dBSea Underwater Noise Simulation Software

Dual PE and ray-tracing solvers — the go-to tool for offshore wind and harbor EIA.

Overview

Software developed specifically for underwater noise prediction, using multiple solvers for single or multi-source problems across a broad frequency range. 3D workspace for visualizing bathymetry, sources, and results.

Key Features

• Dual solvers: dBSeaPE (parabolic equation) and dBSeaRay (ray tracing)
• Outputs SPL, SEL, SPL peak, peak-to-peak; includes directional airgun seismic source modeling
• 1/1 or 1/3 octave bands from 12.5 Hz to 160 kHz; includes latest impact thresholds and frequency weightings
• Marine mammal species-specific behavioral impact assessment; GIS (ArcGIS/QGIS) integration
• Free dBSea Basic also available (logarithmic spreading loss + full visualization)
