摘要： PROBLEM TO BE SOLVED: To prevent the film vibration of a film-shaped sound-absorbing material from being disturbed by a resonance hole for Helmholtz resonance formed in the film-shaped sound-absorbing material in a sound absorbing body for collectively exhibiting sound absorbing action by film vibration and sound absorbing action by the Helmholtz resonance.
SOLUTION: An aperture section 18a of a cavity 18 is closed with a film-shaped sound-absorbing material 20. The film-shaped sound-absorbing materials 18a are stacked by sticking a stripe 28 to a corner section of the film-shaped sound-absorbing material 18a. The resonance hole 30 is formed by penetrating through this stacked section. The resonance hole 30 is connected through the cavity 18. A forming position of the resonance hole 30 is within 20% of dimensions L1 and L2 of a face of the film-shaped sound-absorbing material 20, from fixed ends 32 and 34 of a peripheral section of the film-shaped sound-absorbing material 20. A Helmholtz resonance frequency is adjusted by a film thickness of the stripe 28 or a cross section of the resonance hole 30.

摘要： PROBLEM TO BE SOLVED: To provide a floor structure which is lightweight and reduces a level of floor impact sound, and to provide a floor underlayer panel used for the floor structure.
SOLUTION: In the floor underlayer panel 40, an area on a supporting board 33 of a vibration-proofing support leg 30 is formed to be solid. In the other area, a plurality of cavities 41 are formed to extend in parallel to a floor surface. The vibration energy transmitted from an impact point of the floor underlayer panel 40 is reflected at a border between the cavitied area, and the solid area, and the energy passes the cavitied areas repeatedly. Consequently, the energy attenuates in a short time and the vibration energy or sound energy transmitted to a slab 20 is reduced.

摘要： PURPOSE:To obtain an excellent articulation with a comparatively small loudspeaking sound level even when a noise level is high. CONSTITUTION:An equalizer 38 inputs an announcement sound 40 outputted from a microphone 32 or a reproduction device 34 to perform equalizing on a DOWN side on a broad band with its spectrum peck frequency (nearly 250Hz) as a center. A sound volume adjustment means 42 adjustment signal 40 with sound volume adjusted is amplified by a announcement signal 40 with sound volume adjusted is amplified by a power amplifier 44 and the sound radiates from speakers 48 arranged in a space 46 to be loudspoken. A sound volume adjustment control means 60 decreases the sound volume when a noise level is small and increases the sound volume when the noise level is large, decreases relatively the sound volume when a noise frequency characteristic is of a lower or medium frequency band type and increases relatively the sound volume when the noise frequency characteristic is of a higher frequency band type.

CONSTITUTION:A low-pitched sound absorbing panel 11 has a surface plate 12 forming the panel surface, and the surface panel 12 forms an air layer with a wall surface WA. On one side edge of the low-pitched sound absorbing panel 11, a slit member 13 having a slit 13a formed thereon is arranged. In the back of the slit member 12, a sound absorbing material 14 for increasing the acoustic resistance of the slit 13a of the slit member 13 and consuming acoustic energy is arranged. In the middle part of the low-pitched sound absorbing panel 11, a partitioning member 15 for determining the depth L of the air layer in the rear of the slit member 13 is provided with a determined space from the slit member 13. The other edge of the low sound absorbing panel 11 is blocked by a column 17. The low-pitched sound absorbing panel 11 has a slit type resonator formed in parallel to the wall surface.

摘要： PURPOSE:To improve the sound absorption effect and sound insulation effect in a low-pitched sound by arranging at least two light insulating plate bodies not in parallel. CONSTITUTION:At least two sound insulation plate bodies 13 and 14 are arranged not in parallel. In this case, the two sound insulation plate bodies 13 and 14 are arranged no in parallel and the distance between them is not constant, so the frequency of a specific sound wave which causes the sound insulation plate bodies 13 and 14 to resonate and vibrate is dispersed and the quantity of a decrease in the degree of sound insulation is reduced. Further, a sound absorptive internal layer panel 11 is fitted directly to the sound insulation panel 11 to form a triangularly sectioned air layer space between the light insulation panel 12 and sound absorptive internal layer panel 11. Consequently, the sound insulation effect and sound absorption effect in the low-pitched sound range are improved.

摘要： PURPOSE: To effectively prevent an echo to suppress the reduction of the reverberation by forming an sound absorption surface, which absorbs sounds coming from a specific direction well, and a reflection surface which reflects sounds in plural directions different from the coming direction and is divided into small surfaces. CONSTITUTION: An acoustic panel 10 is formed into a rugged shape by small divided surfaces 10a to 10d directed to a plurality of directions, and projecting parts 11 and recesses 12 on the surface are so formed that their sections are trapezoidal, and they are arranged alternately and regularly. Tops 10a of projecting parts 11 and bottoms 10c of recesses 12 are flat and are formed in parallel, and tops 10a are made wider than bottoms 10c. Tops 10a are formed into sound absorption surfaces P by glass wool 13 and perforated plates 14 over it, and inside surfaces 10b, 10c, and 10d of recesses 12 constitute reflection surfaces Q by imperforate plates. Thus, not only sounds in a specific direction are absorbed well but also sounds are reflected in a plurality of different directions to effectively prevent an echo, and reduction of the reverberation time is suppressed.
