A method for the joint localization and orientation estimation a directional sound source using distributed micro-phones is presented. By modeling the signal attenuation due to the microphone directivity, the source directivity, and the source-microphone distance, a multi-dimensional search over all possible sound source locations and orientations is performed. This sound source scene reconstruction algorithm is presented in the context of an experiment with 24 microphones and a dynamic speech source. At a signal-to- noise ratio of 20dB and with a reverberation time of approximately 0.1s, accurate location estimates (20cm error) and orientation estimates (less than 10{sup}o average error) are obtained.
