d demonstrate the Conference Center's pipe organ, which contains 7,708 pipes in its 130 ranks. In Longhurst's presentation, attendees will hear the acoustical behavior of a pipe organ in a very large room (3aAA5). Jack M. Bethards of Schoenstein & Co. Organ Builders of San Francisco (jack@schoenstein.com) will discuss the acoustical and architectural considerations for installing organs in large spaces (3aAA4).

SCIENCE OF JAZZ AND YODELING

An evening tutorial and lecture on the first day of the meeting (June 4) will feature the Salt Lake City Jazz Orchestra. Uwe Hansen of Indiana State University (u-hansen@indstate.edu) will describe the basic science of each instrument family: strings, brasses, woodwinds, piano and percussion. Orchestra director Jerry Floor and his players will then perform illustrative demonstrations of each family. The program will conclude with ensemble performances of famous pieces (1eID1). On Tuesday morning, June 5, sixth-grade students will experience hands-on demonstrations of acoustics, including musical instruments and a "ping-pong cannon" that creates shock waves as it shoots balls at high speeds. On Tuesday afternoon, Bill Strong of Brigham Young University (william_strong@byu.edu) will present a mini-concert on yodeling, by expert yodeler Kerry Christensen, who will demonstrate alpine, classical, and humorous yodeling styles (Session 2pMUb).

PREVENTING TERRORIST ACTIVITY IN PORTS AND HARBORS

Acoustics can make ports and harbors more secure. Karim Sabra of the Scripps Institution of Oceanography (ksabra@mpl.ucsd.edu) will present encouraging proof-of-concept measurements of an "acoustic tripwire" surveillance system for detecting intruders in harbor entrances. Their technique is designed for the shallow-wat
