APPS – Acoustic Performance Prediction System

APPS calculate the sound propagation and the characteristics of different acoustic systems in a specific underwater environment. The system is used to obtain realistic sound-propagation predictions for commercial sonars, scientific studies, R&D projects and educational tasks.


Internationally Validated.

Internationally validated propagation models and global databases allow the acoustic device performance evaluation in any sea around the world.


Principal Features.

  • Validated propagation models for low and high frequencies.
  • Reverberation calculations for active sonar.
  • Ambient Noise based on sea state and ship traffic.
  • Configuration of environment and acoustic sensor characteristics.
  • Global Databases including Bathymetry and  Global Sound Velocity Profiles.
  • Empty user database for saving own SVPs.
  • 3D calculations providing 360º prediction for every depth.
