When you're trying to mitigate sound from an ASIC you need a) to reflect sounds back into the box and b) absorb sounds within the box. I've contructed a box from 25 mm MDF and lined it with 30 mm closed-cell foam marketed for vehicle sound-deadening but I'd like to do a better job and I was wondering what else I could construct the box from that would improve performance. I've read that bathroom tiles are good at reflecting sounds because they're hard and very smooth (not the textured ones, obviously) so I was considering attaching them to the inside of the box between the MDF and the foam to improve sound absorption. Does anyone think this makes sense or is a waste of time?

I'd actually really like to make something from concrete like this but it would be really heavy (kind of why I think it would be effective).

you want this from home depot

1)go mdf
2)then the foam you have
3)then the home depot product
4)then the amazon blanket

 to prevent shorts and fires even more use the large fire proof blanket from amazon.


also realize  you need to let air in and air out of that box.

2x  6 foot tubes out  or 3x 4 foot tubes out

2x  6 foot tubes in  or 3x 4 foot tubes in

it is 25 feet long.

I think your construct could be improved by adding ducts to the outlet so the heat isn't getting trapped inside the construct. Some of it will be recirculating. (I only watched the last video).

I'm aware that air needs to get in and out of the box. Anyone who puts their ASIC in a seal box is dumbass!

MDF isn't that good; it's just easy to work with and better than nothing.

I'll look into using a fireblanket inside the box though. Thanks.

yeah  they are short proof and very fire resistant.  they will melt at about 1100 f  but they never burn.

Yeah  that  was a fast  build  it  worked but I ended up putting 3 of these fans on the exhaust end

this helped get all  hot air out and did not add to the noise.

mdf is actually  really good for sound control.

I built  a few recording studios  with

 sheetrock/aspahlt/mdf/asphalt/mdf/mixed foam/fireblankets 

the rooms are very dead
