The National Oceanic and Atmospheric Administration (NOAA) is pleased to
announce the availability of "Draft NOAA Guidance for Assessing the Effects
of Anthropogenic Sound on Marine Mammals: Acoustic Threshold Levels for
Onset of Permanent and Temporary Threshold Shifts" for a 30-day public
comment period.

NOAA has developed draft guidance for assessing the effects of
anthropogenic sound on marine mammal species under NOAA’s jurisdiction. The
guidance provides updated received levels, or acoustic threshold levels,
based on the best available science, above which individual marine mammals
are predicted to experience changes in their hearing sensitivity (either
temporary or permanent) for all underwater anthropogenic sound sources.
This guidance is intended to be used by NOAA analysts and managers and
other relevant user groups and stakeholders, including other federal
agencies, when seeking to determine whether and how their activities are
expected to result in particular types of impacts to marine mammals via
acoustic exposure. Although NOAA has updated the acoustic threshold levels
from those previously used, and these changes may necessitate new
methodologies for calculating impacts, the application of the thresholds
under applicable statutes (Marine Mammal Protection Act, Endangered Species
Act, and National Marine Sanctuaries Act) remains consistent with past NOAA

In conjunction with this public comment period, we will be hosting a public
meeting on January 14, 2014 in Silver Spring, Maryland. For those unable to
attend in person, there will be webinar access. Please consult the
