Acoustic analysis of the drainage cycle in a washing machine

Washing machine manufacturers are working towards producing quieter appliances as many people consider noise emission a key factor when buying. 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 e...
