I mean, I am into the process of constructing my studio out of an old (small) staple (staples ?).
These DIY stuff are exactly what I need nad I try to find as much as I can to help design my future "homeplace" as I'd like it to be.
Although there tons of question, I'd like to know two things
1) How choose the fabric to cover the whole trap ? These explanations don't tell that much Sometimes it is said that it must be acoustically neutral. How can one know ?
2) Can one really get sufficient bass traping only with rock wool, without invloving some barrier mat kind of material ?
1) if you can easily breathe through it when stretched tight across your mouth... it's a fair bet.... the most commonly used in the Uk and europe is probably Interface fabrics " Cara"
2) yes, no, maybe... entirely dependent on room size and geometry , and required results... I typically combine Limp mass, broadband absorption, Perforated surface, and damped membrane designs. But I have done rooms with only broadband when necessary.... I do try not to go for highly tuned devices unless they're absolutely necessary....
