介绍了温湿度可控的空调机噪声测试试验室的声学设计。该试验室四壁及顶部采用平面吸声层处理,空调送回风管道中采用迷宫式结构,其隔板表面做成尖劈状,低频吸声效果好;试验室隔声内门外门采用复合型壁板,内充玻璃棉,吸声层内再夹一层 NFC 板。试验室声学效果达到了预期的要求。 The acoustic design of the air conditioner noise test laboratory with controllable temperature and humidity was introduced. The lab walls and the top are treated with a flat sound-absorbing layer. The labyrinth structure is used in the return ducts of the air-conditioning. The diaphragm surface is made of a sharp cusp and the low-frequency sound absorption effect is good. The laboratory sound insulation inner door is used. Composite wall panel, filled with glass wool, and a layer of NFC board in the sound absorption layer. The laboratory acoustics achieved the expected requirements.
