2011年2月26日 · For anyone thinking about installing a full sound system, I would strongly, strongly recommend spending a few hundred bucks on mass loaded vinyl and closed cell foam in addition the standard sound deadening. The difference with MLV/CCF in the door panels and rear hatch compared to sound deadening only is incredible.

2013年2月25日 · CCF is going to be your best bet. It works better stacked on top of deadener, but deadener is heavier. CCF is lightweight. You could add 100 sq. ft. and still easily be under 50 lbs. added. This is for treble treatment mostly. It's most effective in the 12kHz+ frequencies.

2020年8月12日 · My understanding is that the only way to reduce road noise is through blocking sound (MLV). I've read reports of people not getting good results from mlv and CCF on top of CLD applications for road noise reduction (presumably because …

2013年1月6日 · MLV requires an isolating layer to work as a noise barrier. If there isn't a layer to decouple the MLV from the panel it will transmit the noise by way of vibrations. The installation method provided by Sounddeadenershowdown.com is brilliantly simple and it allows for the product to be removed and reattached at will.

2013年7月14日 · CCF/MLV absorb/block noise and provide a few degrees of thermal insulation. A combination both treatments is required for significant improvements. Jute padding is also a useful treatment material to fill areas to displace air pockets.

2021年5月2日 · Absolutely not. As you said, you read our article and us mentioning we won't bother selling an MLV.. well, we sell a CCF lol. Almost every single car audio branded foam I've seen and worked with was one of two types of foam. Same material used, just different formulation and manufacture method.

2018年7月24日 · CCF is meant to reduce sound/vibration transmission BETWEEN the layer of CLD (in your case Dynamat) and MLV. If you are not adding MLV there is NO reason to add layer off CCF. That being said, you WILL get the most reduction in panel resonance and road noise, with the commensurate increase in listening SQ, by using all three materials in a CLD ...

2018年1月11日 · I've made a little progress on my sound deadening project. Specifically, I've "wrapped" my passenger wheel well with CCF stuck to MLV. MLV faces out; CCF faces existing, stock foam padding. Ultimately, I used (6) pieces of the combined CCF/MLV. Two approximately triangular shaped pieces reach up into the "outside portion of the wheel well.

2011年8月5日 · In short, to keep road and exterior noises out, you use MLV. To cut out rattles and keep sound IN the car, you use CCF. Deadener and CCF are not created to reduce road noise.

2018年12月16日 · Back in the summer of 2017 I wanted to test a common rule of thumb: mass loaded vinyl should always be decoupled from nearby surfaces, and closed cell foam is the right material to do it. Many of you kindly donated materials for this experiment and I am very, very thankful for it. I am thrilled to finally finish and post the results.
