I think I'm going to have to go with either straddles or superchunks in each corner, including the wall to ceiling corners. I'm leaning towards superchunks. I know they are more costly than a straddle type corner trap, but I have a lot of the mineral wool already, and the stuff I am using is easily available to me, so I don't mind the expense.
.Considering my 8' ceilings (which are still considered 'too low' for good drum sounds) should I cover the entire ceiling with mineral wool? If so, should I then cover that with plastic sheeting to recover some of the mids and highs?
Floor is going to remain reflective of course.
My concern is that as a drummer I don't want the room TOO dead. But I also wonder if "totally dead" is the best option for a room as small as mine.
would spending time creating REW files be worthwhile in a live room? or is that more useful for control rooms?
The straddle traps are cheaper, but, the big consideration is they are more effective at absorbing bass. This is because standard fluffy insulation is better at bass absorption than rigid, due to a more optimal GFR. (Gas Flow Resistivity)
Did you order rigid or limp mineral wool batts?
Or use a 1" airspace.
Oh yeah, the wiggly wall. If you like the look then sure. I just worry about unpredictable angles in a small room.
Do you have any links to articles providing more detail about that?
I guess it's technically rigid? I think its more medium density than high density though. the specs are posted above, but I dont know if they tell you what you are looking for?
I had initially planned on having wood slats on all of the walls. I think during my investigation I determined that might not be the best idea.
What are your thoughts? Use them? leave them out entirely? or just use a few, spaced far apart so as to be aesthetically pleasing but not have much affect on the acoustics?
I should have may evidence if im going to make statements like that.
The only firm reference i can surely think of is Rods bass designs in the book often use a rigid front with fluffy.
If you hold it up flat does it maintain is form or flap around.
No worries man. I hope you know I wasn't trying to call you out.
I tried to hit 100db in the drum room, and when I stepped back out side that room, with both doors closed I was getting readings at the noise floor level of the house, which, granted is not great. (about 54db)
UNTIL I hit that 30hz tone. Then I was hitting around 90db in the drum room and 72 right outside the door.
That missing section of the outer leaf near the garage may be the culprit. It might be leaking that frequency.
I meant to comment on how nice the pffft sound was in your vid, when you opened the door. Its a sign they are sealed up well.
Its good to not see any weird peaks at gross frequencies like 4k
If that new wall section doesn't do the trick, it may be worth considering and additional drywall layer if the current isolation isnt acceptable. Especially if the leaves are the same.
But up to 4" of air space increases low frequency attenuation. After 4" theres diminishing returns.
