Abstract: Starts from the principle of aerodynamic noise generation of range hoods, introduces the main causes of aerodynamic noise and the main solutions. The article summarizes the main noise sources of range hoods in the development process of range hoods, and how to judge the noise sources by finite element method. Computer simulation to judge the noise problem can avoid many design defects in the early stage of product development, reducing the time cost and capital cost of repeated proofing and trial production. The content summarized in the article provides a reference method for the subsequent development of range hoods and the solution of noise problems, it also provides ideas for solving noise problems for range hood developers.

Key words: Range hood, Health, Aerodynamic noise, Simulation
