Marine Bioacoustical Standardization

Observations and experiments related to sound production and sensing by marine organisms use a variety of methods and measures, making it difficult to compare results from different locations. This working group has been developed to make bioacoustic measurements more comparable.

The primary tasks of the IQOE >Marine Bioacoustical Standardization Working Group are to:

  1. identify any existing standards for marine bioacoustics* and ecoacoustics**;
  2. promote best practices from the standards identified in Task 1;
  3. identify knowledge gaps and areas that need standardization from Task 1; and
  4. fill the knowledge gaps identified in Task 3 by recommending development of new standards and improvements to existing ones.

*For the purposes of this IQOE WG, "marine bioacoustics" is defined as characterization of sound production by marine life (e.g., individual sources through to soundscapes), the production or reception of sound by marine life, and the interaction of sound with marine life. In the present context it includes

  • characterization of sound production by marine life (e.g., source level);
  • sound reception by marine life (e.g., audiograms);
  • acoustic metrics for understanding impacts on marine life, including auditory weighting functions;
  • scattering of sound by marine life (e.g., scattering cross section); and
  • bioacoustical terminology for all the above topics.

**"Ecoacoustics" is the study of biological sounds in an environment to understand the broader ecology and community.
