The Full-Frequency Acoustics Toolbox (FullFAT) is an easy to use piece of software which allows for acoustic simulations of non-rectangular topologies. The modeling technique utilized is an image source method. Boundary conditions are treated as perfectly rigid with frequency-independent absorption. Any number of sources can be placed within the space (limited by the number of pressure grid points). By default, sources are omnidirectional point sources. Dipole or cardioid polar patterns are possible as well.

Any number of listening points can be placed within the acoustical space (limited by the number of pressure grid points), placed automatically in a grid or manually by the user. Each listening point records the pressure response during the simulation which can be used later for data analysis.

Further options include time/frequency domain analysis as well as bespoke tone burst analysis and auralization. The full features of this toolbox are described within this user’s guide.

Under no circumstances may this toolbox be used in commercial/for-profit applications. However, you are most welcome to use the program to support research, although formal acknowledgement is expected.

Feel free to contact me regarding any found bugs (there are most likely some lurking within the code!) or to request additional features.

Enjoy using the toolbox. Hopefully it will be of use to your research/interests and contribute to your knowledge and understanding of low-frequency acoustics!


FullFat is downloaded as a .zip file containing the installation file and the user’s guide. The installation file should take you through the process and automatically install MATLAB runtime, if you don’t already have it installed. If you have any issues, please contact me.
