- W2376586668 abstract "Based on the basic theory of ANC within the enclosed space,this paper models the enclosed space with the COMSOL software,and presents the simulation and analysis effects of noise reduction which is derived from the numbers and location of the secondary noise resources.The results show that: It has a evident noise reduction when the secondary noise resources located at the space spots which are odd times of half-wavelength away from the primary noise resource.When Single secondary noise resource is closer to the target sound field,the whole sound field has a evident noise reduction;when double and treble secondary noise resources are located,evevy resource maintains an appropriate distance close to the target area,the noise reduction is evident and the sound pressure level can be reduced to 60dB or much lower." @default.
