Thanks for the PR. The weightings that are now modified are now no longer according to IEC 61672-1:2003. Please keep those as they were and instead have a copy for NOAA in a separate module. |

Considering this is following guidelines or a standard, it may be better to follow the approach in the |

Thanks for the feedback. I have moved all NOAA related logic/tests into separate files |

I think we should make this public so we can remove all duplicate code.

There is a different frequency range defined in the two files. Could you please indicate where you want the public method located and how you imagine it should look like?

Hi there,
Just following back on this old PR: Could I kindly get you to elaborate on your comment so I can amend my code and we can complete this request?
General comments:
This PR adds auditory weighting functions as specified in NOAA guidelines document 'Technical Guidance for Assessing the Effects of Anthropogenic Sound on Marine Mammal Hearing' available at https://www.fisheries.noaa.gov/webdam/download/75962998 (Table ES2 and formulas below)
This enhancement would make the module more useful for underwater acoustics.
This weighting is currently being frequently used in contexts of environmental impact assessments when discussing underwater noise in US but the general trend suggests that NOAA guidelines will be adapted in other countries (e.g. UK).
Implementation comments:
Besides adding additional weightings I also had to increase the frequency range to 200 kHz ->Some weighting curves are applied at much higher frequencies.
