Bibliography & Educational Resources

Noise Navigator Spreadsheet

Welcome to the Noise Navigator spreadsheet of sound levels for more than 1700 occupational, recreational, and military noise sources. The data are compiled from references in the literature and from our own measurements. For each source the reference is listed, and as available additional notes are provided. When the primary reference cites sources for its data, those too are listed. View the Noise Navigator Spreadsheet. We are interested in refining and expanding this resource. If the reader has suggestions for improvement, or documented sound levels that they wish to share, or finds any items requiring explanation or correction, please contact Elliott Berger at [email protected].

The file is free to download, but please provide credit to Dr. Martin if you use the file for training or demonstration purposes.
