Hi all.
I have a small studio-tracking room 6.5 metres by 4.5 metres, control room 6.5 metres by 3.5 metres.
I need to build end wall in end of control room, and am going to build it out of hebble blocks (aerated concrete). This material is like aero chocolate-easy to cut with diamond circular saw, but is fiddly to work with.
Came to me that where the 2 blocks join, I will cut various widths off the join of both blocks to get a gap (neck). Then as the neck moves into the 2 blocks, some 2 cm in I will cut out cavities of various dimensions (in rectangles/squares)in effect fabricating helmholtz resonators. Because the sizes will vary the frequency absorption will vary as well.
I then intend painting the whole hebble wall surface, but leaving the neck and cavities unpainted. Hebble block is incredibly absorbent, so the question is whether there will be much resonance. However, I think that the cavities will be useful to absorb sizeable sabin counts across the frequency spectrum.
Does anybody have any acoustic theory that would indicate this is a waste of time, or worse, be counter productive to sabin absorption/creation of diffuse resonance? Has anyone thought of this, done this before?
Much appreciated
