The wall thickness of these areas is not uniform, and the size of the common road sound insulation board is fixed. This mismatch brings challenges to installation and use. When installing, it is easy to have gaps or be not firm, which affects the sound insulation effect and has safety hazards. In addition, most sound insulation boards are single-layer structures, and the composition of traffic noise is complex and the frequency is various. The single-layer sound insulation board has limited blocking and absorbing capacity, resulting in that the surrounding environment is still disturbed by a large amount of noise. This cannot meet the demand of residents for quiet environment, and does not meet the increasingly strict environmental noise control standard, which needs to be improved.
