First Claim
1. An earphone comprisinga first housing (LK, AK, IK) for receiving an electroacoustic reproduction transducer and a second housing (RK, AK, IK) for receiving an electroacoustic reproduction transducer (L),at least one outer microphone (M1) for recording outside sound,at least one inner microphone (M2) for recording sound in the region between an ear of a user and the first or second housings (LK, RK, AK, IK), anda digital active noise reduction unit (ANR) for performing active noise reduction based on the sound recorded by the at least one outer microphone and by the at least one inner microphone,wherein the noise reduction unit (ANR) has 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 and a plurality of signal processing units (SVE1-SVEn) which are respectively adapted to perform noise reduction for a signal type,wherein the analysis unit (AU) selects at least one of the signal processing units (SVE1-SVEn) for performing noise reduction based on the implemented analysis of the recorded sound.

Abstract
There is provided an earphone comprising a first housing (LK, AK, IK) for receiving an electroacoustic transducer and a second housing (RK, AK, IK) for receiving an electroacoustic reproduction transducer, at least one outer microphone (M1) for recording outside sound and at least one inner microphone (M2) for recording sound in the region between an ear of a user and the first and/or second housings (LK, RK, AK, IK). The earphone 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 by the at least one inner microphone. The noise reduction unit (ANR) has 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 noise reduction unit further comprises a plurality of signal processing units (SVE1-SVEn) which are respectively adapted 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 noise reduction based on the implemented analysis of the recorded sound.
