| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes control of distance attenuation using spherical loudspeaker array. One research group proposed radial filtering with spherical microphone to control the sensitivity to distance from a sound source by modeling the propagation of waves in spherical harmonic domain. Since transfer functions do not change when the input and output are swapped, we can apply the radial filtering for microphone arrays to the filter design of distance attenuation control with loudspeaker arrays. Experimental results confirmed that the proposed method is effective in the low frequencies. |
