This invention introduces a transparent, tunable micro-perforated metasurface capable of absorbing low-to-mid frequency sounds, offering a solution to reduce noise pollution in urban areas. Its design consists of adjustable micro-perforated holes for real-time sound absorption optimization, making it suitable as a smart sound barrier along train tracks, bus stop linkways, and for window installations to enhance indoor noise protection. The technology combines ease of use with a wide tuning range, promising effective broadband noise attenuation. This versatile approach offers a thin, lightweight solution that can fit into narrow spaces, providing a significant advantage in densely populated urban settings.
