Back a while ago I posted on how much better the community band sounded when set up right in front of a wall in the town park as opposed to being out in the middle of it. We could hear ourselves better and the audience could as well.
Last week the Kenwood Players performed what Erik Satie might have called "furniture music" for a Health Fair put on by U.Va. hospital and a number of local non-profits.
Free mammograms and sports physicals for school children, along with lots of information booths and free screenings, were on offer for non and under-insured folks.
The locale was the gym in the new field house at the high school in town. The way we set up, Dick on trumpet had his back directly to a wall and Bill B on soprano sax had his back to the corner of the huge room furthest from us. In the recording, Dick is perfectly clear and Bill B sounds as if he's in the next county, and they were equidistant from the mics.
At the time we were playing this disparity wasn't obvious because of the booming acoustics of the gym and because I was usually standing closer to Bill B than to Dick. There was also a thick pad on the wall right behind Dick and I assumed it would soak up a lot of his sound, but anything reflects better than nothing. Also, the recorder was out in front of us a bit, and other than setting a level, I didn't really pay attention to the sound and the balance.
The basic lesson in all of this is not to make assumptions, but to walk around and pay attention to how the acoustics are working.
