Acoustic panel questions

BTW, have you got the formula for a Hemholtz to purge a 52hz resonance in my vocal booth.
 
Very funny! You're bullying me. ;_;

I haven't even started building any of my panels yet. I need more wood.

I don't even know jack about how to care of this 120 Hz null in my room, less build a Helmholtz resonator.

funny? and bullying you?? whf are you talking about. YOU are the one that said you almost have IT figured out. Give me a fucking break. :rolleyes: Now that I think about it, you are clue less.

What the hell does my age have to do with it? Is there some magical age where words take on a different meaning? :confused: :rolleyes:
 
Moving on... I have a problem with mounting my panels. They're pretty heavy and my walls are made of gypsum... wouldn't the weight of the panels eventually crumble the walls? The partition boards are very fragile...

Any ideas, anyone?
 
Usually the same kind of mounting that you would use for a picture frame is OK for a bass trap. If you are using really thick/heavy wood for the frame then you might need heavy duty picture hanging hardware, but to be clear the only thing you need a frame for on panels is to give them a crisp edge.

As for Superchunks I am not a big fan of them. The problem is that they are an inefficient use of the money you are spending on fiberglass or rockwool. You are using an ENTIRE BALE of rockwool all in one corner, getting yourself no absorbtion on the opposite diagonal and none to control slap echoes on the parallel walls.

You could take the same bale as you used to build the superchunk and make four four-inch panels for the corners and four two inch panels for the parallel walls and/or clouds (or some other combination appropriate to the room accoustics). There are very few rooms that could not be tamed with one bale of 703 fiberglass inteligently placed. Putting the entire bale into one corner is not inteligently placed.

I believe there are those that would disagree with you, although, I'm certainly no expert. But as far as modal traps are concerned, tests have confirmed their effeciency at what they are intended for in contrast to single panels across a corner or placed elsewhere. Afterall, room modes terminate in corners. And that is the point of BASS traps. To tame room mode frequencies.
 
Agreed Rick. That's the most opportune place to put things. However, there are other times where purely axial modal issues respond better to treatment flat on a surface in relation to the head position - like on the middle of the rear wall of a room to kill the null off that wall based on the distance from head to wall and speakers to wall.

Assuming by "partion boards" you are referring to wall studs? If so, they should support the panels. I would take a finishing nail and hammer it into the gypsum board to locate the studs, and attach panels to the studs via screws and wire placed horizontally across the panels, as mentioned earlier, just like a picture frame. Let them carry the weight, not the gypsum board. If that is not an option, hanging support from the ceiling rafters or joists or building a stand may be options to look into.
