Research Abstract

It is difficult to estimate a direction of arrival (DOA) accurately, when a target sound source is surrounded by acoustic interferences such as a variety of noises and reverberation. In this study, integrated modeling of both the target source and background noises is proposed to achieve robust DOA estimation under noisy environments. The model relies on acoustic characteristics of the source and the background noise, and is unified based on confidence of each DOA estimate, which is also proposed in this study. Feasibility of the proposed method has been confirmed under non-stationary noisy environments.
