FIELD Acoustic Simulation Toolkit by Technical University of Denmark

The FIELD Acoustic Simulation Toolkit developed by the Technical University of Denmark is a professional acoustic simulation tool written in MATLAB. This toolkit is primarily used for acoustic field analysis and simulation, widely applied in acoustic research, architectural acoustics design, and audio engineering fields.

The core functionality of the FIELD toolkit involves simulating sound wave propagation in complex environments using numerical methods, including acoustic pressure distribution, reflection, diffraction, and other acoustic phenomena. Its MATLAB implementation enables researchers to flexibly call various algorithms and conduct parametric analysis through scripted workflows, making it particularly suitable for rapid prototyping validation in academic research or engineering development. The code structure typically includes modular functions for wave equation solvers, boundary condition handlers, and visualization routines.

A key feature of this toolkit is its balance between computational accuracy and flexibility. Users can select different numerical methods (such as Boundary Element Method, Finite Element Method) according to their needs, while leveraging MATLAB's matrix operation advantages to optimize computational efficiency. The implementation often utilizes MATLAB's built-in PDE toolbox and custom matrix solvers for handling large-scale acoustic problems. Additionally, FIELD supports integration with experimental data, facilitating verification and calibration of simulation results through data comparison functions.

For acoustic engineers or researchers, the FIELD toolkit provides an efficient research tool that significantly reduces the cost and time associated with traditional experimental testing. The MATLAB environment also lowers the learning curve, allowing non-professional programmers to quickly get started by modifying existing example scripts and parameters through the graphical interface or command-line operations.
