摘要： The present invention relates to a device for damping sound in a pipe (7) which is adapted to having a gaseous medium flowing through it. The device (10) comprises at least one guide element (1 la-c) arranged inside the pipe (7) so that it divides an internal space in a portion (7') of the pipe into at least two flow channels (12a-d) for the gaseous medium. The guide element (1 la-c) comprises a plurality of holes running through it (11 ') which are so narrow that sound can pass through said holes (H') between mutually adjacent flow channels (12a-d) but only with a certain resistance.

摘要： An air turbine apparatus (10) for use with a combustion engine either as a muffler or as an air intake device is comprised of a housing (12) defining an expansion chamber (20) and an airfoil (50) positioned within the housing (12). The airfoil (50) includes a central aperture (52) extending longitudinally there through that is in fluid communication with both the inlet (18) and the outlet (16) of the housing (12). The airfoil (50) is configured to allow gases flowing through the inlet (18) to flow between the outer edge of the airfoil (50) and the housing (12) and through the aperture (52) of the airfoil (50). In addition, the air travelling through the housing (12) is caused to spin as it travels through the housing (12). This rotational flow increased the rate of flow of gases through the air turbine device (10). An induction tube (22) is provided between the airfoil (50) and the outlet (16) of the housing (12) to encourage turbulent flow of gases without restricting flow to produce a muffling effect and thus a dampening of noise from the combustion engine.

摘要： A sound silencer (10) for insertion in a duct having a fluid medium flowing therethrough includes an outer housing (20) having an open entry end (24), an open exit end (25), a base portion (21), a roof portion (22), and a pair of opposed sidewalls (23). The silencer further includes a plurality of spaced apart sound attenuating members (30) which are disposed upright within the housing (20). The sound attenuating members (30) are arranged in columns (X) and rows (Y), each of the sound attenuating members (30) being disposed substantially normal to the housing base (21) and extending from the base (21) to the housing roof (22) such that the sound attenuating members (30) define a first plurality of through passageways (L) substantial parallel to the direction of the main flow of the fluid medium and extending from the entry end (24) of the housing to the exit end (25) thereof and a second plurality of through passageways (W) disposed substantially perpendicular to the direction of the main flow of the fluid medium and extending from one of the housing side walls (23) to the other side wall (23). Each of the sound attenuating members (30) may be substantially filled with a sound absorptive material (34), with each face (31, 32) of the sound attenuating members (30) being acoustically transparent, or alternatively opaque. Thus, the silencer (10) combines dissipative, i.e., sound absorptive components (31, 32, 34) with the overall reactive configuration of the silencer (10) so as to effectively attenuate noise in a wide range of high and low frequencies.

摘要： A butterfly valve noise suppressor (10) is provided for reducing the noise generated by a gas flow passing through an open butterfly valve having a disc (16) pivotally mounted in a valve housing (12) for rotation about a transverse axis between an open and a closed position thereof. The noise suppressor (20) includes a plurality of flat and perforated baffle plates (22) arranged in a cruciform configuration, mounted in a flow path immediately downstream of the pivotal disc, axially extending and thereby dividing the downstream flow path into four axial and quadrant cross-sectional segments (24). The gas flow passing the edge of the pivotal disc in the valve generates a flow turbulence to form an unsteady large wake downstream of the valve. This unsteady wake is the source of noise. The cruciform baffle plates (21) permit the gas flow to pass therethrough without obstruction thereto, while allowing the turbulence to communicate laterally through the perforation (26), thereby dissipating the wake unsteadiness to reduce noise. The butterfly valve noise suppressor according to the present invention provides a better acoustic result compared to a muffler used in a conventional butterfly valve, and is lighter, durable, simpler and more economical to manufacture.
摘要翻译：提供了一种蝶阀噪声抑制器（10），用于减少通过打开蝶阀的气流产生的噪声，所述蝶阀具有枢转地安装在阀壳体（12）中的盘（16），用于围绕横向轴线在开口和其关闭位置。噪声抑制器（20）包括布置成十字形构造的多个平坦和穿孔的挡板（22），其安装在紧靠枢转盘的下游的流动路径中，轴向延伸，从而将下游流动路径分成四个轴向和象限横截面段（24）。通过阀中的枢转盘的边缘的气流产生流动湍流以在阀下游形成不稳定的大的尾流。这种不稳定的唤醒是噪音的来源。十字形挡板（21）允许气体流动而不阻塞气流，同时允许湍流通过穿孔（26）横向连通，从而消除尾流不稳定性以降低噪音。根据本发明的蝶阀噪声抑制器与常规蝶阀中使用的消声器相比提供更好的声学效果，并且更轻，耐用，更简单并且更经济地制造。

摘要： A system and method of attenuating noise generated in a multicylinder internal combustion engine as a result of opening and closing of the exhaust and intake valves in which cross passages extend between regions of the exhaust and intake manifolds adjacent the exhaust and intake valves of different cylinders in which the exhaust and intake valves open at approximately the same time. The acoustic waves of the noise caused by opening of the exhaust and intake valves respectively are set in mutual opposition to each other to thereby substantially cancel each other. A low mass flexible diaphragm in each cross passage prevents cross flow of exhaust gases while allowing transmission of the acoustic waves. Porous plugs restrict flow to the diaphragm while being sufficiently open to allow free transmission of the noise sound waves to the diaphragm to not impair the mutual cancellation process.
