Acoustical Modeling & Simulation

Our areas of competency in Acoustical Modeling & Simulation include

  • Physical Models for Propagation, Reverberation, and Scattering in the Ocean and in Air
  • Fidelity Assessment for Simulation-Based Training
  • Scale-Model Validation Studies

By understanding the needs of the end user, whether a tactical-decision aid or real-time training system, ARiA is able to develop models and evaluate their fidelity with scientifically rigorous and tactically meaningfully metrics. Fidelity in modeling is a means to end, not a goal in itself.

Advances in modeling & simulation now enable simulation-based training to augment live training in many applications. But the viability of simulation-based training rests on understanding the relationship between training goals and fidelity and ensuring that the computational load and instructor load resulting from scenario design are optimized jointly with training goals. ARiA is developing new algorithms that automate the process of scenario design that work interactively with instructors to ensure that fidelity is sufficient to meet training goals while balancing restrictions due to computational load.
