Planar Near-field Acoustic Holography Point Source Simulation

This text describes a planar near-field acoustic holography point source simulation program. The program utilizes holographic surface data to reconstruct sound pressure information through back-propagation algorithms, enabling more accurate simulation of sound wave propagation and reflection. This simulation likely employs mathematical formulations based on the Helmholtz equation and Fourier transform techniques to calculate the acoustic field. Developed by acoustic engineers or specialists in related fields, such programs may require weeks or even months of refinement to optimize performance. The significance of this program lies in its ability to provide researchers in industrial, scientific, and medical fields with more precise data, allowing them to better understand sound wave behavior and characteristics across various environments. The implementation typically involves spatial domain processing, wavenumber spectrum analysis, and regularization methods to handle inverse problems. Therefore, planar near-field acoustic holography point source simulation can be considered an important technological tool that advances our understanding and development in acoustics and related disciplines.
