  如何判断铝合金隔声屏障能降多少分贝

  在选购铝合金隔声屏障鼎盛彩票app的时候,如何判断铝合金隔声屏障的隔音降噪效果,而且铝合金隔声屏障能降多少分贝,这是大家关心的问题!下面安平喆奥小编为大家介绍下关于隔声屏障方面的知识,希望对大家选购隔声屏障有所帮助!铝合金隔声屏障的声学原理是声音在传播过程中遇到隔声屏障时,会发生反射、投射和绕射三种现象,通常情况下,直线传播的声波都可以被声屏障阻隔、反射;可穿透的声波仅限于一些低频的长波,而绕射的声波也会衰减。在声学环境里,声屏障的隔声效果可以用减噪量来表示。在声源和接受点之间插入隔声屏障,且屏障长度无限长,那么声波只能从屏障上方绕射,临近的接收点则处在声影区,这部分区域里,噪声明显衰弱,从而实现隔声屏障的减噪效果。

  2,高速公路声屏障立柱一般选用较多的是125H型钢立柱或100H型钢立柱。另外在板厚的选择上,较多的为0.8、1.0、1.2的板,在屏体厚度选用较多的一般为10公分厚。同时也要确定所建地区适合弧形隔音屏障或者是直立型隔音屏障,做到因地制宜。今天跟大家推荐的都是比较常用的,没有包含所有规格,毕竟声屏障为定制产品,都是要根据具体情况来定。
