该研究的合著者、布里斯托大学物理化学系教授乔纳森·里德说:“无论是唱歌还是说话,都与发声方式无关,而是与音量有关。唱歌时稍微轻柔一些就能降低传播风险。”
In a study that has yet to be peer-reviewed, the team report how they asked 25 professional singers to breathe, speak, cough and sing into funnels. They then measured the mass of tiny droplets suspended in the air, known as aerosols, that were produced. The experiments were set up in an orthopaedic operating theatre, a setting chosen for its lack of background aerosols.
在一项尚未经过同行评议的研究中,研究团队请25名专业歌手对着漏斗状的器具呼吸、讲话、咳嗽和唱歌。然后他们测量了由此产生的气溶胶(在空气中悬浮的微小飞沫)的总量。实验在一个骨科手术室进行,选择这个环境是因为这里的气溶胶较少。
While one route by which Covid-19 spreads is via big droplets, largely produced when someone coughs and which fall to the ground within a couple of metres, Reid said aerosols were another possible route, noting such tiny droplets can linger in the air.
新冠病毒传播的一条路径是通过飞沫,大多是在某人咳嗽时产生,在一两米的距离内会落到地面。里德表示,气溶胶是另外一条可能的传播路径,他指出微小的飞沫会悬浮在空气中。
The team found the results of their study varied across participants, however at the lowest volume singing and speaking generated a similar mass of aerosols as breathing.
