气候变化可能到2050年扩大机场噪音区,特别是在欧洲,因为飞机攀升的空气变暖减慢。 Climate change may expand airport noise zones by 2050, especially in Europe, due to warmer air slowing aircraft climbs.

一项新的研究预测,气候变化到2050年将大大增加机场噪音,特别是在欧洲,因为温暖的空气会减少飞机升降,减缓攀升速度,延长噪音暴露时间。 A new study predicts climate change will significantly increase airport noise by 2050, especially in Europe, as warmer air reduces aircraft lift and slows climb rates, prolonging noise exposure. 研究人员发现,起飞攀爬角度平均可下降3%,热日可下降7.5%,使受飞机噪音影响的地区扩大,特别是在50Decibel门槛。 Researchers found takeoff climb angles could drop by up to 3% on average and as much as 7.5% on hot days, expanding the area affected by aircraft noise—particularly at the 50-decibel threshold. 在伦敦中部,目前约有60 000人生活在这个噪音区,由于气候和人口变化,预计还会增加约2 500人。 In central London, about 60,000 people currently live within this noise zone, with roughly 2,500 more expected to be added due to climate and population shifts. 低频噪音走得更远,干扰性更强,预计将增加最多,增加压力和睡眠问题的风险。 Low-frequency noise, which travels farther and is more disruptive, is projected to rise the most, increasing risks of stress and sleep issues. 科学家警告说,即使改进了发动机技术,气温上升将使噪音管理更加困难,除非减少温室气体排放量。 Scientists warn that even with improved engine technology, rising temperatures will make noise management harder unless greenhouse gas emissions are reduced.
