In Reply to: There is one interesting difference for bookshelves… posted by David Aiken on January 25, 2006 at 13:54:01:
(DA): "One tends to push books back as far as they will go on the shelf. With built-in shelves, that's right up against the wall.
With freestanding shelves it's not as simple. If there is a back to the shelves, the tendency is to push them up against that. If there's no back we always end up with a space between the back of the book and the wall.That space is the difference. Despite what most people say about books as diffusors, I find the largest benefit for me is in absorption and that is affected by surface area. Books that are pushed up hard against the wall or the back of the bookcase have less exposed absorptive surface area than books which aren't, and the difference is audible. My bookcases are freestanding with backs and are placed along my left side wall. I 'fine tune' the absorption at the first reflection point by pulling books forward away from the bookcase back in that area."
Inmate: That's a very interesting insight. Can you provide any acoustical measurements which highlight your points and give some quantitative data about the differences?
