摘要： PROBLEM TO BE SOLVED: To provide a block embedded in a road surface, which almost enables a pinpoint audio assist by reducing an audible range to a narrow one. SOLUTION: This block 100A for being embedded in the road surface is constituted by arranging a planar loudspeaker 2 in an internal space (a space formed of recesses 1a and 4a), formed below an upper wall portion 4b, in parallel with a top surface of the upper wall portion 4b. Since the directivity of the planar loudspeaker 2 is lower than that of a cone loudspeaker, the audible range of the audio assist becomes narrower than that the audio assist of a conventional block embedded in the road surface, so that the pinpoint audio assist can be realized.

摘要： PROBLEM TO BE SOLVED: To provide a simple and inexpensive broadcast system which supports evacuation guidance using sound. SOLUTION: N numbers (N: plural number) of speakers 12 are spaced along a guiding direction 100. The speakers 12 are connected to a wideband sound source system 18 through band pass filters 14 corresponding to them and a common pre-amplifier circuit 16. The wideband sound source system 18 outputs white noise signal as guiding signal. The band pass filters 14 have frequency characteristics different from each other, and specifically, the frequency characteristics is so set that a speaker 12 closer to an evacuation gate emits a guiding sound higher in frequency. Evacuees can reach the evacuation gate by advancing in such direction as the guiding sound becomes higher in frequency. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To always realize a normal adaptive operation. SOLUTION: In order to negate noise transmitting through an exhaust duct 1 with an acoustic wave emitted from a secondary sound source loudspeaker, a Filtered-x LMS algorithm executing part 8 controls the transfer function W of a filter 3 so that the composite transfer function of the transfer function W of an FIR adaptive digital filter 3 and a transfer function C occurring between the filter 3 and an error microphone 6 becomes equal to the transfer function P of the exhaust duct 1. In order to constitute its control system from a Filtered-x LMS algorithm, the amplitude or the phase of the transfer function CI of an FIR digital filter 7 with an identified transfer function C is changed until it becomes equal to the transfer function C when the transfer function C is changed.

摘要： PROBLEM TO BE SOLVED: To prevent divergence of a control system having a filtered-x LMS algorithm constitution. SOLUTION: Let Wk be the transfer function of an adaptive filter 3. Let C=Ca (1+P2 ) be a secondary sound path, which exists between the output side of the filter 3 and an error microphone 6 through a loudspeaker 5 and a portion of an exhaust duct 1, and P=P1 (1+P2 ) be a primary sound path between a reference microphone 2 in the duct 1 and the microphone 6. Then, the transfer function Wk of the filter 3 is controlled, so that a combined transfer function [C×Wk] becomes complementary to the sound path P. Thus, exhaust sound propagated in the duct 1 is canceled by control sound generated by the loudspeaker 5. When a transfer function Cah, that is equivalent to the case in which only a direct sound path Ca is identified, is set in an FIR filter 7 for compensating for the path C, divergence of the control system is prevented by the effect of a reflected sound path P2 .

摘要： PROBLEM TO BE SOLVED: To avoid the effect of a dip caused by a traveling wave and a reflection wave. SOLUTION: An expansion muffler 8 is provided in the vicinity behind a position of an error microphone 6 of an exhaust duct 2 so as to form an abrupt impedance change part 8a at which an acoustic impedance in the exhaust duct 2 is suddenly changed. Thus, an exhaust sound propagated in exhaust duct 2 is reflected in the abrupt impedance change part 8a. Then the reflected wave and the exhaust sound (traveling wave) are interfered with each other resulting being cancelled and a part with a small sound pressure, that is, a dip is produced in the exhaust duct 2. Then a distance L' between the abrupt impedance change part 8a and the error microphone 6 is reduced. Thus, the frequency at which the dip caused is shifted toward a high frequency from the silencing object frequency band at the position of the error microphone 6, resulting is avoiding the effect of the dip onto the silencing operation.

摘要： PURPOSE:To provide an automatic loudspeaker sound controller which can automatically improve the clarity of the loudspeaker audio signals in a sound field. CONSTITUTION:The audio signals produced from an audio signal source 2 are transmitted to a sound field 10 through a speaker 12. The noise levels are detected in the field 10 by a microphone 20, a delay circuit 24 and an FIR filter 26. Then the audio signals undergo the analysis of frequency through a frequency analyzing means 14. The noise level detection signal and the frequency analysis result are supplied to a fuzzy inference part 30 where the fuzzy inference is carried out. Thus the attenuated variable of a variable attenuator 6 and the equalized variable of an equalizer 4 are controlled based on the result of the fuzzy inference.
