AI Insight
This article presents a spectral element method (SEM) for solving depth-dependent kernel functions within the wavenumber integration framework used to model underwater acoustic propagation. The approach leverages high-order polynomial basis functions to achieve greater numerical accuracy and convergence compared to traditional finite difference or finite element methods when computing acoustic pressure fields in stratified ocean environments. The spectral element formulation offers improved handling of complex layered media, including fluid-solid interfaces, which are commonly encountered in real ocean-bottom configurations.
Why it matters
Accurate modeling of underwater sound propagation is critical for applications such as submarine detection, marine mammal monitoring, seismic surveying, and underwater communications. A more efficient and precise numerical solver can enhance the reliability of sonar systems and environmental acoustic assessments.
