无论是在家里或工作的办公室,烦人的噪声都可能让人分心。混凝土砌块(砖)墙体通常会用于隔离和驱散(反射)噪音,因为混凝土砌体是非常好的控制噪声传播的建筑材料。混凝土砌体对噪音的管控有两种途径:第一,能够有效地阻断频率宽广噪音的传播;第二,能够有效地吸收噪音,降低“穿透”墙体的噪音强度。这些性能使混凝土砌块(砖)砌体经常成功地用于住宅的分户墙、酒店的隔墙,甚至高速公路边的声屏障墙。声音传播等级(STC。也可简称传声等级)常用来 The annoying noises, whether at home or at work, can be distracting. Concrete block (brick) walls are often used to isolate and disperse (reflect) noises because concrete masonry is a very good building material for controlling noise propagation. Concrete masonry noise control in two ways: first, it can effectively block the spread of a wide frequency noise; second, can effectively absorb the noise and reduce the “penetration ” wall of the noise intensity. These properties make concrete block (brick) masonry often successful for residential decks, hotel divisions, and even highway sound barrier walls. Sound transmission level (STC. Also referred to as the sound level) commonly used
