small room treatment questions
Posted: Tue Mar 19, 2019 4:32 am
Hi everybody!
This is my first post and this is also my first attempt at doing some acoustic treatment.
I have been reading this forum for a while now and I really think it is a great source of information!
I am planning to treat a bedroom in my house (3.67meters long * 2.99 meters wide*2.47 meters high) in order to do some mixing at home.
The room is in a quiet part of the house, where I do not disturb anyone (tested and approved!) and there is no neighborhood around, so it is not soundproof at all, and does not need to be.
I know the room is small, so I do not expect it to be perfect, but I still would like it to be decent.
Here is what the room looks like :
As you can see the window is not centered, and the door is in a corner.
I didn't manage to upload my mdat rew file to show you my empty room measurements, so here is some REW screenshots of the empty room :
I'm planning to work on the rear wall of the room first.
I want to take advantage of the rear space next to the door, which is 60cm deep to do some bass trapping.
So I thought it would be a good idea to build some hangers in this space as a broadband bass trap.
I would also like to build a superchunk style bass trap in the space above the door.
Here is what it would look like :
The hangers would be made of 10mm "isorel mou", the french equivalent of homosote (slightly denser than homosote but in the same ballpark), and 45mm glasswool with a density of 12kg/m3 and an air flow resistivity of 4kPa.s/m². There would be 5 hangers of 75cm deep by 240cm high, 1 hanger of 68 cm deep, 1 hanger of 46cm deep and 1 hanger of 37cm deep. The walls around the hangers would also be covered by 45mm of the same glasswool.
The superchunk would be made of glasswool with a density of 12kg/m3 and an air flow resistivity of 4kPa.s/m².
My questions are :
Should I start treating this room with the rear wall?
Does this design make sense?
I know that the orientation of the hangers is meant to change in the middle of the width of the room, but the door won't allow me to do so. Do you think it would still be effective like that?
Is there some more effective way to treat this space?
Do you think this specific glasswool is a good choice for both the hangers and the superchunk?
Should I cover the superchunk above the door with a thin plastic film to avoid killing the high-end frequencies from the start or should I wait to do some measurements and adjust from there?
Thanks in advance, regards from France,
Geoffroy
