Hi all!
About a year ago, my parents decided to build a new home. As a retirement gift for my father, I decided I would design a dedicated music room for him. And thus I gingerly dipped my foot into the rabbit hole of acoustics and promptly fell into the infinite void.
A year later, the house is almost complete, the music room is constructed. I present you with (drum roll please):
So yeah, it's a work in progress. Don't worry about the drywall on the ceiling - that was a mistake by the constructor and it will get torn down.
I have however, come up with a finalised treatment plan, which I present below:
All of this is subject to the listening position and speaker position ending up more-or-less where I expect them to. I'll go in to the untreated room once it's finished, set up a speaker, and try to find the optimal listening position. If that turns out to be somewhere very different than the diagrams above, I'll come up with a new plan of attack. I decided to follow @kemmler3D 's advice, and soundproof as much as is reasonable (That's the -7cm numbers you see - 7cm of soundproofing will be put on certain walls).
The end result should look like:
Some notes: Ignore the quadratic diffusers - the design/rendering software I used doesn't have binary diffusers, which is what I'll be using. Also ignore the side-boards of the diffusers - the frame there should be open to allow absorption from a side angle, with just fabric covering it. The front, back, and side walls all have 20cm of porous absorption (rock or mineral wool with 6000-10000 Flow resistivity (Pa.s/m2)), with a 20cm air gap behind. The entire walls will be covered in fabric, leading to something that I hope will look almost as good as the renders. The front door, the wall opposite it, the window, and the wall opposite that, will be the only parts of the room that remain untreated. Even though the rear wall is entirely treated, there's room left in the back there to add some membrane traps (probably purchased from GIK), if they're necessary once final measurements are done. Finally, I've tentatively placed the subwoofer dead-centre between the two speakers, and at equal distance to the listening position. From what I've heard, you don't tell the subwoofer where it goes - it tells you where it goes. I'll try to keep it somewhere near the front wall, maintaining if possible, the same distance as the speakers, but at the end of the day, I'll put it where it wants to go (I pray it's happy there though, as I have 40cm of treatment directly behind it, begging to be used).
So now is the time where I humbly petition you all: please spare me some time, share your expertise with me (free of charge
), and let me know what's wrong, what could be improved, alternative treatment strategies, etc. The point of no return is fast approaching. In a couple of weeks the doors and floor will be installed, at which point I will start the first set of untreated room measurements. Shortly after and with the constructor's help, I'll install the treatment right into the walls, at which point nothing can be changed without vast expense (i.e. my dad's stuck with it). I will of course, be sharing information, pictures, and measurements with you all, in the hopes that it is of value to someone.
Thank you all
