Abstract
A sound barrier is a wall that serves to provide a high-quality hearing environment to people living in a nearby living area by blocking noise generated from a car-only road. The Sound barrier can be divided into reflective, soundabsorbing, interference, and resonance types according to the soundproofing method. There are transparent, metal, non-metallic, vegetation, and solar panel types depending on the soundproofing material. Among the sound barrier, the reflective type is mainly installed in terms of cost, and the transparent type, wood material or steel material sound barrier is mainly used for aesthetics. In this paper, the sound insulation level of the Flat Type of Transparent Sound Barrier was tested among the reflective sound barriers currently used mainly for automobile roads. Among the interference type sound barriers, Steel Material Interference Type Sound Barriers and Wood Material Interference Type Sound Barriers were tested to determine the most efficient sound barriers. Through this study, it is intended to help select and install appropriate sound barriers for urban aesthetics as well as soundproofing efficiency between automobile roads and living areas. In addition, it suggests the need for research on soundproofing environments in various ways, going beyond soundproofing research between automobile-only roads and living areas, which rely only on sound barrier Future.
