摘要
通过Soundplan软件建模,分析比较了户内式变电站的主变室设计中,不同通风散热设计方式和吸声材料的隔声降噪效果。研究结果表明,采用通风方式三效果最好,可降低噪声10.5~16.6dB(A),采用声学材料(50mm)效果最好,可降低噪声9.8~10.4dB(A)。
Based on the model of Soundplan, the influences of different styles of ventilation and heat dispersion and different sound absorption materiales on the noise emission are analyzed. The research results show the third is best and can reduce noise by 10.5 - 16.6 dB(A) ; the acoustic coating 50 mm is best and can reduce noise by 9.8 - 10.4 dB(A).
