This paper describes a two-dimensional sound source localization method which uses the directional pattern of each microphone to perform acute beam forming in azimuth and elevation using a 32-channel distributed microphone array. The localization method is based on delay and sum beam forming (DSBF) and frequency band selection (FBS). The microphone arrangement is determined by simulation of the proposed...
This paper proposes a method for synchronizing plural personal computers for developing a large-scale loudspeaker array system. Loudspeaker array system has to be controlled by a personal computer. The loudspeaker array system can generate high sound pressure areas. The loudspeaker array system is controlled with micro sec order. The loudspeaker array system is required to be enlarged for serving...
