n interactive tool for use in the field," says Girod. "A scientist should be able to note something that just happened a second ago, and immediately 'drill down' on that event with an interactive signal-processing tool box."

Each VoxNet node is a portable, self-contained processor with a small four-channel acoustic array. Using a distributed set of nodes, a forested habitat can be monitored and the behavior of animals can be recorded and analyzed acoustically. The team deployed their VoxNet system in a recent bioacoustic census, collecting data during a trip to Chiapas, Mexico at the Chajul Biological Field Station, located in a region of dense rain forest. It is home to Mexico's most diverse ecosystem. VoxNet performed well in this harsh environment, despite a few audio glitches resulting from the high humidity. So far, the team has recorded a set of raw data as part of an ongoing project to obtain local census estimates based on observation of bird calls.

Paper 2aAB15, "Experience with VoxNet: a rapidly-deployable acoustic monitoring system for bio-acoustic studies." will be presented at 1:00 p.m. on Tuesday, July 1 in room 342B.

6) BATS CAN DIRECT THEIR "GAZE"

The echolocating bat controls the direction and distance of its acoustic "gaze," according to Cynthia Moss (cmoss@psyc.umd.edu) of the University of Maryland. It produces ultrasonic vocalizations and uses information contained in the returning echoes to build a 3D auditory "image" of its surroundings. The timing, bandwidth, and duration of echolocation signals directly impact the information available to the bat's acoustic imaging system. In turn, the bat's auditory representation of space guides its actions: ear movements, head aim, flight path, and the features of subsequent ultrasonic vocalizations. Moss's latest research indicates that bats encountering a complex environment were found to shift the direction and distance o
