摘要： PROBLEM TO BE SOLVED: To provide a small-sized speaker for acoustic reduced scale model experiment suitable for an acoustic reduced scale model experiment.
SOLUTION: A PZT driver 24 is fitted to the inside of each face of a speaker cabinet 12 of a dodecahedron shape by using a bass bar 18, a bolt 20, spacers 22, 26, and a nut 28. Damper weights 32 are adhered to both ends of the PZT driver 24. Applying an electric signal to the PZT driver 24 vibrates the PZT driver 24 to deliver the vibration to a diaphragm 14 thereby emitting sound externally. In the case of the PZT driver 24 without the damper weight 32, split vibration may take place in the diaphragm 14 at a some frequency, since the damper weights 32 are fitted to the PZT driver 24, the occurrence of the split vibration in the PZT driver 24 can be suppressed to provide a flat frequency characteristic.

摘要： PROBLEM TO BE SOLVED: To provide a double ceiling which efficiently prevents heavy weight floor impulsive sound. SOLUTION: An attic space is provided between a ceiling slab and a ceiling plate below the slab in a double ceiling. Sound velocity in the attic space is lower than that in air by covering a whole upper surface of the ceiling plate 4 with a porous material 12 having a large acoustic internal loss and substantially filling the whole attic space 10 with the porous material 12. Accordingly, a refractive index of the porous material 12 is set in a way that a resonance frequency in the attic space 10 is lower than a sound range subjected to regulation.

摘要： PROBLEM TO BE SOLVED: To measure a sound absorption coefficient over a wide frequency band by one measurement without deteriorating an accuracy.SOLUTION: The sound absorption coefficient measuring device 10 excites a sound field in a tube from a sound source of a speaker 50 by supply of a sound signal from a sound source supply section 34. A sound pressure acquiring section 32 acquires sound pressures at two points of a measurement point A and a measurement B when exciting the sound field. A correlation relationship operating section 26 obtains a correlation function C(τ) related to the time between the two points of the measurement point A and the measurement B using the history of the acquired sound pressures. A wave packet extracting section 28 extracts a first wave packet and a second wave packet, in an order counted from the smaller delay time (time lag) τ, from the correlation function C(τ). A sound absorption operating section 30 obtains a sound pressure reflectance using the first wave packet and the second wave packet, and then obtains a sound absorption coefficient α using the sound pressure reflectance.

摘要： PROBLEM TO BE SOLVED: To provide a sound isolating structure capable of stably and efficiently shutting heavy floor impact sound at a story floor having many low frequency components by an active control. SOLUTION: Noise caused in an upper living room is transmitted to a cavity 14 through a floor 10. The noise transmitted to the cavity 14 includes the low frequency components of 250 Hz or less corresponding to the natural resonance frequency of the floor 10. The noise caused in the upper living room is detected by a reference microphone 18, and noise signals are outputted to a controller 24. On the other hand, residual sound remaining in the cavity 14 without being muffled is detected by an error microphone 22, and error signals are outputted to the controller 24. The controller 24 performs an adoptive control so that the error signals become minimum by using the inputted noise signals and error signals. Control signals obtained are outputted to a speaker 20. The speaker 20 radiates control sound generated according to the control signals toward the inside of the cavity 14. In the cavity 14, the noise is canceled by the radiated control sound. As a result, the vibration of a ceiling board 16 is prevented from occurring and the propagation of the noise to a lower living room can be prevented from occurring. COPYRIGHT: (C)2005,JPO&NCIPI
