Effect of Noise and Temperature on the Performance of Ferro-Tunnel FET

Study on measurement and simulation of noise field between long tunnel and underground interchange

“…Furthermore, the new "Highway Tunnel Design Code" does not have provisions for acoustic design of tunnels with structures similar to underground interchanges [25] . However, as people's environmental requirements continue to increase, the issue of noise in long tunnels and underground interchanges has gradually received attention and will have more and more noise reduction design and renovation considerations for urban roads passing through tunnels [26,27] . This study aims to establish a complete application from the analysis of the sound field characteristics in long tunnels and underground interchanges to the design of an active noise reduction system, achieving the goal of standardizing and systematizing noise characteristic measurement and active noise reduction system design.…”
