  5. 24. Implementation Considerations for Active Noise Control in Ventilation Systems

    Kandidat-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Författare :Marcus Asteborg; Niklas Svanberg; [2006]
    Nyckelord :Active Noise Control; Adaptive Signal Processing; Analog Filters; Digital Signal Processor;

    Sammanfattning : The most common method to attenuate noise in ventilation systems today is passive silencers. For these to efficiently attenuate frequencies below 400 Hz such silencers need to be large and a more neat solution to attenuate low frequencies is to use active noise control (ANC). LÄS MER
