NIOSH Health Hazard Evaluation Program Noise Measurement Database
We have released a database to provide researchers and other interested stakeholders with noise measurement results collected during HHE surveys from 1996–2012. The noise database contains workplace noise measurement results from 73 HHE reports, including over 761 personal noise exposure measurements and 536 area noise measurements. For reports posted online, the database provides a direct link to the HHE report for each of the noise measurement results. This database is an ongoing project and will be updated at least yearly to add the most recent HHE noise measurement data. To view the database go to
