Abstract: A method for optimizing sound and vibration comfort in a mobile passenger compartment, the method applied by a design team to carry out overall design of the passenger compartment and/or by at least one equipment supplier to carry out design of a portion of the passenger compartment. The method establishes target values to be achieved for well-identified comfort indices, defines requirements and input data relating to plural equipment suppliers to obtain a totality of information relating to the passenger compartment, estimates values of the comfort indices and compares them with the target values, and then modifies individually or in combination the input data to correlate them with the target values.

Abstract: Window (9), fitted with fixed peripheral seal, has its edge (7) modified locally, e.g. by a buckling (11) of about 1 mm or by attaching a plastic or enamel projection of similar thickness to reduce noise radiation caused by acoustic field. Surrounding seal is similarly modified, and movement of the glass in the seal is diminished. Window glass has at least one edge distortion or increase in thickness, and the seal has at least one clip or hook in contact with the glass.

Abstract: The invention concerns a loudspeaker having an elongate parallelepiped hollow body, whereof one longitudinal surface is made up of a stretched elongate rectangular planar diaphragm. The diaphragm is suspended by its edges to the body adjacent side surfaces, and is integral with an elongate rigid inner part extending in the body longitudinal direction, and bearing a mobile electromagnetic coil, parallel to the diaphragm. The coil is arranged between two fixed magnets located along the body two longitudinal side surfaces which form, with the base of said body, polar parts. Said loudspeaker is useful as component of an active anti-noise system, associated with a double glazing.

Abstract: The invention relates to an acoustic insulating glazing unit.This glazing unit comprises two glass sheets (12, 14) joined together around their periphery by means of an assembly (16) forming a seal (163) and an insert frame (161) which defines, with the two glass sheets, a flat cavity filled with a gas, and a waveguide fastened between the glass sheets, internal to the insert frame. The waveguide consists of at least one straight tubular section (20, 22, 24, 26) placed on the periphery of the gas-filled cavity along one side of the glazing unit, this section being provided with a transverse partition (28) which closes the latter in its length direction, the said partition being placed at a length position along the section which depends on the acoustic mode of the cavity that it is desired to disorganize, this partition defining, on either side of it, two chambers (30, 31) which communicate with the cavity through the ends of the sections.
