The evaluation of Propeller Radiated Noise (PRN) has always been part of the assessment of internal noise, vibration, and habitability. In recent years, PRN has become a focal point for international regulatory efforts to reduce Underwater Radiated Noise (URN). While difficult to quantify analytically, there are ways to easily characterize PRN as well as common sense practices that can help designers reduce both internal and underwater PRN. This half hour webinar with Don MacPherson will introduce key principles of PRN, universal ways to reduce and mitigate PRN, and the hydroacoustic evaluation utility in NavCad that can be used to provide measures of influence for different mitigation strategies.
