É estudada a aplicação de um sistema de controle ativo de ruído em um duto de comprimento finito. Os sistemas de entrada única e saída propostos anteriormente são inadequados neste caso, porque a reflexão nos terminais degrada o desempenho e/ou filtros de resposta de impulso infinito são necessários para um cancelamento de ruído perfeito. Neste artigo, propomos um sistema de entrada única e saída aplicável a dutos de comprimento finito, que teoricamente alcança um cancelamento de ruído perfeito usando apenas filtros de resposta a impulso finito. Os comprimentos de derivação dos filtros são tão curtos quanto os atrasos entre o sensor de referência e a fonte secundária. Uma implementação útil do sistema proposto também é discutida.

Abstract: The application of an active noise control system in a finite-length duct is studied. Previously proposed single-input-single-output systems are inappropriate in this case, because reflection at the terminals degrades the performance, and/or infinite-impulse-response filters are required for perfect noise cancellation. In this paper, we propose a single-input-single-output system applicable to finite-length ducts, which theoretically achieves perfect noise cancellation while using finite-impulse-response filters only. The tap lengths of the filters are as short as the delays between the reference sensor and the secondary source. A useful implementation of the proposed system is also discussed.
