This paper conducts source identification method by use of phase reference
spectrum and transfer path analysis.
First, in the case of source identification, the transfer function between the
cabinet and the motor through FEM and the measured response from the
surface of the cabinet is used. The analysis of the radiation noise from the
identified exciting force has been investigated. The comparison between the
predicted SPL and the measured SPL at 1m apart from the front side of the
washing machine showed good tendency.
Second, in the case of transfer path analysis, calculate the transmissibility
function between input and output which is selected the input and output in
consideration of the washing machine noise induced factors. As a result of a
transfer path analysis at 1380, it could be confirmed to have the value of the
maximum contribution from the right side of the cabinet.
