Traps on walls vs standing floors, any diff. acoustically?

[jim1961]

Bass traps in corners really need to "seal" into the corners, not a few inches away. And yes, corners is where most people treat first for bass trapping.

I would ditch the mattress for as you pointed out, it really only "traps" high and mid frequencies.

thanks for that jim, i've made em closer into the corners now & took off the mattress.
But what about the walls? and again, should it be neccesarily be 'Hanged' on the wall or Standing on floors, a few inches off the wall will also have same effect(the other ones)?

Your not going to trap much bass on walls. If you need help with specular reflections, yes, some absorption panels might be good. Thickness, airgaps, and material all depend on how deep you are willing to go.

Just be vary of making it too dead. Might look into diffusers if that becomes the case.

Many of us have to or want to treat rooms temporarily. On the floor is better for bass traps. Obviously side reflection traps need to cover the side reflections so raise as necessary. Gaps behind, even by leaning, add performance.

I would guess the trap behind the desk is not doing much. I would put that in a back corner or wall, or overhead as a cloud if you can manage four holes in the ceiling.

Thanks a lot Jim & Dan.
As Dan suggested i moved the trap on front wall & put it against the rear corner, in a way adding to the depth of both traps. Now both the front right & rear right corners have 2 traps each so effective depth is 8" there (4"+4") & it has drastically improved the bass response, much more tighter now. Now the front wall is naked & rear one has one trap.
The imaging & soundstage is still not well right now. I tried experimenting by adding one more trap on both sides, thereby increasing the wall area covered on side reflection points. that did bring about much reverb & dynamics detail and improved imaging as well, but as i have limited traps, i had to put em up in the corners as bass issue had greater priority. Also, right side of me is a big window, is that making a symmetrical problem. I've hung some curtains there but donno if its doing any improvement to the sound.
So what can i do/add to be able to hear the reverb times & dynamics more accurately/in detail.

I am guessing hard floor and hard ceiling. Cloud traps require only a few small holes, but if the Landlord is not OK with that, thick rugs on the floor between you and the speakers.
Use the mirror trick to create a Zone Without Reflections between you and the speakers. The increased clarity will help you hear 'into' the recordings.
Obviously the situation is limited but if you have the energy and money traps can be installed on stands. EQ is worth a shot. Dirac Live or AudioLense have come to my attention in a good way. Headphones are the ultimate freedom from rooms.

Yeah, i just tried a rug on floor, but it seems to affect only the very high freqs.(above 4/5k), maybe coz its not as thick? but most rugs aren't so thick anyways, maybe a few more mm thick, but those thicker ones r really expensive here (twice the cost of a bass trap)
Traps on stands are better than direct standing? what material do i make stands with?
About those room correction softwares, wud they work well with any mic, coz i don't have a measurement mic, just a shure sm58.
