DESCRIPTION:Noise Pollution and Infant Health\n\nNoise\, or unwanted sound\
 , is ubiquitous in urban environments. I introduce a new approach to measur
 ing noise at scale using seismometers and compile the largest publicly avai
 lable database of ambient noise. Using a research design leveraging idiosyn
 cratic variation in electric passenger rail noise exposure\, I estimate the
  impact of noise pollution on infant health. In utero noise pollution expos
 ure harms health at birth. A 2 decibel increase in average noise levels dur
 ing pregnancy—a small but perceptible increase—lowers an overall index meas
 ure of infant health by 4 percent of a standard deviation\, equivalent to o
 ne-third of the Black-White gap in the index. This effect is driven by nigh
 ttime noise\, suggesting disruptions to maternal sleep as a main mechanism.
  Overnight rail services\, which account for only about 5 percent of overal
 l ridership\, generate an average externality of $18 per trip. In per passe
 nger-mile terms\, overnight rail noise externalities are comparable to rush
  hour traffic congestion externalities from private vehicles. Using seismic
  data and machine learning\, I produce a novel map of noise for the contigu
 ous United States and use this map to assess noise exposure and costs natio
 nally. Eighty percent of urban residents are exposed to potentially harmful
  levels of nighttime noise. I estimate that the annual cost of noise pollut
 ion due to harms to health at birth is $9.8 billion. Urban\, Black\, and Hi
 spanic Americans disproportionately bear these costs.\n\nBiography\n\nSimon
  Greenhill is a PhD candidate in Agricultural and Resource Economics at UC 
 Berkeley. His research focuses on the measurement and regulation of environ
 mental externalities\, including water pollution\, climate change\, and noi
 se pollution. Simon's research has been published in Science\, and he was a
  lead author of the Economics chapter of the Fifth National Climate Assessm
 ent. He holds undergraduate degrees in economics and Arabic from UC Berkele
 y and worked as a pre-doctoral fellow in the Climate Impact Lab prior to gr
 aduate school.
