Acoustic treatment


I want to build my own bass traps and was wondering if there are any other alternatives to fiberglass and rokwool. Foam is not a consideration as I don't believe it has the necessary qualities for absorption. I have heard of cotton batting, does anyone have experience with this material. The idea of fiberglass makes me itch just thinking about it, but I'm resigned to using it or rokwool if that's all I have.  Please make suggestions and let me know your experiences.

Thanks

Geoffkait, just throw the CD's away and download all your music in MP3 files. That should be perfect for you. Your ear works just like any other microphone. It detects minute changes in pressure. In your case you might want to clean the wax out first. In the office we use a waterpick for that. 1 part hot water to 1 part  peroxide. Careful not to squirt your eye:)
Ya don’t get what I’m saying here. Look, it’s not rocket science. All you have to do, gentle readers, is compare the cassette version of almost any record with the CD version. Or the LP version. All will become clear.
@theaudiotweak , are the synergistic research acoustic art (bowls) similar to what you are talking about?  I experienced these firsthand and they definitely worked.  Crazy stuff...

@noble100 , do sba work better in treated rooms?
@noble100, Correction, does a DBA system, or a SBA too, sound better in a treated room compared to an untreated room?

And... what is a DBA?

Hello b_limo,

     DBA is an initialism for distributed bass array.

     My 4-sub DBA system is in an untreated room and functions very well.  I can't imagine how any bass room treatments would be beneficial.  The DBA concept works best when bass soundwaves are allowed to freely reflect off room boundaries, I think any room bass treatments that would impede these bass soundwave reflections likely would also impede the effectiveness of the DBA system.

     Sorry, I don't know what an SBA is.
