yes, and there is something about "golden ratios" (which have been discussed in the not to distant past,) that tend to change sound-- echo reverate in a special way.. so churchs tend to use them-- Classic design for churches almost always involves a series of rectangles that each have a golden ratio.. the result is, churches have a special "sound". that, plus the fact that most churches have high ceilings.
St John the Divine cathederal in NY had an exhibit on sacred spaces-- there are several different shapes that have special effects on sound. in domes, ie, you have the ability to face a dome wall, speak to the wall, and have someone on the oposite side of the dome hear you, but not someone in the general space.
so, good planning, results in creating spaces that have a special sound, which results in a specific reactions.
many formal public building use the same technics as churches, for some of the same reasons.
