A noise reducing sound reproduction system comprising: a loudspeaker that is connected to a loudspeaker input path; a microphone that is acoustically coupled to the loudspeaker via a secondary path and connected to a microphone output path; a first subtractor that is connected downstream of the microphone output path and a first useful-signal path; an active noise reduction filter that is connected downstream of the first subtractor; and a second subtractor that is connected downstream of the active noise reduction filter, downstream of a second useful-signal path, and upstream of the loudspeaker input path, wherein: the secondary path has a secondary path transfer characteristic (S(z)); both useful-signal paths are supplied with a useful signal (x[n]) to be reproduced; and at least one of the useful-signal paths comprises one or more spectrum shaping filters (10, 11, 18, 19, 20), wherein at least one of the spectrum shaping filters has a transfer characteristic that models the secondary path transfer characteristic (S(z)); the first useful-signal path comprises the at least one spectrum shaping filter and the at least one spectrum shaping filter that models the secondary path transfer characteristic linearizes a microphone signal (y[n]) on the microphone output path with regard to the useful signal (x[n]); the at least one spectrum shaping filter that models the secondary path transfer characteristic comprises at least two sub-filters (18, 19); and one of the sub-filters (18, 19) of the at least one spectrum shaping filter that models the secondary path transfer characteristic is a treble cut shelving filter. a loudspeaker that is connected to a loudspeaker input path; a microphone that is acoustically coupled to the loudspeaker via a secondary path and connected to a microphone output path; a first subtractor that is connected downstream of the microphone output path and a first useful-signal path; an active noise reduction filter that is connected downstream of the first subtractor; and a second subtractor that is connected downstream of the active noise reduction filter, downstream of a second useful-signal path, and upstream of the loudspeaker input path, wherein: the secondary path has a secondary path transfer characteristic (S(z)); both useful-signal paths are supplied with a useful signal (x[n]) to be reproduced; and at least one of the useful-signal paths comprises one or more spectrum shaping filters (10, 11, 18, 19, 20), wherein at least one of the spectrum shaping filters has a transfer characteristic that models the secondary path transfer characteristic (S(z)); the first useful-signal path comprises the at least one spectrum shaping filter and the at least one spectrum shaping filter that models the secondary path transfer characteristic linearizes a microphone signal (y[n]) on the microphone output path with regard to the useful signal (x[n]); the at least one spectrum shaping filter that models the secondary path transfer characteristic comprises at least two sub-filters (18, 19); and one of the sub-filters (18, 19) of the at least one spectrum shaping filter that models the secondary path transfer characteristic is a treble cut shelving filter. the secondary path has a secondary path transfer characteristic (S(z)); both useful-signal paths are supplied with a useful signal (x[n]) to be reproduced; and at least one of the useful-signal paths comprises one or more spectrum shaping filters (10, 11, 18, 19, 20), wherein at least one of the spectrum shaping filters has a transfer characteristic that models the secondary path transfer characteristic (S(z)); the first useful-signal path comprises the at least one spectrum shaping filter and the at least one spectrum shaping filter that models the secondary path transfer characteristic linearizes a microphone signal (y[n]) on the microphone output path with regard to the useful signal (x[n]); the at least one spectrum shaping filter that models the secondary path transfer characteristic comprises at least two sub-filters (18, 19); and one of the sub-filters (18, 19) of the at least one spectrum shaping filter that models the secondary path transfer characteristic is a treble cut shelving filter.
