(I posted this in the Sound-Design section but got advised to post here instead).
I just purchased a 3d printer and I am working on a product with a box that has a hole in the bottom and the top. Inside this box I have a few electronics that has a pretty loud sound. What I now look to do is to kill that sound as much as possible so it is not possible to hear it as loud.
At home I have a few acoustic panels looking like this and as they are very lightweight it seems like a very good solution for this design: EQ Acoustics Classic Wedge 30 Tile grey
If I cover the interior of the box on all the walls would this make the sound not leave the box as much which would result in a lower sound? I am very novice when it comes to this area so any help/tips is very appreciated!
