How to Help

We are interested in full-shift Time-Weighted Average (TWA) noise measurements of workers in US and Canadian workplaces. We would like the following information for each measurement:

  • Job title of measured worker
  • Industry of measured worker
  • TWA of each measurement
  • Standard used (eg. OSHA, NIOSH)
  • Peak Level (if available)
  • Date (month/year)
  • Duration (hours)

Reading Dosimeter

We DO NOT want any information that identifies individual workers, and we will NOT identify companies that contribute to the JEM unless they specifically request in writing to be identified. If you have anonymous noise measurement data that you are willing to share, please contact us at
