Core Viewpoint - The implementation of the "Residential Project Standards" on May 1 has led to a significant upgrade in industry standards, particularly focusing on sound insulation performance, creating new opportunities for the construction of soundproof residential buildings [1][2] Group 1: Industry Standards and Innovations - The new standards require systematic sound insulation performance, prompting companies like Huntsman to introduce innovative solutions such as the SILENTANE acoustic system [1] - Huntsman's polyurethane damping elastomer, with over 20 years of mature technology, is widely applied in construction, high-speed rail, and automotive sound insulation, highlighting its effectiveness in the industry [1] Group 2: Product Features and Market Impact - Huntsman has launched an integrated system for floating floor insulation and soundproofing, utilizing high-performance polyurethane elastomers combined with porous fiber materials, which effectively suppresses low-frequency solid sound transmission [2] - This solution meets the new standard's requirement for impact sound levels to be less than or equal to 65 decibels, with the capability to achieve performance below 55 decibels, setting a new benchmark in the industry [2] - The system has been successfully applied in residential projects in Shanghai and has received certification from the UK’s Robust Details, providing a replicable technical model for the industry [2]

央广网北京4月30日消息（记者王泽华）据中央广播电视总台中国之声《新闻纵横》报道，每年4月 的最后一个星期三，是国际噪声关注日。噪声，对听力、睡眠、心血管、胃肠道、心情以及心理健康均 有不同程度的影响，近年来愈发受人关注。国家标准《住宅项目规范》5月1日起正式施行，新规范提高 了墙体和楼板的隔声性能要求，基本做到与国际水平接轨，能大幅减少噪声干扰问题。 隔壁吵闹、楼上跺脚、车流呼啸、下水干扰，住宅中可能出现的噪声多种多样。你是否想过它们的 来源，以及如何对症下药？不同类型的噪声，分别对应着怎样的分贝数，又是否超标？采用哪些手段， 可以满足新规范对新建住宅隔声性能的要求？既有住宅改造，又有哪些好办法？ 窗外的车流声、下水管道声、隔壁高声说话、楼上挪动桌椅板凳，乃至电梯、水泵等建筑设备运转 产生的噪声对生活的影响，大家或许多少都体验过。住宅内的噪声，一般来自哪些方面？《住宅项目规 范》编制组成员、中国建研院建科环能科技有限公司声环境研究中心主任闫国军介绍，这些噪声从来源 上，一般分为两大类：一类是建筑外部声源传入建筑内的噪声，另外一类是建筑内部人员活动或设备运 行产生的噪声。 闫国军说："对于新建住宅，为了满足新 ...
