Dataset of 3D Reconstruction for Optically-measured Sound Field

Description This sound field dataset contains 3D sound fields of real and imaginary parts of complex amplitude and 2D line-integrated sound fields. The dataset was initially prepared for the paper "Data-driven Volumetric Reconstruction for Optically Measured Sound Field using Physics-constrained 3D Gaussian Splatting". Please check our paper for more details.

Soc. Am. 1 September 2025; 158 (3): 2163–2175. https://doi.org/10.1121/10.0039344 Data Structure The dataset is organized into two main directories: simulation/: Contains simulation-based sound field data experiment/: Contains experimental data 1. Simulation Data (/simulation/) There are two types of sub-directories under simulation/: soundsource#/ — Simulation results with varying numbers of sound sources (# = number of sources) sim_burst10kHz/ — Specific burst waveform simulation (not detailed here) 2. Experimental Data (/experiment/) This directory contains measured projection data from real-world experiments.Unlike simulation data, ground-truth volumes are not available.Instead, a pseudo-ground-truth volume is provided using filtered back projection reconstruction for reference.
