Actran: Acoustic Simulation-Sound

Improves the acoustic performance of your designs with this complete Simulation Solution used by leading manufacturers around the world

Actran is the premier acoustics software to solve acoustics, vibro-acoustics, and aero-acoustics problems.

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.

Sample Applications:

    • Sound radiation by vibrating structures: powertrain, engine components (oilpan, intake manifold and air filter, valve cover, etc.), compressors, electrical motors, loudspeakers and more.
    • Intake and exhaust noise, including complex mufflers and silencers.
    • Air conditioning units and distribution systems (calculation of transfer matrices coefficients).
    • Sound absorption inside passenger compartment of cars, trains and aircrafts.
    • Sound propagation in complex media with mean flow or temperature gradient.
    • Audio devices such as telephones, hearing aids or musical instruments.
