消声器消声器muffler在进排气系统安装的降低气流噪声的装置。20世纪30年代，一些国家开始在通风管道上安装消声器。随着内燃机、汽车等大量使用，消声器技术迅速发展，消声理论也逐渐完善，消声效果日益提高。消声器主要有以下几种：①阻性消声器。把吸声材料固定在气流管道内壁，或按一定排列方式固定在管道中，利用吸声材料降低噪声，在中高频范围内有较好的消声效果。有片式、插管式、圆管式、室式、蜂窝式、菱形、正弦波形等消声器。主要用于风机进出口管道。②抗性消声器，又称声学滤波器。靠控制声抗，使某些频率的噪声反射回声源，达到消声的目的。适用于消除低中频噪声，如汽车、内燃机、无声手枪等的噪声。③阻抗复合消声器。将阻性和抗性恰当地组合起来，就是阻抗复合消声器，可在宽频范围内获得较好的消声效果。常用的有阻-扩复合式、阻-共复合式、阻-共-扩复合式消声器等。④微穿孔板消声器。用微穿孔吸声结构制作的纯金属消声器。能在较宽频率范围内消除气流噪声，具有耐高温、耐油污、耐蒸汽和抗腐蚀等性能。其他形式的消声器有：耗散型消声器（依靠气流同消声元件的摩擦、弯折、扩散等作用，使气体压强和速度降低)，电子消声器（利用电子线路和扩声设备产生与噪声的相位相反的声音，来抵消原有噪声），多孔扩散消声器（气流通过多孔装置扩散后速度或驻点压强降低）等。安装在中国江苏望亭发电厂房顶上的小孔消声器消声器性能主要以下列指标评价：①消声性能。以消声值、消声系数和消声指数大小来评价，其值越大越好。②空气动力性能。以压力损失、阻力系数大小来评价，其值越小越好。③结构性能。几何尺寸越小、寿命越长、价格越低，则性能越好。
