Abstract

The invention discloses a ventilating fully-closed sound barrier. The ventilating fully-closed sound barrier comprises a door-type steel frame, upright acoustical boards are arranged on the outer sideof the door-type steel frame in the vertical direction, arc acoustical boards are arranged at the corners of the two sides of the upper portion of the door-type steel frame, and a top transparent sound insulation acrylic board is arranged between the arc acoustical boards; an air outlet is formed in the middle of the top transparent sound insulation acrylic board, a ventilation acoustical louveris mounted at the air outlet, supporting springs are connected between the arc acoustical boards and the upright acoustical boards, and the upright acoustical boards, the arc acoustical boards, the top transparent sound insulation acrylic board and the door-type steel frame are fixed through connection boards. According to the ventilating fully-closed sound barrier, through the arrangement of thetop ventilation acoustical louver and the upper supporting springs, the internal and external ventilation effects of the sound barrier can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of noise control equipment, in particular to a ventilated fully enclosed sound barrier. Background technique [0002] While highways and railways bring convenience to people's travel, they also bring noise pollution to residents along the lines. For this reason, current highways usually set up soundproof walls along residential areas to reduce the impact of noise on residents along the lines. The vertical sound barrier is affected by sound diffraction, which greatly reduces the noise reduction effect of the sound barrier, and the sound shadow area is significantly reduced. The fully enclosed sound barrier can effectively solve the problem of sound diffraction affecting the noise reduction effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ventilated fully enclosed sound barrier that can effectively reduce noise in residential areas.
