Swift and intuitive acoustic prediction tools to deliver high-performing products
Actran enables you to push the boundaries of acoustic design, by reducing product development time and gathering increased insights into how to improve product performance. Its advanced simulation tools make predicting acoustic issues a seamless task.
Benefits And Features
A complete acoustic simulation solution for tackling any acoustic or noise problem
Actran Acoustics
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, Actran for Trimmed Body, and Actran TM.
Actran VibroAcoustics
With the ability to simulate realistic modeling boundary conditions by combining dynamic, kinematic and acoustic constraints, as well as physical excitations like diffuse sound field and turbulent boundary layer, Actran AeroAcoustics can obtain accurate representation of the acoustic performance of your designs
Actran AeroAcoustics
Using Actran AeroAcoustics, the noise generated by any turbulent flow can be thoroughly predicted. Users can benefit from all features of the Actran software suite to study the interaction between the aeroacoustic noise sources and a vibrating structure, absorbent materials, or acoustic traps such as resonators.

Frequently Asked Questions
How to perform a map difference in Actran VI
Following article explains how to perform the difference between two maps in Actran VI on a demo case. The demo case is the turbomachine inlet from Actran TM training material workshop. Difference of acoustic pressure radiated by the nacelle inlet (in no flow) between Hardwall and Softwall configurations is performed and visualized. NFF database with the difference of acoustic pressure is finally exported.
How to define reference spectrum for Diffuse Sound Field excitation in Actran
Following article explains how to:
- Set-up the reference spectrum of a DSF with a value per discrete frequency or a value per (third-)octave band
- Check that reference spectrum specified by the user has been accurately applied
How to include Nastran model into Actran model
Following article aims at:
- Providing guidelines for
+ either the conversion of Nastran model into an Actran model
+ or the use of Nastran modal basis into Actran
- Validating on a simple model:
+ Conversion of Nastran structure model into Actran structure model
+ Use of Nastran structure modal basis in Actran
How to compute incident power for structure TL under distributed pressure excitation
Incident power is commonly assessed to compute structure TL under Diffuse Sound Field excitation. Following article explains how to compute an equivalent incident power when structure is loaded by a deterministic excitation such a distributed pressure.
How to define periodic boundary conditions
Periodic boundary conditions enable to model an angular sector instead of a full 3D model. This leads to lower computation time and lower consumed RAM. Following article explains how to define periodic boundary condition in Actran. It also presents a demo case validating the feature by comparing results on an angular sector and results on a full 3D model.
