Study on the Effectiveness of Monte Carlo Filtering when Correcting Negative SEA Loss Factors [PDF]

open access: yesArchives 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.
