摘要： PURPOSE:To prevent an acoustic impediment, by a method wherein some of the specified surfaces on three- or four-face cyclorama are composed of slant cycloramas allowed to slant toward a ceiling or composed of acoustic absorption cycloramas. CONSTITUTION:In the case of three-face cycloramas, two faces opoposed to each other are composed of slant cycloramas 3 and acoustically reflected waves are allowed to arrive at a ceiling thereby. The ceiling is composed of an acoustic absorption wall 4 and reflected sound of higher order is absorbed thereby. All of them are composed of the slant cycloramas 3 or either of the two faces opposed to each other is composed of the slant cyclorama 3, if necessary. In the case of four-face cycloramas, at least two face neighboring to each other are composed of the slant cycloramas. As substitute for these cases, in the other case of the three-face cycloramas, two face or at least one face of two faces opposed to each other is composed of an acoustic absorption cycloramas and in the other case of the four-face cycloramas, at least two faces neighboring to each other are composed of the acoustic absorption cycloramas. Combinations of the slant cycloramas with the acoustic absorption cycloramas also meet this requirement. In this way, a flutter echo and the excess of reverberations can be avoided, and an acoustic field at the side of fields can be suitably kept.

摘要： PROBLEM TO BE SOLVED: To provide a method for evaluating sound insulation performance between adjacent chambers and a selected side wall capable of calculating and evaluating quantitatively the sound insulation performance of the side wall by calculating a side wall solid propagation sound between the adjacent chambers as a vibration acceleration level propagating inside the side wall. SOLUTION: When evaluating the sound insulation performance between adjacent chambers enclosed by the side wall 4 intersected with a door boundary wall 3, the sound pressure level of a propagated side wall solid propagation sound (a symbol of a trancated chevron shape) is calculated as a sound pressure level determined from the sound pressure of a sound source chamber 1 after entering the side wall 4 on the sound source chamber side, being propagated inside the side wall 4 with internal damping, and being radiated from the side wall 4 on the sound receiving chamber 2 side, and synthesized quantitatively with a direct transmission sound through the door boundary wall, to thereby calculate the sound pressure level in the sound receiving chamber. Hereby, the sound insulation performance between the adjacent chambers is calculated and evaluated quantitatively.

摘要： PURPOSE:To simulate and experience a sound field in a design stage by performing conversion corresponding to acoustic characteristics in plural directions of the periphery of a sound reception point and generating a simulated acoustic signal, and applying simulation acoustic signals to speakers provided corresponding to the plural directions. CONSTITUTION:A simulation converting means 17 converts the acoustic signal 32 from an acoustic signal source 16 according to the acoustic characteristics in the respective directions D1 - D3 to generate the simulation acoustic signals 34 corresponding to the directions D1 - D3. Further, the speakers 22 are provided in the sound field 10 corresponding to the directions D1 - D3 of the sound field 1. Then when the simulation acoustic signals 34 are applied to the speakers 22, the speakers 22 in the simulated sound field 10 receive sounds similar to the sounds in the directions D1 - D3 in the sound field 1 although an evaluating person 7 in the simulated sound field 10 is not in a sound field to be evaluated actually. Consequently, the sound environment at the sound reception point 5 in the sound field 1 can be simulated and experienced.

摘要： PROBLEM TO BE SOLVED: To form sound-insulating walls as separation walls of acoustical various rooms in structure, in which the sound-insulating walls can correspond to the time of the generation of the change of a site planning, and to ensure a sound field clearer than that in the case where plasterboards are used on surfaces on the insides of the rooms. SOLUTION: The sound-insulating wall is composed of a fixed sound- insulating wall 2 consisting of a precast concrete board arranged between an upper-layer side slab 4 and a lower-layer side slab 5 and a floating sound- insulating wall 3 made up of the precast concrete board forming a space between the floating sound-insulating wall 3 and the fixed sound-insulating wall 2 and being disposed onto the lower-layer side slab 4. A floor board 6 consisting of concrete is laid on the lower-layer side slab 5 under the state, in which the floor board 6 is not brought into contact directly with the lower-layer side slab 5, and the floating sound-insulating wall 3 is arranged onto the floor board 6.

摘要： PURPOSE: To reduce air swishing sound and lower the rate of water leakage without increasing pressure loss. CONSTITUTION: In an external facing vertical louver 1, both end faces (surface) on the building inner-outer parts 6, 5 side of each blade plate 4, and the building inner-outer part side surface 11a of a groove part 11 in the top part 7 of each blade plate 4 are formed into curved faces so as to prevent the swirl of air flow and thereby to lower pressure loss, and also the rate of water leakage is lowered by a groove part 11 provided at the top part 7 of each blade plate 4. In addition, the pitch (a) of each blade plate 4 can be reduced by lowering pressure loss and the rate of water leakage. In the external facing vertical louver 1, neither pressure loss nor air swishing sound is thus increased even in the case of providing the groove part 11 at the top part 7 in each blade plate 4 in order to lower the rate of water leakage and reducing the pitch (a) of each blade plate 4.
