Abstract: The present disclosure relates to a method for masking a language signal in a zone-based audio system, involving: acquiring, in an audio zone, a language signal to be masked; transforming the acquired language signal into spectral bands; interchanging spectral values of at least two spectral bands; generating a noise signal on the basis of the interchanged spectral values; and outputting the noise signal as a masking signal for the language signal in another audio zone.

Abstract: An operator control unit for a steering wheel and a steering wheel having such an operator control unit. The operating control unit having a housing which is insertable into a steering wheel spoke of the steering wheel and which has at least one housing side wall and a housing base, having an electrical contact element provided in the housing, and having at least one actuating element which is mounted movably on the housing and which acts with an electrical switching action on the contact element. In order to extend the functionality of the operator control unit but maintain the compact structural form, it is proposed that the operator control unit have a fan for a steering wheel temperature control arrangement and a flow channel which is acted on by the fan, which flow channel is formed by the housing base and has an inlet and outlet opening on the housing.

Abstract: A headrest (1, 101, 102) is disclosed, with a support structure (2) and with at least one speaker basket (7.1, 7.2) for a speaker (6.1, 6.2) provided on the support structure (2). In order to achieve a simply designed and durable headrest (1, 101, 102), the proposed support structure (2) transitions integrally into the speaker basket (7.1, 7.2) and forms the latter.

Abstract: A motor vehicle steering wheel with at least one gripping portion for gripping the steering wheel by a driver and with a central steering wheel region which is connected with the gripping portion is provided. The central steering wheel region—based on the state of the steering wheel properly mounted in a motor vehicle—forms a cover surface facing the driver, wherein behind the cover surface a receptacle for a gas bag is arranged and the cover surface defines an outlet opening through which the gas bag can be deployed for the protection of the driver. The steering wheel furthermore comprises an electronic display device with a screen. The screen is provided beside the outlet opening on the cover surface of the central steering wheel region, and the surface of the screen amounts to at least 60% of the opening cross-section of the outlet opening.
