Abstract

Road traffic noise represents a major environmental challenge in densely populated urban areas, prompting the widespread implementation of noise barriers and tunnels as key mitigation measures. This study provides a comprehensive review of domestic and international regulations, classification systems, and recent research trends related to these noise control structures. Noise barriers are generally categorized as sound-absorbing, reflective, or tunnel-type, each exhibiting distinct material compositions, structural features, and performance characteristics. Recent Korean studies have emphasized multifunctional approaches, such as improved sound absorption standards, integration of photovoltaic modules into transparent barriers, and hybrid systems combining noise reduction with dust filtration and active noise control. In contrast, international research primarily focuses on standardized performance evaluation, structural safety, and eco-friendly design principles. Representative examples include field tests of aluminum foam panels, the application of tilting mechanisms to mitigate wind loads, and the establishment of comprehensive design and management guidelines in Europe. While Korea demonstrates technological innovation and multifunctional development, challenges remain in large-scale validation, long-term durability, and fire safety—particularly for tunnel-type barriers. International efforts, though systematic and standardized, are relatively conservative in adopting multifunctional systems. Notably, fire safety considerations are insufficiently addressed in both domestic and international contexts. Future research should therefore integrate multifunctionality with structural resilience by prioritizing non-combustible materials, fire-resistant designs, and sustainable long-term performance, thereby advancing noise barriers as safe, durable, and sustainable components of urban infrastructure.
