Abstract
The invention relates to a hybrid silencer by which a passive absorber lining is combined with an active electroacoustic system such that the sound dissipation is increased by the impact of the active subsystem on the passive absorber lining in order to obtain an optimized conduit side acoustic impedance and thus enhanced sound dissipation in a wide frequency band, in particular at low frequencies.
