前言无论在学校、工作场所或家庭环境中,有害噪音对学习、工作和生活的影响都很大。混凝土砌体墙通常用于隔离和驱散(反射)噪音。混凝土砌体采用两种方式提供优越的噪音管控作用,首先混凝土砌体能有效地阻断通过空气介质传递过来的、声频范围宽广的噪音传递;其次混凝土砌体能有效地吸收噪音,以降低穿透墙体的噪音强度。正是由于混凝土砌体的这些功能,使它被广泛地应用在围墙、酒店建筑的分户隔
Preface Noise, harmful to learning, working and living, whether in school, at work or in a home setting, can be significant. Concrete masonry walls are commonly used to isolate and disperse (reflect) noise. Concrete masonry provides superior noise management and control in two ways. First, concrete masonry can effectively block the transmission of a wide range of audible noise through the air medium. Secondly, concrete masonry can effectively absorb the noise to reduce wear Through the wall of the noise intensity. It is because of these features of concrete masonry that it is widely used in the wall,
