Abstract
The noise emitted by an electrical pump is mainly generated by different sources, (mechanic impats of rotor, fluid dynamic turbolences) but it is also affected by th structural response of each component of the pump. In this paper experimental results of the acoustic characterisation of an electrical pump is presented in order to point out the influence of different noise sources to the emitted noise power. Different techniques of investigations have been performed: measurements of the acoustic field are carried out and compared with vibration response of the pump. A parallel investigation of the thermograph radiation during the start up was also performed in order to a better understanding of the localisation on noise sources
