Population health implications of exposure to pervasive military aircraft noise pollution

DOI

This repository contains the reproducible methods and workflow routines used in the research article:

Jacuzzi G., Kuehne L.M., Harvey A., Hurley C., Wilbur R., Seto E., Olden J.D. Population health implications of exposure to pervasive military aircraft noise pollution. Journal of Exposure Science and Environmental Epidemiology (2024). https://doi.org/10.1038/s41370-024-00670-1

While this code was developed for the objectives of this specific study, it can be freely repurposed for other noise monitoring and health assessment initiatives. Please cite the original publication in your references and direct any correspondance to [email protected].

Data availability

Refer to the Data Availability statement in the paper for links to requisite data, including:

  • Navy acoustic data from the NAVFAC database, exported from Larson Davis binary in xlsx format in the same directories as the original binary files.
  • NPS acoustic data from the National Park Service Night Skies and Sounds Division, in txt format.
  • JGL acoustic data from JGL Acoustics, Inc. in csv format.

Software and package dependencies are listed in methods.Rmd.

Contents

The full data processing and analysis pipeline described in the "Materials and Methods" section of the paper can be found at methods.Rmd. global.R contains global variables, functions, and settings used throughout the repository. See sections below corresponding to repository directories.

analysis

Noise regime

  • Single event acoustic metrics
  • Cumulative acoustic metrics
  • Temporal distribution of noise

Population noise exposure

  • Dasymetric population density estimation
  • Health risks associated with published thresholds

Population health impacts

  • Exposure-response relationship estimates
  • Childhood learning estimates
  • Hearing impairment doses
