摘要： A sound absorptive multilayer composite having an air-impermeable barrier, an air-permeable reinforcing core having an airflow resistance of at least about 100 mks Rayls and a thickness at least about 1/3 the final composite thickness, an air-permeable open cell foam or fibrous pad having an airflow resistance less than about 2000 mks Rayls and a thickness at least about 1/10 the final composite thickness and a semipermeable airflow-resistive membrane having an airflow resistance of about 500 to about 4000 mks Rayls can provide improved acoustic performance. For example, existing vehicular headliner designs may be improved by adding a properly chosen and properly positioned semipermeable airflow-resistive membrane, a properly chosen and properly positioned air-impermeable barrier, or a properly chosen and properly positioned open cell foam layer.

摘要： Sound insulation constructions, multilayer constructions for acoustically insulating a source of sound from a receiver that include one or more sound insulation constructions, structures comprising one or more sound insulation constructions and/or multilayer constructions, and a method for acoustically insulating a source of sound from a receiver. In some embodiments, the sound insulation construction includes a first layer and a second layer. The first layer can include a bonded fiber nonwoven web exhibiting a work of compression of at least about 0.7 kJ/m3 and an airflow resistance of no greater than 10,000 Rayls/m. The second layer can exhibit an airflow resistance of greater than 10,000 Rayls/m. In some embodiments, the method includes coupling the first layer to a surface of a vehicle to attenuate sound in at least a portion of the vehicle.

摘要： A driven rail vehicle comprises a carriage (1) with a drive unit arranged beneath the floor, connected for drive purposes with at least one of the bogies (2), supporting the carriage (1). According to the invention, a reliable cooling of the drive unit with an environmentally-friendly noise insulation is permitted, whereby at least one ventilator (24) is provided, which sucks cooling air into the encapsulation (5), by means of a noise-insulated inlet channel (18) and blows out of the machine chamber (6) through an exhaust opening (22), by means of a noise-insulated exhaust channel (23). Both the inlet opening (16) and the exhaust opening (22) are arranged transverse to the carriage longitudinal axis, in order to guarantee a cooling which is independent of direction of travel.

摘要： The invention relates to a method of producing sound-absorbing mouldings (1), more particularly for use as automotive front bulkhead linings or as automotive carpet backings. The method essentially encompasses the following steps: pneumatic application of different materials at least comprising virgin and/or recycled thermoplastic fusible fibres, recycled foam particles and recycled heavy-layer particles to a belt conveyor (5) or an area in such a way as to produce, from the materials, a mat-like two-dimensional structure (14), heating and pressing of the heated two-dimensional structure (14), in the course of which defined regions of the two-dimensional structure (14) are densified to differing degrees.

摘要： A formable laid interior decoration material (10) for an automobile is formed by laminating air-permeable design layer (11), apertured resin layer (12) having formed a plurality of apertures (12a) penetrating it in a thickness direction, shape-retaining felt layer (13) containing melted fibers, non-air-permeable resin sheet layer (14), and padding material (15), in this order. Formable laid interior decoration material (10) for an automobile is formed in a shape that conforms to a shape at a location where the material is laid in the automobile. The laminated body of air-permeable design layer (11), apertured resin layer (12), and shape-retaining felt layer (13) preferably has an air permeability of 1 to 30 cc/cm 2 /second.

摘要： The invention relates to an acoustically effective heat shield, especially for motor vehicles, which comprises at least two metal foils, especially aluminum foils, each provided with a plurality of knob-type embossed spots, at least one of the metal foils being perforated. The perforated metal foil has a plurality of holes having an average hole diameter in the range of from 0.05 to 0.9 mm. The holes are configured in the metal foil in a density of at least 15 holes per cm and the perforated metal foil is provided on one side with an adhesive layer that can be heat-activated above 120 DEG C and that is suitably perforated. The metal foils have a thickness in the range of from 50 to 200 mu m and form an unsupported structure. Said unsupported structure may especially consist of not more than three adhesive-coated metal foils. In an embodiment of the invention, the unsupported structure is configured from two metal foils and an interposed layer consisting of a sound-absorbing material.

摘要： The invention relates to a floor for an automobile. The invention is characterized in that the floor at least partially consists of a plastic support shell that comprises, on the interior facing the interior of the automobile, at least one area in which a cover layer, consisting of a wood veneer, is linked with the support shell across its surface. Preferably, the modulus of elasticity of the material of which the support shell consists in the area of the covering layer is higher than the modulus of elasticity of the covering layer.
