摘要： In a soundproof structure body including a tubular tube body having an opening portion, and a resonance type soundproof structure, in which a phase difference θ, at an upstream of the resonance type soundproof structure, between a reflected wave in the resonance type soundproof structure and a reflected wave of a transmitted wave transmitted through the resonance type soundproof structure and reflected by the opening portion satisfies Inequation |θ−π|≤π/3 with respect to a resonance frequency of the resonance type soundproof structure. This soundproof structure body can effectively offset a reflected wave from a resonance type soundproof structure body by opening end reflection by appropriately specifying positions of the resonance type soundproof structure and the opening end portion of a duct, a tube line, or the like to improve an absorbance of a single resonance type soundproof structure.

摘要： Provided is a range hood that is small, that can reliably provide the flow path for waste smoke, that has high soundproof performance, and that allows oil stains and the like to be easily removed. The range hood includes: a suction portion that has a suction opening and that sucks air from below in a vertical direction; a connection opening connected to the suction portion; a duct portion that conveys air sucked from the connection opening and discharges the air from a discharge opening to an outside; an air blowing mechanism that is disposed in the duct portion and that moves air in the duct portion to the discharge opening; and a flow regulation plate that is disposed in the suction opening of the suction portion or is disposed so as to cover a part of the suction opening. A distance between the suction portion and the flow regulation plate is 110 mm or smaller. The range hood has at least one soundproof structure on a surface of the flow regulation plate on the suction portion side between the flow regulation plate and the suction portion.

摘要： A soundproof structure body includes a first tube structure and a second tube structure connected to the first tube structure and having a cross-sectional area different from the first tube structure, in which a structure body having a cross-sectional area smaller than a cross-sectional area of the first tube structure is installed in the first tube structure, and a transmission loss in a case where the structure body is installed in the first tube structure with respect to a case where the structure body is not installed in the first tube structure is positive at two frequencies adjacent to each other and difficult to generate an air column resonance mode in the first tube structure. This soundproof structure body generates a soundproof effect even at frequencies other than air column resonance of a tube structure such as a duct or a muffler, has a small size, and can obtain a high transmission loss in a wide-band.

摘要： A soundproof structure has two or more soundproof units. Each of the soundproof units has an outer shell having a cylindrical shape, has a hollow inner space inside the outer shell, and has a first opening portion opened to outside on a surface that is one end portion of the outer shell in an axis direction of the cylindrical shape. The two soundproof units adjacent to each other are disposed in the axis direction such that the first opening portions face each other. The first opening portions facing each other are spaced apart from each other in the axis direction. An average distance in the axis direction between the first opening portions facing each other is less than 20 mm. Accordingly, there are provided a soundproof structure and a soundproof system which can insulate sounds on the low frequency side with a simple configuration, are small and lightweight, and can easily change the frequency characteristics.
