Advantages of active silencer system (ANC)
Previous measurements showed that the active silencer allows the efficient reduction of low frequency noise components in the exhaustion section of cogeneration units by up to 25 dB. In contrast to conventional passiv systems of silencers and muffler, the ANC system requires considerably less installation space.
The underlying digital signal processing makes sure that the anti-noise system continuously automatically adapts to noise emitted by the cogeneration unit. In contrast to passive resonance mufflers which acoustic efficiency strongly depends on the temperature of the flowing medium, with the active silencer garanties a reliable noise reduction is guaranteed at any time.
