Abstract: In a disk array apparatus, by taking note of a first sound of a specific frequency which is a noise element of original sounds generated from a fan, a second sound whose phase is inverted to that of the first sound is generated by a structure of a cooling air flow path passing through the fan, and the second sound is synthesized with the first sound on the cooling air flow path, thereby reducing the noise. For example, an exhaust duct is located on a fan unit in an upper part of the apparatus, two flow paths extending to an exhaust port are formed in an internal structure of the exhaust duct, and the two flow paths are designed so that the difference in the flow path length therebetween becomes equivalent to half wavelength of the specific frequency.

Abstract: A ventilation device comprises a body (11) having first and second ports (14, 15) and a ventilation passage (13) that extends through the body between the ports to allow airflow through the body. The ventilation device also comprises a noise attenuation device (21) arranged to attenuate noise transmission through the passage in at least one direction from the first to the second port. The noise attenuation device comprises at least one array (22, 23) of noise attenuation tubes disposed in the ventilation body. In one form, the noise attenuation device (21) include two arrays of attenuator tubes disposed on respective opposite sides of the passage (13). The tubes each have a mouth (27) that opens to the passage and a central axis that extends from the mouth in the direction of elongation of that tube. At least some of the tubes in the first array (20) oppose at least some of the tubes in the second array (23) with the central axes of the opposing tubes at the region of their mouths (27) being mutually inclined. In addition, at least one of the arrays include an acoustic transmissive partition (30) associated with at least some of the attenuator tubes. The partition (30) separates at least a portion of the cavities (28) of those tubes (27) from the ventilation passage (13). A framing system (40) is also disclosed to enable a bank of ventilation devices (41, 101) to be interconnected and coupled within a frame (60), particularly a glazing frame.

Abstract: A system and method are disclosed for enclosing electronic equipment in a noiseproofed and ventilated enclosure. This includes supplying air to an enclosure and removing air from the enclosure through acoustic chambers attached to the enclosure. The acoustic chambers can be constructed of materials or be treated with materials that have noise-absorbing or noise-abating properties. In addition, the acoustic chamber for exhausting air from the enclosure can contain baffles that help to prevent noise that has entered the acoustic chamber from leaving the chamber. And, the system and method can use a cable egress port that allows cables and wiring to pass through the egress port while blocking the transmission of noise through the egress port.

Abstract: The present invention relates to an air conduction element (1), particularly an air conduction channel for a motor vehicle, having a reverberant channel body (2) manufactured from plastic, which has at least one wall region replaced by a sound-absorbing component (10, 11), the sound-absorbing component having an at least partially exposed outer side. In order to be able to manufacture such an air conduction element cost-effectively with equal or even improved acoustic effectiveness, it is suggested that an edge region of the sound-absorbing component (10, 11) be extrusion-coated with the plastic of the channel body (2) in such a way that the sound-absorbing component (10, 11) is connected in a form-fitting way to the channel body (2) along at least a section of its circumference.

Abstract: An acoustic barrier systems that reduces the amount of noise entering the passenger compartment of a vehicle includes a secondary acoustic attenuator that extends from a primary acoustic barrier to a vehicle component case to envelop space around a conduit passing from the engine compartment to the component case. In one embodiment, the secondary acoustic attenuator extends from the primary acoustic barrier to the component case, with the secondary acoustic attenuator enveloping space around the conduit between the vehicle component case and the primary acoustic barrier. In another embodiment, the secondary acoustic attenuator is hingedly connected to the primary acoustic barrier to allow the secondary acoustic attenuator to be pivoted, from an orientation that allows installation of the vehicle component case, to another orientation wherein the secondary acoustic attenuator engages the vehicle component case to envelop space around the conduit between the vehicle component case and the primary acoustic barrier.

Abstract: Noise caused by the disturbance of the air flow is reduced. A flow straightening grid 30 is provided at an area where the air flow turns about 180 degrees in an air path 23, or in the vicinity thereof. Because of this, the air flow can be prevented from being disturbed in the air path 23 and, therefore, noise caused by the disturbance of the air flow can be reduced effectively.
