Upright sound barrier and top structure thereof
The invention discloses an upright sound barrier and a top structure thereof, which aims to improve the sound insulation and noise reduction effects of the sound barrier. Thus, on one hand, the top structure of the upright sound barrier comprises an outer cylinder and an inner cylinder, wherein the outer cylinder and the inner cylinder are coaxially arranged, both the outer cylinder and the inner cylinder are made of micro-perforated plates, an annular cavity is formed between the inner cylinder and the outer cylinder, and the outer cylinder, the inner cylinder and the annular cavity form a micro-perforated plate sound absorption structure; and a first sound insulation material layer which is used for axially separating the annular cavity halfway is vertically arranged in the inner cylinder, and a second sound insulation material layer which is used for axially separating an inner cavity of the inner cylinder halfway is vertically arranged in the inner cylinder.
本发明公开了一种直立声屏障及其顶部结构，旨在提升声屏障的隔声降噪效果。为此，本发明实施例一方面提供的直立声屏障顶部结构，包括同轴设置的外筒和内筒，所述外筒和所述内筒均由微穿孔板制作而成，所述内筒和所述外筒之间形成有一环形空腔，所述外筒、所述内筒和所述环形空腔构成一微穿孔板吸声结构；所述内筒内竖直设有一轴向对半分隔所述环形空腔的第一隔声材料层，所述内筒内竖直设有一轴向对半分隔其内腔的第二隔声材料层。
