I am a 19 year old song writer/pianist/bassist who has been recording in a suburb outside of boston for 4+ years. 3 years ago I built 5 bass traps via ethan winers web site in my 40x30 live room, and we mixed in a concrete 15x15 box covered in the corners and all the direct reflecting spots with OC-703 rigid fiberglass. We had a budget at that point considering our age and lack of time for work aside from high school. Because of our location we had no need for isolation aside from the concrete mixing box (which i now understand is a terrible location for mixing)
I am going to Berklee next year and moving into the bottom apartment in a three story Building in Brighton. Unfortunately I believe the building lays on the end of two identical connected Apartment complexes owned by different landlords. The place is a spacious 3 bedroom with a huge living room and kitchen. I don't know the dimensions yet. The drummer is moving in with me and would like to be able to practice at reasonable hours. I'm sure that playing during the day will be fine with the neighbors but I would like to tone down on as much of the noise as possible. Luckily the walls of his room only touch other walls in our apartment or the outside of the building. So basically we have no side neighbors. We are thinking about converting his room into a fo-drum booth. Obviously its not a real booth because we can't do anything permanent like double the drywall or build a room with in a room. We do have a decent amount of money to spend though.
I'm no genius when it comes to acoustics but I believe that the most cost effective solution would be to try to get rid of most of the low frequencies via bass traps. I figure if I build a riser for the drums that is just a 5x6x1 sealed reverberating box and place 3" 703 about half way between the top and bottom that should do a decent amount. Essentially it would be a huge bass trap for him to play on. The box would be raised above the floor with rubber feet. I will also be sealing the back to the 5 bass traps I have and placing them in back of this drum riser a few inches away from the back wall in his room. My third Idea is to hang 3" 703 about half a foot from the ceiling. I believe the room is a 15x20 and I know that the drummer will be willing to give up at least half of it for sound absorption My question is, could anyone suggest a better method for this? Do I need the drum riser or is it kind of useless with the other traps and the dropped ceiling? Does someone have a completely different idea that may work better? Am I being a complete idiot?
Since I do not live there yet I do not have any further information about the place. I just would like to start building soon while I still have a place to do it.
