The wave field analysis and synthesis of an acoustic filed in rooms using the concept of a direction of arrival algorithm

Document Thumbnail

This paper is a proposal for an extension of the WFS method towards a new direction in adaptive sound reinforcement systems. The positions of sound sources may be found using array signal processing techniques. Analysis of an acoustic field can be performed on a microphone array using the Direction of Arrival algorithm, which can estimate angle of arrival of acoustic waves, like tones or speech signals. This paper presents real time analysis of an acoustic field based on the implementation of DOA algorithms on the DSP board.
