Comparing a bunch of different sound dampening materials because I’m bored.
While I didn’t include this in the video, I chose to go with MLV and Poron in the case and PE foam on top of the PCB for sound dampening. It’s got a nice marbly thock sound going on :eyes:

Notes :
Poron - Definitely still has a hollow sound since it’s a pretty thin material. Would recommend putting some other dampener underneath to fill the space.
Shelf Liner - It’s perforated grid design makes it so easy to cut out holes for any type of case. Also rather thin, so it’s best to use in combination with another dampening material.
Yoga Mat - I’ve used this before on a previous project and thought it was a great option for sound dampening. It’s pretty thick, so it will be compressed quite a bit in the case. However, still noticed some reverbrance despite its thickness.
Neoprene - Only used 1 layer with another small piece underneath in the test. Really thin piece of foam, so I would recommend 2 or more layers in a case with a lot of space.
Silicone - I made this to fit exactly in the Tofu60 case, however, a lot of prep was needed beforehand. Needed to clean the case, seal the case of any holes, apply a mold-release for easy removal, scale to get the correct measuring ratios, and a level to have the case perfectly flat. Then waited a full day for it to dry.
Sorbothane - Super solid dampener overall. Price ain’t so bad and it absorbs a lot of the reverbrance quite well.
Noico - Literally the stuff they use to dampen sound in cars. Made the board sound deeper, giving it more of a ‘thacky’ kind-of sound profile.
MLV - Mass Loaded Vinyl. It’s a very dense material that’s effective at absorbing sound, however, it is a very expensive option. BUT IT MAKES IT THOCK AF :OOOO
Rockwool - My bad for the squeaky gloves. Shit was MESSY AF. You know, I gotta add at least one bizarre material to this video. While it’s strange, insanely messy, and tears at the slightest touch, it is, however, an actual material used in studios because it’s really effective at absorbing sound. Only difference from mine is, I’m using Rockwool cubes which are intended for Hydroponics while audio engineers would use something like Rockwool Panels. They're both still Rockwool, so I thought it would be okay. Which I instantly regret after pulling it out of the box. It was impossible to cut it down from 25mm to 2mm without the material completely tearing apart. In hindsight, it’s probably better to just rip the Rockwool into small pieces and fill the case from there, but it just makes a super mess so...
