131 Noise Reduction of Vacuum Cleaner with the Method of Transfer Path Analysis by Actual Measurement Data

Abstract

The method of transfer path analysis by actual measurement data was applied to structure-borne sound of vacuum cleaner. The contribution of each transfer path was obtained by using the transfer path model consist of three layers, and the path with large contribution was identified. And, the noise reduction of the structure-borne sound about 5dB was achieved by giving the vibration insulation structure to the transfer path with large contribution.
