Modelling in acoustics

Course Description

Consideration acoustic elements, systems and instruments physical modells and their implementation in digital domain. Representation of acoustic elements and systems by using ordinary differential equations, partial differential equations and finite difference methods. Represent acoustic elements and systems by using state-space diagram. Representation of vibration modes and propagation through different medium structures by using digital filter and digital waveguide model. Equivalent electrical circuits of acoustic elements and effects in discrete domain. Modelling sound propagation in open space in complex geometry by including all propagation effects.
