Will this work to trap bass

Wholyroly · 21st April 2007, 12:15 AM

I've finished my Broadband absorbers and am trying to absorb some base, I came up with this micky mouse Idea and am just wondering if it will work, thx Roly.

I've taken Rockwool and cut it up into manageable chunks and put into old plastic grocery bags.

Next, I tacked 1x2's to the wall and ceiling in my room to create a corner soffet, tacked on plastic to reflect the mids and highs, tacked on some material left over from my BB absorbers and then stuffed the soffet with the bags of rockwool, Pics below for further explanation. thx for any help!!!

That's fine, but understand that with bass trapping, you need as much as possible. So it's fine to use small baggies full of fuzzy stuff, but you need a lot of them to do a good job.

HGTV would have a heart attack if they saw that

I will be putting up quit a bit more Ethan, Ive read your informative easy to read tutorial (thx for that). I have about 40 square metres along that edge. After putting up the 7 BB absorbers that I built there was a large improvement in treble string clarity when playing my acoustic. Im guessing in a small room like mine as many bass traps as possible will be essential in taming those freq's. thx for chiming in, Roly

LOL Good call, I've have nothing now if I can't laugh at my inept carpentry skills. I will improve upon this when I see some results. This room is my guinea pig and I will be building a proper setup at my house. thx Roly

I thought that whatever material you used to contain the absorming material needed to brathe to properly absorb and dissipate the air driven buy the waves.

Also, what is the main advantage to putting the stuff into the plastic bags? Why not just shove the raw material in there?

From what I understand bass frequencies will go through anything and mid to high will reflect off of plastic. My focus in this small room was to let the bass freq's be absorbed while reflecting any mids and highs?

I put them into plastic bags because it was easier to manage cleanly for me rather than stuffing raw chunks of insulation, but, since I have a plastic barrier under the cloth I'm not sure it was necessary, but, whatever, easier to clean up if I have to take it down (rental). I have 7 BB absorbers that I built as well, just testing out the waters at this time.

I hear ya on the cleaning up part!

As I do agree with Ethan that it probably will work, but I would take the time to test the room to make sure. What you have done seems to me to be pretty random, and like anything else could give you a random result.

But hey, 2

s up for thinking out side the box.

lol, thx Glenn, I haven't actually set up the BB absorbers yet, I just dont have any place to store them at the moment so they are leaning against the wall, everything else in my room is now in the living room of our 2 bedroom duplex (I dont have a bedroom anymore

but will eventually have a recording space

) The bass trap on the wall is just one of many I will be putting up. If I understand things correctly the more bass traps you have the more "clean" bass you will get. I will then test the room to pace the BB absorbers correctly. Pls advise if I am out to lunch, still re-reading up. Thx, Roly

The thing with bass control is thickness. The thicker you can get, the better it will work down deeper. Get as much up in there as you can. Leave the bags so you can get the air out of them and get the whole space filled.

I'm wondering about the air gaps between the bags. I would think it isn't a huge deal since most of it will be sucked up by the bags of wool, but if there IS a problem with air gaps causing bad standing waves it would be good to know now before you complete the project so you can pack them in even more tightly. I mean, this will definitely work to some degree, but if it's going to work great then might as well do it right the first time.

Anyone have any thoughts about that?
