    • Evaluation of the effectiveness of control sources’ interval on active noise control performance 

      Sohrabi, Shahin; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (Sociedad Española de Acústica (SEA), 2019)
      Conference report
      Open Access
      Amongst many important factors that affect the performance of active noise barrier, namely, the location of error microphones, and secondary sources, the intervals of adjacent error microphones and secondary sources, etc. ...
    • Investigate the effect of the active noise barrier on the reduction of noise level at the shadow zone and the neighboring building

      Barriers are among the most widely used strategy to control the ambient noise in the urban areas. However, the previous studies approve the inefficiency of the barriers to degrade low-frequency spectra noise. The technique ...
    • Numerical study of an active noise barrier

      A numerical study was performed to find the best position for error sensors and secondary sources of an active noise barrier. In this paper, a numerical study has been done, using MacDonald's solution, to calculate diffracted ...
    • Revision of cancellation at the edge approach for active noise barrier 

      Sohrabi, Shahin; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (2020)
      Conference report
      Restricted access - publisher's policy
      In most of the investigations, the active noise barriers are configured placing both secondary sources and error sensors close to the edge of barriers, but it is unclear how far is this approach from the maximum theoretical ...
    • Suitability of Active Noise Barriers for Construction Sites 

      Sohrabi, Shahin; Pàmies Gómez, Teresa; Romeu Garbí, Jordi (2020-09-04)
      Article
      Open Access
      Barriers are increasingly used to protect the pedestrian and neighboring buildings from construction noise activities. This study aims to investigate the suitability of applying active noise control on barriers in a ...
