In Reply to: Raise that ceiling! posted by genungo on June 14, 2015 at 07:20:51:
Glad you mentioned that. It's been well-known since at least the 1950s that rooms for music performance or reproduction benefit from a ceiling height which isn't significantly different from the room's length and width, up to a point.
I don't remember if it's in Olson's "Music, Physics and Engineering" or Knudsen and Harris' "Acoustical Designing in Architecture", but I remember reading the statement that one dimension should not be significantly different from the others. One of the main reasons is to aid in obtaining good diffusion, i.e., to help create a desirable ambient sound field.
It IS rare when a person has the opportunity to hear music in the same room with two different ceiling heights, with the same loudspeakers - a real "before and after" perspective, so you're a lucky guy.
I'm curious as to what other acoustical changes were made to the room, such as surface finishes, furnishings, etc.
Also, keep in mind that there used to be a "boom box" above the 8 foot ceiling, and it's not there anymore, or at least it's greatly reduced. I'm suddenly reminded of a nightclub project I worked on in the late 70s. The owner wanted to improve the sound (which is always a good thing to hear!). The band stage was a raised, enclosed, space in one corner of the room. I said, "the first thing you need to do is to fill the cavity under the stage with a whole bunch of blankets, 'cause it resonates like a drum".
