长期以来，校园操场噪声与周边社区宁静需求的矛盾，似乎总是难以调和。针对这一难点和痛点，江苏 省南京市近日在多所学校试点"静音操场"改造项目，通过技术创新与精细化设计，取得显著降噪效果， 赢得了当地群众的普遍称赞。 南京市经过深入调研，针对包括鼓楼区第一中心小学、洪武北路小学在内的7所广播噪声扰民问题尤为 突出的学校，打出了一套"核心技术+量化设计"的组合拳。引入"相控阵波束成形技术"，通过智能算法 协同多组扬声器，声波被精准聚焦投射到操场区域，使得音箱能播放教学所需的清晰音量，而传到周边 居民家中的声音则可低至日常交谈大小。 南京市的探索创新可供借鉴。相关学校应认真开展调研工作，弄清楚操场噪声来源、声源强度、传播路 径、影响范围，结合周边市民静音需求，制定学校"静音操场"改造方案。比如除了广播噪声外，一些学 校也存在球类撞击振动噪声，对此可选择具有减震功能和吸音性能优异的材料铺设操场，降低球类撞击 地面引发的冲击性振动噪声。同步加强校园绿化带和声屏障系统建设，进一步减轻振动噪声污染影响， 实现学生需求与居民安静环境的和谐共存。 ...
