are those RPG diffractals (QRDs) on the front wall? i'd love to see the rear wall :)

curious to hear more! could you detail what the ideal "size" of the rug should be? what about thickness? have you taken into account incident angle? ---since a floor rug will most certainly not have...
can you at least make the effort to read and understand what ive said instead of presenting ridiculous commentary which is meant to distract others from the fact that you are making comments which...
further outlining issues regarding small acoustical spaces...
and whatever he has on the floor will not combat LF modal issues, period.
well. there is a ridiculous amount of energy content in LF wavelengths.
could you cite a better solution to absorb this content?
pressure based traps (limp membrane, helmholtz, etc) will work...
well, luckily for the frugal engineer -- the most effective material for porous bass traps is also the cheapest! caveat, that you have the real estate to give up in the corners.
expensive OC703...
im still waiting for your response to my previous question...what is a jiffy?
could you quote some posts that seem to insinuate that such solutions require large sums of currency? --where are you getting this impression? be specific.
my local supply sells a box of OC703...
what are these "3D models" and "$6 million rooms" you keep referring to. could you please elaborate?
what is the cut-off for you, $4million rooms? or $2.575million rooms? please clarify so i...
my comment was in humor - could you explain why you assume my comment was of a serious tone?
you do not treat a single corner (front-left corner, as you continue to repeat)...you will need to...
whatever material can perform broadband absorption will work. for taming early specular reflections, place it at first-order reflections (side walls, ceiling, etc) foam wedges wont do anything for...
it's your money. if you dont want to take the time to understand your issues, and thus choose 'treatment' that is most effective to solve your issues (and place in an area where the treatment is most...
the depth of the corner porous broadband bass trap will determine the density of insulation to use (actually, the gas-flow-resistivity). so if you cannot give up much real estate, then you could...
porous absorption is placed into the corners because otherwise the LF wavelengths will just diffract around the absorption. by placing them in the corners, you are forcing LF energy through the...
well, there you have it, folks.
how do you eq yourself out of a null?
i call bs. you cannot distinguish decay times of individual frequencies. i dont think anyone on the planet can. what you're discussing is in no...
good - you need to choose your treatment based on measured problems so you are not wasting money on treatment that is not useful to your situation/rooms issues.
you're likely aware, but just to...
i concur --- ethan has taken the time to write a wonderful article that goes in depth into the issues we face in small acoustical spaces, and the best way to "treat" those issues. regarding foam,...
what??? RF is much easier to absorb than LF content (which has a hell of a lot more energy present). what on earth suggests that a room able to absorb 10khz would not absorb higher frequencies?...
please do not propose such ideas as solution. you are sending the wrong message to people who would otherwise like to take the right approach in treating specific issues in the room. this is the...
waterfall plot (0-300hz; 0-1000ms)
Envelope Time Curve (0-300ms)
the waterfall plot will detail modal issues (frequency response + decay time (modal ringing))
the ETC will detail specular...
right - and how does one know the issues that need to be "tamed" without measurements? how can one verify that the procured treatments are indeed functioning as advertized without post-treatments?
...
all small acoustical spaces will benefit from as much broadband bass trapping as possible. due to the small dimensions, the modes are generally spaced further apart. trapping in the modal region...
sorry, but any chamber that attenuates all reflections is anechoic - regardless of the area of electro-mag spectrum that is of context.
