英国的新研究发现，在控制新冠病毒传播这件事上，音量很关键。相比大喊大叫和高声唱歌，轻声讲话和唱歌产生的气溶胶总量要低得多，从而能降低新冠病毒传播风险。 Photo by Alyssa Yung on Unsplash Sing softly and don’t shout to reduce the risk of Covid-19 spread, new research suggests, offering a ray of hope for musicians who have been restricted from performing in public. 新研究指出，轻声歌唱、不喊叫可以降低新冠病毒传播风险，这给那些被限制在公共场合表演的音乐家带来了一丝希望。 Music makers have been hit hard by the coronavirus pandemic, with singing, as well as playing of woodwind and brass instruments deemed to be a potential high risk for spreading the disease – a concern fuelled by outbreaks in choirs. 音乐家受疫情打击很严重，因为演唱以及吹奏木管和铜管乐器被视为传播新冠肺炎的潜在高危因素，合唱团暴发的聚集性病例加剧了这一担忧。 But the research offers hope to performers keen to get back on stage as soon as possible. 但是这项研究为那些想尽快回到舞台的表演者带来了希望。 "It is not about the vocalisation – whether it’s singing or speaking – it is about the volume,” said Jonathan Reid, a professor of physical chemistry at the University of Bristol and a co-author of the research. “Just by singing a little bit more softly you really reduce the risk.” |
