In Everest, F. Alton, and Ken C Pohlmann, Master Handbook of Acoustics (New York: McGraw-Hill, 2009), p. 247, a range of room ratios are listed to achieve optimal modal distributions using the Bolt range and a set of external sources. In other words, this addresses the question: what size should I make my room to achieve the best even distribution of sound throughout?

In order to facilitate these calculations, I have written an open-source program, acousticsize, that will let you calculate room dimensions that fall within the Bolt range using these secondary sources, based on a height input.

So, for example, if you had an internal room height dimension of 2m, you could do:

python ./acousticsize.py 2
