New CLBO method predicts acoustic fields with higher accuracy and speed

Researchers have developed a new method called the Quadrature-Aware Complex-Linear Boundary Operator (CLBO) to predict acoustic fields from boundary excitations more efficiently. This operator maps complex normal velocity on a vibrating surface to complex pressure at receiver locations, by coupling learned basis functions through an explicit complex surface-quadrature contraction. CLBO demonstrated significantly lower prediction errors and was substantially faster than a Complex DeepONet, showing improved physical consistency and generalization for distributed acoustic excitation.
