Air-Coupled Acoustic Microsensor Technology
DARPA sponsored an Air-Coupled Acoustic Microsensors Workshop on August 24 and 25, 1999 in Crystal City, VA. This workshop facilitated an open exchange of ideas focusing on four broad acoustics topics: miniature microphone technologies, active noise control, sensor arrays, and nature-inspired acoustic sensor systems. The workshop provided a forum for discussion of the state-of-the-art, current challenges, and new ideas in these areas of research.
