For AC, I have found wall-hanging units that go as low as 22db.
That space is probably too small for a vocal booth--at least one that is comfortable to be in, since once I treat it with acoustic panels you'd be brushing up against them all the time.
So now I have some new questions:
6) What is the best way to add soundproofing to the existing construction (which is all concrete)? Is adding another layer of concrete wall the best way to go? Or should I do the wooden frames with glassfiber panels between them thing? When doing either, should I be leaving an air space of a couple of inches from the original walls?
7) For the floor, I have seen conflicting views. In Jeff Cooper's book, he has diagrams of wood floating floor, but in Rod's book, he says that it's a bad idea to do floating wood floors and strongly discourages it. Who is right?
For my situation, my studio is on the 2nd floor of our apartment (it's a 2-story loft apartment in a high rise. We have other units below and above us. We're technically the 7th and 8th floor. My wife isn't concerned about any sounds I make upstairs while she's downstairs. She's never complained about my music in the 5+ years we've been married. So, I'm not as concerend about the floor isolation in terms of bothering others, and my wife is prett quiet in general, so I can't imagine her making enough noise downstairs to travel up from the ceiling into the studio. Or am I wrong? Should I bother with soundproofing for the floor, or just add a wooden floor on top of the concrete and call it the day?
8 ) All those support beams you see on the ceiling and at some places in the walls--how do people generally treat those? Just ignore them? Treat them like any other corner and put bass traps around them? Since I need to build an inner layer of soundproofing walls/ceiling/floor anyway, maybe I should just make the soundproofing walls flush with the beams so they no longer protrude?
9) Should I just build a soundproofing door for the storage space and treat the room as if that storage space does not exist, or I should turn that storage space into a giant bass trap? If I do, would it throw off the symmetry of the room?
10) For isolation and absorbtion, as I understand it, you can use cheaper material as long as it has similar density to the often mentioned glassfiber stuff (703, 705). So what are these cheaper materials? It also seems that rigid glassfiber panels are preferred because they hold their shape better when making soundproofing walls and acoustic panels. Is that the only reason? |
6) Best would be adding additional walls with a small space to the existing ones, the „real“ room-in-room concept.
7) If you can afford it do a floating floor with insulation between the wooden bars. Have a look also on johnlsayers.com. For me as I have my studio in the basement and enough mass for the floor I first put in rubber matts 0.5mm I still had and put OSB wooden plates on it. This seem to work well. Have a look also on my thread here in the studio construction subforum:
Had to move - studio rebuild in basement
8) Use them to make a ceiling non-parallel to the floor, so you avoid standing waves.
9) You could use it for bass trapping but first you should measure the untreated room, if the reverb is about 2.6s with linear frequency response you are fine. A storage is also fine to have…
10) There are also isolations made of cannabis… they could be cheaper. Or use basotect which is a bit more expensive…
P.S. sorry for long time not answering...
