    • The invention relates to a headset comprising a first housing (LK, AK, IK) for receiving an electroacoustic converter and a second housing (RK, AK, IK) for receiving an electroacoustic sound transducer, at least one outer microphone (M1) for recording outside noise, and at least one inner microphone (M2) for recording sound in the region between an ear of the user and the first and/or second housings (LK, RK, AK, IK). The headset further comprises a digital active noise reduction unit (ANR) for performing active noise reduction based on the sound recorded by the at least one outer microphone and the at least one inner microphone. The active noise reduction unit (ANR) comprises an analysis unit (AU) for analyzing the sound recorded by the outer microphone and the inner microphone and for determining the signal types of the recorded sound. The active noise reduction unit further comprises a plurality of signal processing units (SVE1 - SVEn), which are each designed to perform active noise reduction for a signal type. The analysis unit (AU) selects at least one of the signal processing units (SVE1 - SVEn) for performing a noise reduction step based on the analysis that was performed of the recorded sound.
    • 本发明涉及一种耳机,包括用于接收电声转换器的第一外壳(LK,AK,IK)和用于接收电声音换能器的第二外壳(RK,AK,IK),至少一个外麦克风(M1) 外部噪声,以及用于在用户的耳朵与第一和/或第二外壳(LK,RK,AK,IK)之间的区域中记录声音的至少一个内部麦克风(M2)。 耳机还包括用于基于由至少一个外部麦克风和至少一个内部麦克风记录的声音来执行主动降噪的数字有源降噪单元(ANR)。 有源降噪单元(ANR)包括分析单元(AU),用于分析由外部麦克风和内部麦克风记录的声音并确定记录声音的信号类型。 有源降噪单元还包括多个信号处理单元(SVE1-SVEn),每个信号处理单元被设计为对信号类型执行有源降噪。 分析单元(AU)基于对所记录的声音执行的分析来选择用于执行降噪步骤的信号处理单元(SVE1-SVEn)中的至少一个。

    • A transmitter for a wireless audio transmission system has at least one analogue/digital conversion unit for the analogue/digital conversion of the analogue audio signals to be transmitted, at least one digital signal processing unit with compressing/encoding means for compressing and encoding the digitised signals to be transmitted, a digital/analogue conversion unit for the digital/analogue conversion of the digital output signals from the digital signal processing unit into analogue signals, and a transmission unit for wirelessly transmitting the output signals from the analogue/digital conversion unit. Also disclosed is a receiver for a wireless audio transmission system having a reception unit for receiving wirelessly transmitted analogue H.F. signals, an intermediate frequency unit for mixing the H.F. signals into intermediate frequency signals, at least one analogue/digital conversion unit for the analogue/digital conversion of the wirelessly received signals, at least one digital signal processing unit with expanding/decoding means for expanding and decoding the signals digitised by the at least one analogue/digital conversion unit, and at least one digital/analogue conversion unit for converting the digital output signals from the digital signal processing unit into analogue signals.
