"I've read Dr. Griffin's paper, and while it is generally good, it does overlook much of the near-field issues that a good strong reference (Steven's recommendation of Fundamentals of Acoustics by Kinsler et al is excellent) cover."

Then he said here days later;
"Anyway, IF you had to do a near-field line array, I think Dr. Griffin's paper is a good starting point, and said so up-front."
