Hey everyone, new forum member here. So I'm researching on how to improve the acoustics of a spare room in my house, and ended up over on realtraps.com where I read an article by Ethan. Since my budget, time and resources are pretty limited, this part of the article caught my eye: "The cheapest bass traps you can buy are 4-foot bales of fluffy fiberglass, left in their plastic wrapper, and stacked in the room corners."This got me thinking if something like these would be consistent with what Ethan said here, and with the general properties of bass traps: www.homedepot.ca/product/owens-corning-ecotouch-multi-purpose-pink-fiberglas-insulation-for-small-projects-2-inch-x-16-inch-x-48-inch/1000539142(from my experience you might have to paste this link in a new tab for it to work) The reason I ask is because these particular packages of fibreglass seem to be a bit smaller than what was typically discussed on forums, by people who were also interested in this cheap approach. (Also because I can get a discount on these ones, as my brother works for homedepot haha.) So I just wanted to make sure these aren't too small/thin and the specs all check out. I'd stack them in the corners like Ethan mentioned. Specs: Packaged Depth: (in inches) 6 Packaged Height: (in inches) 16.5 Packaged Weight: (In lbs) 0.4 Packaged Width: (in inches) 6 Faced or Unfaced: Unfaced Product Length (ft.) 4 Roll or Batt: Batt Thank you in advance and have a great day!

In short, you need area, volume and coverage to make a difference. That package size 6" x 6" x 16.5" is smaller than a pillow. If you had 50 to 100 of them it would do something but you would be much better off following Ethan's suggestions for corner bass traps and RFZ absorbers placed strategically.
The idea of using bales of fiberglass is the cheapest mostly because there is no labor in manufacturing purpose built panels and installing them on walls ceilings etc. The fiberglass in bales is compressed and if allowed to expand after unpackaged and installed in traps and soffits etc. will probably be more effective and cover a greater area and volume.
I'm sure someone might possibly find shortcuts to acoustic treatments but the results of well designed applications will certainly be superior.
Please search this forum (and others) and read about other member's acoustic treatment situations. You might find that the answers are generally are very similar and basically the same: Coverage, volume and placement.
