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.
