Abstract：To address the challenge of predicting the noise of range hoods,a research method combining experiments and simulations is proposed.Taking a top-suction range hood as the research object,three different combinations of air cabinets and impellers are selected for the study.Noise measurements under different operating conditions are carried out within the rotational speed range of 900 r/min～1600 r/min to collect noise data.The analysis reveals that the air volume Q,power P,and operating noise Lw satisfy a multivariate logarithmic function relationship,and the final relational expression Lw=k1+k2·lg(Pk3·Qk4)is proposed.
