Sound field control with hemi-cylindrical loudspeaker arrays

Hoffmann, Falk-Martin, Fazi, Filippo and Fontana, Simone (2016) Sound field control with hemi-cylindrical loudspeaker arrays At 2016 AES International Conference on Sound Field Control, United Kingdom. 18 - 20 Jul 2016. 15 pp.

Record type: Conference or Workshop Item (Paper)


An acoustical model for the sound field generated by hemi-cylindrical loudspeaker arrays is presented and a method for beamforming with said arrays is derived. The sound field model is obtained by introducing two independent boundary conditions for the sound field of a single impinging plane wave. The model for the radiation from a single loudspeaker in the array is then obtained from the reciprocity principle. Various beam patterns are presented and the theoretically predicted sound field is evaluated as a function of frequency. The results are discussed and an experimental array prototype is presented.
