acdecom - acoustic mode decomposition in flow ducts¶
Acdecom is a Python module that makes the post-processing of acoustic data in flow ducts easy. It is developed and maintained by the Marcus Wallenberg Laboratory for Sound and Vibration Research.
The package features:
An easy-to-set-up three-step decomposition scheme for experiments and simulations
Predefined wavenumbers, acoustic mode shapes, and attenuation models for the most common geometries
Preparation of decomposition matrices based on auto-detected cut-on modes
High customizability
Installation¶
The module can be easily installed using PiPy:
>> pip install acdecom
The source code is available at GitHub.
