dBSea has been developed by Marshall Day Acoustics and Irwin Carr Consulting as a powerful tool for the prediction of underwater noise in a variety of environments.
dBSea is ideal for the investigation of underwater acoustic problems involving single or multiple sources using solvers covering a wide frequency range.
The software incorporates a user friendly interface and clearly defined workflow that allow models to be quickly developed and modified. The 3D workspace allows clear visualisation of bathymetry data, noise sources and prediction results. See example here.
The solvers incorporated into dBSea to predict the underwater sound field comprise the most popular calculation methods used in the underwater acoustics industry. The different solver algorithms each find application with different types of problems, adding up to an overall package that covers many underwater acoustics scenarios. dBSea incorporates source directivity for airgun seismic survey predictions and plots output levels as SPL, SEL, SPL peak or SPL peak to peak.
These solvers make dBSea a robust and reliable tool for consultants and other technical professionals.
