2014年5月31日 · Not only does it help with the sound, it helps with exhaust gases coming through the floor pan. that was the main reason I used it. I used the thinnest sheets I could get. It ended up adding 28lbs extra pounds to the car. But it was worth it. I could of got thicker sheets to help even more with the sound deadening. But I track my car from time ...

2022年4月3日 · Hey all, looking for some sound deadening tips and tricks DIY. The vehicle is a 2011 supercrew F150 and a giant echo box. I'm looking to do it on the cheap and it doesn't need to be pretty. Looked into dynamat but I'm a cheap ass.

I drive a G35 and man does it love to drone around 2-3k rpms, even with my art pipes and a fat resonator in the mid pipe, it drones like crazy. I have shorty headers, art pipes, z1 y pipe and exoticspeed r1-t catback. I have looked in to sound deadening and there are so many options from butyl only, butyl with mlv on top or ccf.

2021年6月13日 · Call me biased, but i think the independent objective testing done in "The Deadening" Facebook group allows me to say that ResoNix has a serious leg up on everything else on the US market (that has been tested so far, including second skin, dynamat extreme, noico, kilmat, NVX, roadstage, and even Sound Deadener Showdown, etc..).

2021年8月7日 · The problem with sound is logarithmic. Every 3 dba increase is double the sound energy but you barely perceive it. To hear that sound is 2x louder, it has to increase 10x in power. Conversely, cutting the sound energy by half results in a 3dba change, which is barely perceptible. You can fill your car with Dynamat and it'll drop maybe 3 dba.

2018年5月5日 · Sound penetration seems to depend on the wall thickness relative to wavelength, so longer wavelengths go through walls (and car windows) easier. Also, higher frequencies are more likely to be absorbed and coverted to heat. Deadening still helps though - basically dampens the sound in the door like holding a cymbal, or the felt mute on a piano ...

2024年3月25日 · Best sound deadening material I am in the middle of a Cadillac hearse into an Ecto-1 replica and after installing the exhaust the interior noise in the rear seats is... excessive. I know dynamat is the go to for everything, but we're a charity group on a budget.

2023年3月9日 · Sound deadening will reduce some rattle on the panel it’s applied to but more importantly it prevents the panel from resonating and killing off mid bass tones. Any deadening will be an improvement I think. Sound deadening seems like one of those things where a little can go a long way and a lot can turn a car practically luxurious feeling

2022年10月14日 · Sound deadening butyl on its own can also vary very drastically. Just the fillers can range from sodium carbonate, CaCO3, clay, bitumen, and more. These are just fillers, then there are actual additives that help achieve the desired …

2020年4月24日 · Thanks for your input. I've been reading a lot about sound deadening and I've found this. Basically it says that CCF is not a good decoupling layer. So the best options are: A) if you don't have much space: CLD + MLV and leave the MLV as loose as possible. B) if thickness is not a problem: CLD + pillow stuffing / 3M thinsulate + MLV.
