Abstrakt

We present a method to estimate the orientation of a directional
sound source and experimental results illustrating
its performances. The method requires recordings captured
by an array of microphones at known positions with
respect to the source as well as the source directivity. Experiments
have been performed in an ordinary environment
by using a Polaroid transducer as the sound source emitting
a broadband signal in the ultrasonic range. Such an
acoustic signal has similar structure to those used by bats
to echolocate. Results show that method is precise provided
that the source directivity ensonifies the microphone array
sufficiently. Further developments of the method, and its ultimate
application to the reconstruction of emitted bat calls
from remote recordings, are discussed.
