Spherical microphone array beampattern design for improved room acoustics analysis Conference Paper uri icon

abstract

  • Spherical microphone arrays have been recently studied for sound-field analysis in auditoria. Beamforning was employed for spatial separation of individual reflections from the stage to the seating area, therefore providing detailed spatial mapping of sound propagation. In this work beampattern design for spherical microphone arrays is employed to achieve improved analysis of the sound field. Spatial �spectral� temporal trade-offs in the sound-field analysis will be discussed. Finally, experimental results from auditorium measurements will be presented.
