Mammal Hearing: Underwater Acoustic Thresholds for Onset of Permanent and
Temporary Threshold Shifts (2018 Revised Technical Guidance). This User
Manual provides detailed instruction sand examples on how to use NMFS’ optional User Spreadsheet tool, which incorporates the 2018 Revised Technical
Guidance’s acoustic threshold levels to determine whether and how sound-producing activities are expected to result in hearing impacts to marine mammals.
NMFS must receive any comments by November 8, 2018.
