well, one of the best diffusers is a bookshelf full of books. they
are never the same size, depth, density, or anything. if you have to
deal with a room that has things which are undesirable, such as being
in a box or rectangular shape, or with curved walls (aieee), then....
well... if you have language labs, maybe you have tons of leftover
reference books, or can get them from the library when they weed.
it's no great science, but books are amazing diffusers. it's
diffusion you want more than absorption (assuming the room is not
*too* reflective). the diffusion will enhance sound, speech
intelligibility, frequency response, everything. if you don't like
the looks of the books, and if they're not interesting, you can cover
them with fabric. this *can* be aesthetically pleasing if you've an
eye for cloth and the like. the bookshelves should be fairly high
too, at least covering 2/3 of the wall, certainly higher than the
average adult, and filled completely with differing sizes of books.
that's a cheap way out of a bad room if you can't change the wall
