Chinese researchers appear to have solved the critical 'tunnel boom' problem plaguing ultra-high-speed maglev trains capable of 600km/h (370mph). By implementing innovative porous soundproofing buffers at tunnel entrances, shock waves causing structural damage and noise pollution are reduced by up to 96%, paving the way for practical implementation of next-generation magnetic levitation networks. This breakthrough addresses a fundamental physics challenge that threatened to derail maglev's potential for revolutionizing long-distance travel.
