Study on the Effectiveness of Monte Carlo Filtering when Correcting Negative SEA Loss Factors [PDF]
Archives of Acoustics, 2023 The power injection method (PIM) is an experimental method used to identify the statistical energy analysis (SEA) parameters (called loss factors – LFs) of a vibroacoustic system. By definition, LFs are positive real numbers.
