Abstract: Due to the pressure of market competition and other reasons, the air volume of the range hood is getting larger and larger, and the noise problem is becoming increasingly severe, and it is difficult to make breakthrough progress on the noise reduction effect through traditional technologies such as structural optimization. Under the background of the rapid development of intelligent technology, the use of intelligent monitoring perception and logical control, intelligent technology not only improves the convenience and comfort of the range hood, but actually has significant effect on in-depth noise reduction. Select the most intelligent function of the intelligent range hood, and deeply study and demonstrate the noise reduction effect under the intelligent function from the perspective of reducing the time proportion of the high noise area.

Key words: Intelligent, Range hood, Noise
