Noise pollution and violent crime☆
利用飞机着陆方式引起的日常噪声变化，发现背景噪声增加4.1分贝导致暴力犯罪率上升6.6%，且主要为针对男性的身体攻击，揭示了噪声污染超出健康影响的社会成本。
This paper reveals how exposure to noise pollution increases violent crime. To identify the causal effect of noise pollution, I use daily variation in aircraft landing approaches to instrument noise levels. Increasing background noise by 4.1 decibels causes a 6.6% increase in the violent crime rate. The additional crimes mostly consist of physical assaults on men. The results imply a substantial societal burden from noise pollution beyond health impacts.
