Abstract
Abstract Translated from German 2.1. Bei bekannten Funkempfängern wird bei Unterschreitung einer bestimmten Empfangsfeldstärke ein Signalton über einen Lautsprecher abgestrahlt. 2.1. In known radio receivers, a signal tone is emitted via a loudspeaker when a certain reception field strength is undershot. 2.2. Um einen Benutzer durch dieses akustische Signal so wenig wie möglich zu beeinträchtigen wird vorgeschlagen, als akustisches Signal ein Rauschsignal zu verwenden. 2.2. In order to impair a user as little as possible with this acoustic signal, it is proposed to use a noise signal as the acoustic signal.
