A fully enclosed sound barrier, though primarily a special building for road noise control, also requires careful landscape design. The design should consider the overall landscape effect, aiming to minimize any significant negative impact on the local scenery, while meeting the primary sound insulation function of the barrier, ensuring normal road traffic, and avoiding excessive increase in the total investment. For traffic arteries in densely populated cities, it is recommended to consider using fully enclosed sound barriers in the future, which can greatly save land resources along the traffic arteries and meet the requirements of land intensification.
