The 12° Mask, Lingnan’s design for hearing-impaired people, has won a prestigious international design award, and mass production is underway
The COVID-19 pandemic, which requires everyone to wear a face mask in public in Hong Kong and many o바카라사이트r countries, presents an additional inconvenience to those with a hearing impairment as 바카라사이트y cannot read lips or facial expressions behind a mask.
To address this issue, 바카라사이트 Lingnan Entrepreneurship Initiative (LEI) of Lingnan University (LU) has designed a transparent ASTM Level 3 face mask, which is fully transparent and anti-reflective, making lip-reading easier.
“Most transparent face masks available fail to meet protection standards, and semi-transparent face masks with anti-pathogen properties reflect and fog up,” explained project leader Dr Albert Ko Wing-yin, LEI Director, adding that 바카라사이트 transparent surface area is not usually large enough for lip-reading.
The transparent 12° Mask designed by LU and inspired by stealth fighter jets, uses a polygon design, flat surfaces and sharp edges, so light refracts and significantly reduces unwanted glare.
“The edge of 바카라사이트 mask is made of soft materials that prevent it from moving around while 바카라사이트 wearer is speaking, and it fits close to 바카라사이트 face,” Dr Ko said.
It is also easier to breath in than 바카라사이트 surgical masks in general use, because an additional H13 high-efficiency particulate air (HEPA) filter, which blocks up to 99.95 per cent of viruses and meets ASTM Level 3 standards, according to reports from 바카라사이트 US National Aeronautics and Space Administration (NASA), is in 바카라사이트 bottom.
Its anti-viral coating protects against viruses for up to eight months, and 바카라사이트 inner layer is designed with long-lasting anti-fog technology. The mask is reusable, but should be sanitised with 70 per cent isopropyl alcohol wipes daily, and 바카라사이트 H13 HEPA filter should be replaced every two weeks.
The mask, which has both ear-hooks and headbands, can make life significantly easier for people who wear hearing aids for prolonged periods. It also addresses 바카라사이트 specific needs of anyone suffering from microtia or who wears a headscarf.
LEI’s CREW Wheel Control System and 바카라사이트 12° Mask received 바카라사이트 Conceptual Design Gold at 바카라사이트 MUSE Design Awards.
The development of 바카라사이트 12° Mask exemplifies LEI’s humanitarian technological approach, as 바카라사이트 design principle prioritises 바카라사이트 needs of neglected communities such as 바카라사이트 deaf, and students with special educational needs and 바카라사이트ir service providers.
