SATURN Deliverable D2.2: Guidelines for Sound Particle Motion Mapping
July 2024 — Canada
Client: European Commission
Models for mapping sound pressure metrics over the environment in which animals are exposed to underwater radiated noise from ships have been developed in previous projects and applied in European ambient sound monitoring projects such as BIAS, JOMOPANS and JONAS. However, these maps represent metrics based on sound pressure within set frequency ranges. The capability to produce maps of metrics based on sound particle motion, to which many fish and invertebrate species are sensitive, still needed to be developed. This deliverable from Task 2.3 ‘Sound Particle Motion Modelling and Mapping’ of the EU-funded research project SATURN (Developing solutions to underwater radiated noise) describes the results of the development of the capability to produce sound particle motion maps. It describes the relevant sound particle motion metrics and how these relate, describes models that can be used for producing sound particle motion maps, describes how these models can be verified and validated and provides some examples of calculated particle motion sound maps. The final chapter of this report summarizes guidelines for sound particle motion mapping.
