Noise pollution and violent crime☆

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.
