Multi-layered graphical user interface for constructing block diagram models of flow duct networks; multiple sources and outlets can be included; system block diagram can be linked to a drawing or a sketch.

Open end radiation into fractional free-fields and diffuse fields.

Signal analyzer for driving sources, audio play, and post-processing of results or measured signals.

User-friendly input datasheets with formula writing, syntax and compatibility checking capabilities.

Parametric and doe calculations with selected parameters and arbitrary constraints; direct, stochastic, and inverse optimization capabilities.

Results of calculations are plotted on-line and can be stored in a file.

Element database contains passive two-ports and multi-ports in 1-D and 3-D; one-port and two-port sources; multi-ports have variable number of ports; measured and FEM based two-port elements can be imported; users can create (without any programming) new elements in 1-D and 3-D and new one-port sources.

Processing of microphone signals acquired in measurement of one-port source characteristics and two-port transfer matrices by state-of-the-art methods.

Frequency analysis and order analysis capabilities under ambient gradients and fluid options (gas, liquid, burnt product, refrigerant, etc.); mean pressure losses in elements are calculated along with acoustic calculations.

Extensive on-line help, tutorials and compact installation.
