Acoustic noise source identification: a study on a household refrigerator during the starting of a reciprocating compressor

This thesis deals with the analysis of the sound radiated by a household refrigerator when a reciprocating compressor starts its operation. The study was developed based on theoretical analysis by means of numerical simulations and on a phenomenology basis by means of experimental tests performed on...
