Riepilogo
The National Marine Fisheries Service (NMFS) announces the availability of our final 2024 Update to: Technical Guidance for Assessing the Effects of Anthropogenic Sound on Marine Mammal Hearing (Version 3.0): Underwater and In-Air Criteria for Onset of Auditory Injury and Temporary Threshold Shifts (2024 Updated Technical Guidance). The 2024 Updated Technical Guidance provides updated information, or acoustic criteria, to predict when individual marine mammals, both in-air and underwater, will experience changes in their hearing sensitivity (auditory injury or temporary threshold shift) from exposure to anthropogenic sound sources. The 2024 Updated Technical Guidance replaces NMFS's current 2018 Revisions to: Technical Guidance for Assessing the Effects of Anthropogenic Sound on Marine Mammal Hearing (Version 2.0): Underwater Thresholds for Onset of Permanent and Temporary Threshold Shifts (2018 Revised Technical Guidance).
