Résumé

Anthropogenic underwater noise is an increasing environmental concern. Accurate predictions of sound levels from anthropogenic sources are required to estimate the impact on marine life exposed to it. JASCO Applied Sciences has been developing software modeling tools for underwater noise exposure estimation for more than 30 years. Elements of the modelling process include estimation of source level, spectrum, and radiation pattern; environmental characteristics of the underwater sound medium and the geoacoustics of the seabed; calculating the acoustic propagation loss; estimating the received levels, both in terms of rms SPL and Sound Exposure Level (SEL); evaluating species-specific impact weighting; and compiling results into comprehensible summaries. These tools have been developed for accuracy in prediction and efficiency in computation, and have been used in work for a wide range of international clients, both commercial and governmental. This paper presents an overview of the anthropogenic underwater noise and exposure modelling work being done by JASCO.
