摘要： PROBLEM TO BE SOLVED: To provide an acoustic device of a vehicle which can obtain sufficient acoustic pressure of suction noise propagated in a cabin, with respect to a constitution in which the suction noise of an internal combustion engine is propagated into the cabin. SOLUTION: The acoustic device 1 connecting a surge tank and a dash panel includes a duct member 5, a film unit 6 on the dash panel side, and a film unit 7 on a cowl side. In the duct member 5, openings 5B and 53a opening to the dash panel side and the cowl side, respectively, are formed. The film unit 6 on the dash panel side and the film unit 7 on the cowl side are mounted on the opening 5B of the dash panel side and the opening 53a of the cowl side, respectively. In the respective film units 6 and 7, punching panels made of metal are superposed on inner surfaces of the duct member 5 relative to films 61 and 71, which are made of resin thin films. Thus, the films 61 and 71 can be made thinner, allowing propagation efficiency of the suction noise to be enhanced. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a sound diffuser capable of obtaining diffusion effects in a comparatively broad band including a low sound region with a comparatively thinner configuration.
SOLUTION: In the sound diffuser 10, a plurality of space areas 16 are formed by forming and projecting a partition wall 14 of a parallel cross shape, in front of a plate member 12. A rear section of each space area 16 is closed with the plate member 12, and an aperture section 16a is formed in a front section. Each aperture section 16a is respectively closed with a film shape sound absorbing material 18. Height of arrangement of faces of the film shape sound absorbing materials 18 differs between adjoining space areas 16 and 16, and thus, layer thickness of a rear air layer of the film shape sound absorbing material 18 varies.

摘要： PROBLEM TO BE SOLVED: To provide a construction method for an acoustic room, which can simply bring about desired acoustic characteristics. SOLUTION: After the diffusion panel 10 is arranged in such a manner as to cover the whole of a sound insulation layer 51 for covering a wall surface 50 of the acoustic room 40, a sound absorbing panel 20 is temporarily fixed to a surface of the diffusion panel 10. An audition is performed in this state, and an installation condition of the panel 20 is changed when the desired acoustic characteristics are not obtained. When the desired acoustic characteristics are obtained, the panel 20 is permanently fixed to a position to be installed, and a transmission panel 30 is arranged in a position to nonoverlap the panel 20. Thus, the desired acoustic characteristics can be obtained without changing an installation condition of the diffusion panel 10. Furthermore, a sense of discomfort in terms of a design can also be eliminated by the transmission panel 30. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a hollow panel which can effectively exert sound insulation performance while suppressing the thickness of the panel and accomplishes labor savings in panel forming work and a reduction in manufacturing cost by reducing the number of components.
SOLUTION: This hollow panel 10 is formed in such a manner that a hollow part 12 is provided between almost planar outside parts 11 on obverse and reverse sides. In the hollow panel 10, a mass per unit area is made partially different, so that a sound insulation defect can be prevented from being caused by coincidence effects at a specific frequency. The hollow part 12 is set to have a plurality of kinds of widths, so that sectional areas can be made different from one another; and the mass per unit area or rigidity is made nonuniform, for example, by a difference in mutual separation distance between bulkhead parts 13 or the thicknesses of the bulkheads 13, so that the sound insulation defect can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an onboard audio system capable of performing control so that an audio signal is easy to listen to even in any driving state. SOLUTION: Noises in an interior of an automobile are estimated based on sensed values of sensors that sense a vehicle speed (travelling speed), an accelerator opening angle, and an engine speed respectively. This estimation is carried out by searching a noise estimation database. A masking characteristic of an audio signal is deduced based on the estimated noises. An equalizing characteristic to prevent a masking of the audio signal is decided based on the masking characteristic, and then the audio signal is equalized. COPYRIGHT: (C)2006,JPO&NCIPI
