This review aims to analyze the effects of the pandemic on the world's sound environment.
The confinements associated with the pandemic led to a reduction in sound levels worldwide and a change in the perception of soundscapes in the absence of traffic noise and human-generated noise.
In response to the COVID-19 pandemic, many countries and regions around the world adopted a series of interventions in 2020 that have been referred to as "lockdown" or "confinement." These sets of restrictions had a clear and obvious consequence derived from the absence of people in the streets and the reduction of daily activity and commuting, which caused an unprecedented silencing on a large scale. Along with the silence that ensued, the pandemic and the confinements affected acoustics and our relationship with sounds on different scales. In the cities, this phenomenon had a strong reduction in acoustic intensity due to the absence of vehicles on the streets. Perhaps this was more perceptible in our neighborhoods, with notable changes in their soundscapes, first due to the absence of people in the streets and later due to more outdoor activity derived from the fear of the spread of the virus in indoor spaces. The longer periods of time spent in our homes during the lockdowns also highlighted the importance of sound insulation in buildings and the acoustic conditioning of our schools or homes.
本综述旨在分析疫情对全球声音环境的影响。
与疫情相关的封锁措施导致全球声音水平降低，且在没有交通噪音和人为噪音的情况下，声景感知发生了变化。
为应对新冠疫情，2020年全球许多国家和地区采取了一系列被称为“封锁”或“禁闭”的干预措施。这些限制措施产生了一个明显的后果，即街道上行人减少，日常活动和通勤量降低，从而在很大范围内造成了前所未有的寂静。伴随着随之而来的寂静，疫情和封锁在不同层面上影响了声学以及我们与声音的关系。在城市中，由于街道上没有车辆，这种现象导致声学强度大幅降低。或许在我们的社区中这种现象更为明显，其声景发生了显著变化，首先是因为街道上行人减少，后来是因为人们担心病毒在室内空间传播而增加了户外活动。封锁期间我们在家中度过的较长时间也凸显了建筑物隔音以及学校或家庭声学调节的重要性。
