Free Field Technologies (FFT), a leading global company focused on acoustic simulation and engineering services, has presented the 15.0 version of Astran is the premier acoustics software to solve acoustics, vibro-acoustics, and aero-acoustics problems.

Used by automotive manufacturers and suppliers, aerospace and defense companies, and consumer product manufacturers, Actran helps engineers better understand and improve the acoustics performance of their designs.

Actran provides a rich library of material models, a complete element library that includes infinite elements, high performance solvers to solve large size problems and a user-friendly GUI that is highly customizable to your needs. Actran, with its modular nature, can be deployed based on your applications and requirements.

Actran Acoustics is the foundation module of the Actran family. It is both a standalone tool and is a pre-requisite for advanced modules like Actran VibroAcoustics, Actran AeroAcoustics and Actran TM. Some of the robust capabilities of this module include:

- Simulate standard and convected acoustics
- Extract acoustic modes
- Analyze sound field in cavities, with either modal or physical approaches
- Model absorbing walls using impedance conditions of porous material models
- Analyze sound radiation
- Analyze sound propagation in ducts, intake and exhaust lines or distribution systems in buildings, aircrafts, and automobiles
- Recover vibration results from most FEA structural solvers for radiation analysis
