dBSea - Software
Underwater Noise Prediction

dBSea  as a powerful tool for the prediction of underwater noise in a variety of environments.

dBSea user friendly interface allows rapid modelling of problems including data import & export, input of noise sources, definition of propagation properties and exporting of results.

The model is represented in 3D and may be rotated and zoomed to allow easy navigation of the problem environment and examination of prediction results.  Where previous analysis has been limited to individual calculation slices or transects, dBSea allows the entire problem environment to be modeled and analyzed in 3D.

The 3D model is built by importing bathymetry data and placing noise sources in the environment. Each source can consist of equipment chosen from either the standard or user defined databases.  Noise mitigation methods may also be included.  The user has control over the seabed and water properties including speed of sound profile (how the speed of sound changes with water depth), temperature, salinity and current.

Noise levels are calculated throughout the entire project area and displayed in 3D.  To examine results in more detail, levels may be plotted in cross sections or a detailed spectrum may be extracted at any point in the 3D calculation area.

Levels are calculated in octave or third octave bands.  Three different solvers are available and the user may choose different solvers for the low and high frequency ranges.  Levels are compared to hearing thresholds of a number of common marine species to give overall dBht levels.

Special Features

dBSea offers elegant ways to export calculation results.  The user can generate a summary of the calculations for every point in the 3D calculation area.  Results are produced in a format that is ready to be transferred to other software such as MS Excel or Word.

Graphical export is available to a range of formats (JPG, PNG, GIF, PDF).  With the 3D graphics capabilities of dBSea, it is simple to create elegant report data showing sound levels and exclusion zones.
