Mass Loaded Vinyl Soundproofing – What Weight Do I Need to Block Out Noise?

Our Noise Grabber™ MLV Mass Loaded Vinyl sound barrier solutions are available in several different weights or thicknesses. In this video we demonstrate the sound and noise blocking capabilities of each MLV weight.

A lot of people speak about soundproofing on YouTube but not many show test like this! Thank you for that.

The reason why there's little difference between some of the different widths is that the measuring device is placed on the table, near the opening or gap so it's going to be fairly similar from box to box to box since they all have similar gaps when laying on that surface with only gravity to create a seal. Would have been better to place the measuring device above the box so that the sound escaping through the bottom gap is not the primary sound being measured.

Just a heads up this is very useful material to block sound. One thing he didn’t quite do right and what really helps even more so than his test is that it needs to be air tight. That horn was still leaking from the bottom.

If you seal this you’ll get even more reduced decibels than his test. If you have any air leakage then that’s sound leakage and that definitely makes it easier for it to escape.

20 decibels is definitely great improvement, just remember decibels isn’t a linear measurement.

Good to finally see an actual video by a soundproofer.

Thank you for this! This video is freaking brilliant. Proof it works and the video isn’t 20 minutes long!!!!

You’re my hero.

You should really redo the 2 lb because it was 2 db's higher than your 1.5 lb? Could I just wrap this around my in ceiling speaker boxes? Still in new construction stage of home theatre.

Never have I had to adjust the volume so many times in a video. Jesus Christ

Thank you for this! Great to see the product tested in real time and clearly not set up to give unrealistic expectations. MLV was my go to when I used to build recording studios, especially on the floors.
Some sounds you just can't stop unless your willing to put 2 feet of air tight concrete around you, an air horn is certainly one of them 😂

You sir are a genius!! I love how you showed the differences enough that ai subscribed and liked you video!

You have my respect! Great job!!

I will share this!!

[charliefoster]

I like this test and this guy. I really like that grin he has after he puts the box over the speaker, so proud of himself LOL

[lucistheband]

This is fantastic and great! No difference however between the 1.5 and 2 lb. This is going to help me with my decision on how to soundproof my new condo music room!!

[genehodsdon]

Thanks so much for doing this!!! I’d be curious the effects on lower frequencies

[annavariumful]

Thank you for a VERY easy to understand compassion. I think you would have had even better results if the base pad was larger / flatter so all the various boxes were equally sealed at their base.

Good thing I have my computer sound drivers configured to normalize sound (making loud noises quieter and quiet noises louder) so watching this video wasn't too bad on my ears ;)
Condolences to all the people who listened to this on loudspeakers and didn't turn down the volume.

[krisdestruction]

This guy probably killed his hearing long term for us 😂

[johnpadams]

This material is frequency dependant. So what is the frequency band width or better yet, what is the pink noise frequency response curve of the reduction. That’s what really matters. Low frequency will not be reduced very much.

[functionalvanconversion]

Amazing demonstration! Makes it easy to see the difference. Will reach out on the next remodel:)

[cheinei]

Thank you!!!
You can hear everything in my apartment living room like the door is wide open. Its horrible.
Im running to homedepot asap. Thanks again!

[Dave-dhrt]

Love how hes smiling because he knows their product is good

[RockerProf]

Did you happen to do a before-and-after decibel test for each of those different weights? Thank you for this
