    摘要: It is possible to simultaneously identify the sound coming direction from a sound source in all directions and estimate the sound intensity of the sound source. A plurality of microphones (11) are arranged on the surface of a baffle (10) of a shape such as a sphere and polyhedron so that sound from all directions are acquired. A calculation device (40) calculates the amplitude characteristic and the phase characteristic of acoustic signals acquired by the microphones (11). The signal information and information on sound field analysis around the baffle are integrated and calculation to emphasize a sound coming from a particular direction is performed for all the directions so as to identify the sound coming direction from a sound source. According to these calculation results and the distance input by an input device (70), it is possible to estimate the sound intensity of the sound source at a plurality of portions generated at the sound source or boundary surface.

    摘要: An antenna apparatus for detecting an optimum directivity. The apparatus has an antenna capable of having plural directivities at predetermined directions; a scanning signal generator coupled to the antenna for generating a scanning signal for scanning the plural directivities from the first directivity to the last directivity; a signal level memory coupled to the antenna for memorizing plural memorized signals which are proportional to the output signal levels of the antenna at the plural directivities, respectively, when the plural directivities are scanned by the scanning signal; a detector coupled to the signal level memory memorized for detecting a maximum level memory signal from among the plural memorized signals after the scanning; and a controller coupled between the scanning signal generator and the detector for controlling the scanning signal generator in response to the maximum level memorized signal so as to fix the directivity of the antenna at the directivity corresponding to the maximum level memorized signal.

    摘要: The open air layer-type vibration reduction structure is provided with at least one plate-like member of which the obverse surface faces toward the open space side; and a frame spaced at an interval from the reverse surface of the plate-like member, and an air layer is formed between the plate-like member and the frame. An air-permeable ventilation portion is formed at least one of the plate-like member and the frame, such that the average value of the flow resistance on the surface of at least one of the plate-like member and the frame, which forms an air layer, is in a range greater than 0 N·s/m3 and equal to or less than 1,000 N·s/m3. The ventilation portion may be configured such that the sound pressure level generated within the air layer by applying an external force to the air layer is reduced by 3 dB or more.
