Sound Deadening is a WASTE OF MONEY... done wrong.

Just a quick video explaining how sound deadening works as well as the proper, and cheaper, method of getting the LEAST BANG for your buck!

This is exactly what I thought when testing these mats on my coffee machine. I wondered why everyone on KZbin covers the whole car, even if they claimed to be professionals.

Because in the background these are the people selling this stuff😉

I nearly died laughing. The combination of the "thunk" sounds, the screenshots, and your humour was perfect

[@imranmalikE72]

Well explained. That's why the car manufacturers have just pasted small stickers of sound deadening in fenders etc , they haven't covered all.

[@abelscaliber7969]

Hell they even tell you 25% coverage is optimal and any more after that has a diminishing return that’s very steep

[@AlCapone-tr5lb]

Wow! That has to be the most rigorous, in depth, comprehensive, measurable, data driven, scientific test ever conducted! You should apply at NASA! 😂👍

[@markallendelisle]

Same reason the moon is 25% the size of earth #mindblown 😆

You’re right - this stuff is to take the resonances out of the metal to deaden it. People are using it to block the roadnoise so they can hear the music more clearly and don’t realise this product does not achieve that.

[@raeldor]

Sound deadening and sound BLOCKING are two different things though, right? This blocks the low frequency vibrations coming from the metal, but to block outside noise you still need to put some kind of foam insulator or something on top of this I assume?

[@protouringperformance]

Kilmat isn't just for sound deadening. It's also thermal insulation. I did one box that weighed 17.5lbs and it wasn't very expensive and covered most of what I needed it to.

[@markallendelisle]

Most are using for sound deadening though with no need for insulation (not a race car to worry about excessive heat, A/C or clothing takes care of the rest lol)

[@AmirPomen]

There is closed cell high density thermal insulation foam that are ligtweight yet very good at insulating heat/cold... Thats what u really need to cover whole panel for insulation.. And less bitumen vibration damping matt needed...

[@kjata77]

Even Dynamat has always recommended only 30% coverage to flat surfaces (curved surfaces need 0% coverage). I used to get asked why my sound deadening material applications look sparse & like a monkey applied it on past installs & I'd tell them that I don't like to waste money. 100% coverage only makes sense for SPL shows or to make more $$$ in labor & materials.

If you look at cars from the 60's this is exactly what they did.

[@RajunCajun1]

Have you added tow subwoofers to your vehicle that can handle 800 watts each and only did the 25% sound deadening method? Does it work?(NOT being sarcastic)

[@markallendelisle]

Yup same effect. It’s removing the resonance from the panels therefore I’d say 120-150db you would not gain anything doing more than 25% per panel coverage.
