Deep PINNs for RIR Interpolation

This paper addresses the problem of estimating Room Impulse Responses (RIRs) from sparse measurements, a crucial task in acoustics. It leverages Physics-Informed Neural Networks (PINNs), incorporating physical laws to improve accuracy. The key contribution is the exploration of deeper PINN architectures with residual connections and the comparison of activation functions, demonstrating improved performance, especially for reflection components. This work provides practical insights for designing more effective PINNs for acoustic inverse problems.
