Abstract: The public address system 1 comprises a transmission medium 4 having a loop shape and a plurality of loudspeakers 3. The transmission medium 4 transmits a transmission signal therethrough in a first direction and in a second direction opposite to the first direction. The transmission signal includes a communication signal having a predetermined frequency range and an audio signal having a different frequency range than the communication signal. The public address system 1 further comprises a first filter unit 51 connected to the transmission medium 4 that is configured to filter the transmission signal to attenuate the communication signal and output the audio signal. The first filter unit 51 is connected to the transmission medium 4 such that the communication signal is prevented from transmission in the first direction while the communication signal and the audio signal are transmitted in the second direction.

Abstract: Problem to be SolvedTo effectively operate a microphone array provided with a sound source position estimating function.SolutionA microphone control system of the present invention is realized by the use of a tablet-type computer, for example. On the display of the control system, a two-dimensional simulation diagram 302, for example, simulating the space in which the microphone array is disposed. An array mark 304 simulating the exterior shape of the microphone array is displayed on the simulation diagram 302. Further, a sound source mark 316 indicating the position of the sound source estimated by the microphone array is displayed on the simulation diagram 302. Thus, an operator can intuitively find the position of the sound source in the space in which the microphone array is disposed, by referring to the simulation diagram 302, the array mark 304 and the sound source mark 316 displayed on the simulation diagram. Thus, the usage of the microphone array is improved.
