    • Active control of noise in ventilation ducts 

      Paurobally, Mohammad Roshun; Sassi, Sadok; Renno, Jamil ( Canadian Acoustical Association , 2019 , Conference Paper)
      Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ...

    • Numerical simulation of one-stage gearbox dynamics in the presence of simultaneous tooth cracks 

      Mohamed, Ahmed; Sassi, Sadok; Paurobally, Mohammad Roshun ( International Institute of Acoustics and Vibration, IIAV , 2017 , Conference Paper)
      Gears are vital components in various industrial machinery. Tooth fatigue crack is amongst the most common causes of gear failure. Early detection of tooth cracks is crucial for effective con-dition-based monitoring. This ...

    • Wireless active noise control results 

      Paurobally, Mohammad Roshun; Sassi, Sadok; Moses, Kosgei; Khadembashi, Daruosh ( International Institute of Acoustics and Vibrations , 2016 , Conference Paper)
      Active Noise Control (ANC) is used in controlling low frequency noise where passive control is ineffective. Most (ANC) systems use physical cables to connect various parts of the system for operation. This can be bulky and ...
