Glass is a sound-proof material, but researchers at the Hong Kong University of Science and Technology (HKUST) have discovered a way which allows sound transmission for glass, opening a new horizon for the potential development of smart phones and other electronic devices that can function under water, while also offering greater flexibility to building design.
Using the theory of local resonance, a research team led by Prof. WEN Weijia from the Department of Physics has found that by crafting a structured pattern of openings in between glass panes, the sound waves’ mode of vibration will be altered, allowing sound to pass through. Read More...
