I am currently building a box filled with electronics and I now look to isolate the sound a bit with the lightest and best material out there.
What I am looking for is a thin, lightweight and very soundproof material. I came across a material called Sortbothane and it seems like a very good fit.
Sorbothane Acoustic & Vibration Damping Film 40 Duro
0.04" of Sorbothane Will Absorb up to 4 dB
That number is pretty impressive I must say and the material seems to be reasonable light and thin as well.
Goto JINBIAO to know more.
So to my question, do you think Sortobothane is the way to go or is there any other materials out there with the same/better soundabsorbing?
I am also thinking to combine a few materials to make it very solid. For instance I am planning to use a small layer of silicone as well.
$\begingroup$Isolate and absorb are two different things:
When used in the proper geometric configuration, a thin layer of Sorbothane could work well for either of these applications. Its just important to approach your problem with an intent. It will be best used at the interface between two masses, like the enclosure and the mounting location or the door of the enclosure and the enclosure, etc. Selecting this interface, and changing the amount of mass can direct toward isolating or absorbing the concerned frequency. This will take some math and/or some experimentation. Other means of attachment across this interface like bolts, screws, adhesives, etc will influence how well the absorbs/isolates behaves.
Lower-energy and higher frequency sounds that are already airborne (like a buzzing electronic component) may be better absorbed with open celled acoustic foam inside the enclosure.
