摘要
隔声对于声频工程的降噪起着关键的作用,隔声分为空气声隔声与撞击声隔声。对单层墙体与双层墙体的隔声量作了比较,分析了轻质隔声材料与构造与重质隔声材料与构造在隔声性能上的差异,说明了撞击声隔声的方法与特点。
Sound insulation plays a key role in noise reduction of audio engineering.Sound insulation can be divided into air sound insulation and impact sound insulation.The sound insulation capacity of single-layer wall and double-layer wall is compared.The difference of sound insulation performance between light-weight and heavy-weight materials and structures is analyzed.The method and characteristics of impact sound insulation are explained.
