Although the spinning cycle is the noisiest, the amount of noise the pump makes is the cause for many users’ complaints. In an attempt to reduce the noise emitted when a washing machine is pumping out, an experimental study was performed. First, the measurement of the sound pressure allowed us to identify the main sources of noise as the electric motor and the vibration of the cabinet. Next, a detailed analysis based on the measurement of the vibration of the cabinet provided information about the predominant radiating panels. It was also inferred that the electromagnetic noise is drowned out by the structure-borne noise. Finally, several proposals to diminish the sound power were analyzed, and a reduction of 3 dBA was achieved by decreasing the contact zone of the pump with the kick plate. 000032160 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000032160 592__ $$a0.238$$b2015 000032160 593__ $$aEngineering (miscellaneous)$$c2015$$dQ2 000032160 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000032160 700__ $$0(orcid)0000-0003-3909-5599$$aSánchez-Tabuenca, B.$$uUniversidad de Zaragoza 000032160 7102_ $$15004$$2545$$aUniversidad de Zaragoza$$bDpto.
