What material is the best for soundproofing?

Way to get right to the point! On behalf of everyone whose time you did not waste… 👏much appreciated.

Cool vid but it would be even better if you could run a slow 20hz-20khz sweep to see how they cope at different frequencies

There are basically two ways to increase sound insertion loss, increase the areal density or have multiple mediums. The sound has to excite the barrier material to transit through it. The denser it is, the more energy needed to excite the molecules. There is also an energy loss as sound transitions through two dissimilar materials. There are a few other ways, but they are not as common or significant.

Thanks for the test. It would be great to see you add double layer drywall (both 1/2" and 5/8") and double layer drywall plus green glue to this test.

I have spent hours upon hours of researching online about soundproofing for building my portable at home studio. This by far has been the absolute hands-down, most helpful video I have ever found. Thank you!!!

Everyone, who wants to build a soundproof server cabinet is glad for this video. Thank you!

So simple an experiment, and yet so useful. Thanks 🙏

Great video!! I’m making a vacuum cart/box today. Going with plywood and Sheetrock inner wall.

We always used MiCORE for sound proofing either directly on drywall or attached to 1/4 mdf on top of dry wall. Thats been several years ago.

I spent way too many hours thinking about the noise my NAS is making; this video was a Godsend. Well done.

this is so helpful for me. im in very tight budget to get things wrong. you save me a lot. God bless you sir

Sound attenuation depends on the mass and the completeness of the barrier. In other words, the heavier the sheet, the less the sound that gets through -so long as there aren't any gaps. Your best performing option had two barriers with the outer one having reasonable mass. One thing to be careful with is what the soundproofing is trying to achieve. Some soundproofing measures are designed to reduce noise inside the 'chamber' by absorbing the sound and stopping it from reflecting back. That's where some paints work best, and definitely the foam. Loved the no-nonsense practical demonstration though!

This is the only useful video about this i have seen, and it didn't appear in search results, it just showed up in my recommendations.

Nice test! In recording studios, the ideal concept of isolation comes from "floating chambers" I think that concept will help you.

Very useful experiment. Thanks for sharing!

Thanks for the tests 👍

Sonopan needs acoustic sealant. Also, it should be combined with 5/8 drywall. Just used this combo on my home recording studio build and it worked really well.

awesome! thank you posting doing this and posting it here.

Sweet and useful experiment. Thank you.

Cool! I'm a big fan of Rockwool/Roxul too!
