Global Sound Field Reconstruction in the Room Environment Based on Inverse Wave-Based Simulation

Shock and Vibration, 2022
An inverse wave modeling-based method is proposed for globally reconstructing the sound field in room environments. The method builds the wave model of the sound field as prior knowledge to support the reconstruction under strong reverberation.

Differentiable physics for sound field reconstruction

The Journal of the Acoustical Society of America
Sound field reconstruction involves estimating sound fields from a limited number of spatially distributed observations. This work introduces a differentiable physics approach for sound field reconstruction, where the initial conditions of the wave equation are approximated with a neural network and the differential operator is computed with a ...

Modified Wideband Acoustical Holography for Improving the Identification of Acoustic Sources at Low Frequencies

IEEE Access, 2023
Source identification and sound field reconstruction using near-field acoustical holography (NAH) is particularly challenging when the measurement data are relatively fewer than the sources to reconstruct.
