Applications of Modal Techniques to Noise Control of Hermetic Refrigeration Compressors

That there exists interaction between vibration and structure-borne or structurally radiated sound is generally recognized. However, it is often difficult to predict the complex interactions between excitation forces, structural responses and the generation of sound. This paper will discuss such interaction especially in light of modal characterizations of the structural vibrations. In addition, a case history of application of these techniques to control noise emissions from a hermetic reciprocating compressor is discussed.
