A recent study has found that the Argentine capital of Buenos Aires is the noisiest city in Latin America. It is also the fourth loudest in the world following New York, Tokyo and Nagasaki, according to previous findings by the World Health Organization (WHO)。

　　最近的一项研究显示，阿根廷首都布宜诺斯艾利斯是拉丁美洲最嘈杂的城市。而据此前世界卫生组织调查显示，布宜诺斯艾利斯也是是继纽约、东京和长崎之后的世界第四嘈杂城市。

　According to the study, reason for the title is that the city works during the day and comes alive at night, sometimes to the rhythmic beat of the tango。

　　研究显示，布宜诺斯艾利斯获得此项头衔的原因在于，这个城市白日忙于劳作，夜晚也不安宁，(人们有时可以听到)探戈舞曲的节拍声。

　　Roughly one-third of 40 million inhabitants live in or near the city. They live in high-rise blocks of flats on long, straight streets which channel the sound. Meanwhile, a thriving economy has resulted in more cars on the city's already crowded roads, and an increase in construction work. The city is also hot and humid, so windows are left open or air-conditioners whirr away day and night。

　　阿根廷4000万总人口中约1/3居住在布宜诺斯艾利斯或附近。他们挤在高层住宅里，又长又直的街道能起到传声效果。另外，经济发展使得更多汽车出现在本就拥挤的道路上，施工工程也越来越多。而当地天气湿热，窗户常常大开，空调日夜运转。

　　The World Health Organization suggests that healthy noise levels should not surpass 55 decibels during the day and 45 at night, but measurements taken in Buenos Aires regularly hit 70 or even 80 decibels, which is bad for the ears and could cause stress。

　　世界卫生组织建议，健康的噪音标准应该是白天不超过55分贝，晚上不超过45分贝，但布宜诺斯艾利斯经常达到70甚至80分贝。这样的噪音不利耳朵，也会引发压力。

　　With no immediate improvement in sight, the only solutions are to leave the city, wear ear muffs or talk a little louder。

　　英国广播公司报道称，目前该城市的噪音问题还没有明显改善，唯一的解决办法就是离开此地、戴上耳套或者讲话大声点。
