noise floor by using it. It's one thing to read on the interwebs about how great it is and all, but how much of a difference did you hear between using a CLD dampener and using CLD/foam/MLV?

trumpet1 Posted March 31, 2014 Report Share Posted March 31, 2014 Now that it's warmed up enough to sound deaden my Scion, I'd like some advice about MLV and how much of a difference people have noticed in noise floor by using it. It's one thing to read on the interwebs about how great it is and all, but how much of a difference did you hear between using a CLD dampener and using CLD/foam/MLV? CLD damper mat is for treating panel resonances Closed cell foam is for isolating panels and hard parts that are touching and making noise Mass loaded vinyl is for blocking sound, such as outside road noise or to reduce interference from sound coming through the door from the back side of the speaker CLD alone is usually used incorrectly as a "silver bullet" sound damping solution. One product can't treat the variety of acoustic problems in a vehicle. CLD has been very helpful to quiet my buzzing door panels, but adding CCF and MLV from www.sounddeadenershowdown.com using Don's instructions and the vinyl cement was a very beneficial addition to my car. It noticeably lowered the annoying effect of road noise which was coming right through the doors, and it improved the midbass response as well. My Saturn is notorious for being noisy, even when these cars were new, so your results may vary if your vehicle has better noise treatments from the factory.

bushroot Posted April 2, 2014 Author Report Share Posted April 2, 2014 Well, I ordered the MLV. It's some expensive shit for what it is. We'll see how I feel about it. Link to comment Share on other sites More sharing options...

bushroot Posted May 2, 2014 Author Report Share Posted May 2, 2014 http://www.stevemeadedesigns.com/board/topic/181354-scion-xb-front-stage/page-3 Scroll down towards the bottom of the page. I installed CLD mat, closed cell foam for decoupling, and MLV. The car is much quieter now. I have an exhaust leak under the passenger seat area which I can barely hear now. My rear doors are still undampened, so I can hear them. I would suggest taking some time with the rear hatch. I think that was the most challenging thing to sound deaden. I put CLD mat everywhere I could get to and it did nothing. In the end, I took closed cell foam, rolled it tightly, and taped it. I put these between the inner structure and the outer shell. I can't believe how quiet it is now. If you can't visualize it, I'll be working on the car again this weekend and I can pop the cover off and take a few pictures.

bushroot Posted May 2, 2014 Author Report Share Posted May 2, 2014 Also, the only thing I found that sticks well to it for the seams was Tyvek tape. I know most guys glue it, but meh... Link to comment Share on other sites More sharing options...
oldsoundguy Posted May 7, 2014 Report Share Posted May 7, 2014 I put it on the back panel of my extra cab truck and the floor. I didn't glue it down just laid it down and used aluminum tape to hold it together. The truck is much quieter. I used a material we have at work to sound deaden HVAC units. Its about 3/16" thick rubber with a foil back on it. I got it for free as we had some scraps. Its heavy but does a great job of blocking out the sound of the road, exhaust and tire noise. 80prs Arc Audio Xdi 1200.6 (using active crossovers) Freaking awesome amplifier Incriminator IA 10.1 Focal PS 130v 5.25 (doors) 4" Faital pro Neo (kick panels) 3" Faital pro Neo and focal tweets( dash) DC Audio level 3 12" custom box designed by joex built by me AGM front, XS 750SE batteries rear DC 180 alt 99 Toyota Tacoma extra cab http://www.stevemeadedesigns.com/board/topic/179476-my-small-build-turned-into-the-ongoing-build/ Link to comment Share on other sites More sharing options...
