Draft Guidance for Assessing the Effects of Anthropogenic Sound on Marine Mammals-Acoustic Threshold Levels for Onset of Permanent and Temporary Threshold Shifts

Zusammenfassung

The National Marine Fisheries Service (NMFS) on behalf of NMFS and the National Ocean Service (referred collectively here as the National Oceanic and Atmospheric Administration (NOAA)), announces the availability of draft guidance for assessing the effects of anthropogenic sound on marine mammal species under NOAA's jurisdiction. The guidance provides updated received levels, or thresholds, above which individual marine mammals are predicted to experience changes in their hearing sensitivity (either temporary or permanent) for all underwater anthropogenic sound sources. NOAA solicits public comment on the draft guidance.
