Popis: Transfer paths are complex and difficult to analyze. The characteristics of vibration and noise transmission are also complex and various vibrations and noise sources are correlated. In this study, we experimentally investigated the noise and vibration transmission mechanisms of a drum-type washing machine. In addition, we analyzed the transfer path and coherence using the multi-dimensional spectral analysis approach designed to remove correlations by implementing coherence and frequency response functions to the operating status. Finally, we estimated the contributions of individual components to the output noise radiated by structural vibrations.
