Comment on [HELP] Sound proofing and cooling server cabinet
ArmoredGoat@feddit.de 1 year agoThanks for your great advice! I did a quick measurement of the noise spectrum inside the cabinet with my phone:
It seems most of the noise is in the 100 - 1k Hz range.
Basotect looks perfect! It is also quite affordable. Will 3 cm will suffice or would you recommend thicker padding?
(If I can’t find a proper solution for the cable ducts, I could use any remaining Basotect, glue it together and fill the duct with it. There will be just a few cables that have to leave the cabinet anyway…)

Why did you measure inside the cabinet? Don’t you want to dampen the perceived noise outside of the cabinet?
Physically speaking, 3 cm will absorb all frequencies above 12000 Hz, and dampen everything beneath at least a bit, ignoring the absorption capatbilities of the material. I’m no expert in the field of material sciences, I just know by word and experience (insert “trust me bro” here) that its absortion capabilities are really good.
It will lessen the perceived sound by a measure, but do not believe, that all sound will be gone. But a 3 cm-thick paddening all around will to a good job.
Think twice about glueing. Glue is nasty to remove, maybe just push cut-to-size pieces inside of the ducts to make them fit? You could make ones, which you make snug around the cables leaving the cabinet?
