Noise, air pollutants and traffic: Continuous measurement and correlation at a high-traffic location in New York City

► We collected and characterized hourly noise, air pollution and traffic. ► Our analysis is the first to disaggregate noise by frequency band. ► Noise was strongly correlated with car and truck traffic and, in some cases, air pollutants. ► Co-exposures between should be considered in some epidemiologic time series studies. Correlations are mediated by the time of day, noise frequency and wind.
