Abstract

The transparent sound absorption and insulation board for the sound barrier comprises a sound absorption unit, side frames, a bottom frame and a sound insulation unit, the side frames are arranged on the two sides of the sound insulation unit, the bottom frame is arranged at the lower end of the sound insulation unit, and the sound absorption unit is arranged at the upper end of the sound insulation unit. The sound absorption unit comprises a sound absorption panel, a sound absorption back plate and a sound absorption material, the sound absorption material is arranged in the sound absorption back plate, the sound absorption panel is arranged on one side of the sound absorption back plate, the sound insulation unit comprises a transparent plate, a micro-perforated plate, a connecting piece and a cavity, the micro-perforated plate is arranged on one side of the transparent plate, and a cavity is formed between the transparent plate and the micro-perforated plate. According to the transparent sound absorption and insulation board for the sound barrier, on the basis of meeting the light transmission and sound insulation effects of a traditional sound barrier, the transparent board unit for the sound barrier has a good noise reduction effect, the overall insertion loss of the sound barrier is increased, and the influence on residents is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of noise control, in particular to a transparent sound-absorbing and sound-insulating board for a sound barrier. Background technique [0002] In recent years, with the continuous deepening of the country's construction of a better life for the people, the continuous increase in the supervision of environmental issues and the continuous improvement of residents' awareness of environmental protection, various environmental issues have been paid more and more attention. For urban residents, traffic noise is the main influencing factor. At present, the most used method to solve the problem of traffic noise is to set up sound barriers on both sides of the road. This method can effectively reduce the impact of traffic noise on residents' lives. The sound barrier is a barrier set up between the noise source and the receiving point to block the transmission of noise. According to its function type, the sound barrie...
