| Abstract: | Among the noise control technologies,the most cost effective means of noise reduction for small mechanical equipment is to use sound insulation equipment to cut off the transmission paths of the noise source.Based on the above requirements,the principle of acoustic enclosure was analyzed,the performance of acoustic enclosure was evaluated,and the phononic crystal acoustic enclosure was designed.The structure,external dimensions and functional modules of the phononic crystal acoustic enclosure were introduced,and the simulation analysis was carried out to confirm the designed noise reduction requirements of the acoustic enclosure. |
