The Description of Sound Sources by a Set of Equivalent Sources Using Impulse Response Functions and the Least Mean Square (LMS) Algorithm

Paper i proceeding, 2022

When modelling virtual acoustic environments for research applications it is essential to provide a proper source description. Such a description has to include both the signal contents but also the directivity of the source. In the ideal case the description allows for a time varying directivity due to e.g. movement of a speakers head. In addition the implementation of such a source description should be compatible with the approach used for simulating the environment. The idea behind the presented paper is to formulate a complex original source (OS) by a number of equivalent sources (ES) such as simple monopoles. To allow for time varying properties a time domain formulation is needed.
