Sea for Predicting the Efficiency of Noise Reduction Solutions Applied to an Air Conditioner Unit

Nowadays aspiration for a better quality of life includes a growing demand for lower noise air conditioners. There consequently seems to be a need for tools that would help manufacturers to understand both the generation of noise in a device and its propagation to the surrounding medium. In the present paper, we propose a modelling tool for making a global diagnosis of the propagation of mechanical and acoustical waves inside and from an existing air conditioner. We also use that tool to try to foresee the efficiency of a noise reduction solution.
