We propose an effective approach to acoustic indoor localization that works in reverberant environments. The proposed localization system has been implemented to operate in an inaudible frequency range for practical applications. In order to achieve high performance, we propose an effective acoustic source data structure with a synchronization algorithm. To(More)
Musical instruments radiate sound with specific directivity patterns in 3-dimensional space. The room transfer functions between a source and a receiver in concert halls also depend on the direction of sound radiation and arrival. Listeners perceive sound in 3-dimensional space. This paper explains the methods on the auralization of musical instruments in(More)
In this letter, we propose a robust approach to time-delay estimation for acoustic indoor localization. Particularly, we focus on the acoustic indoor localization that works in real environments, which have been seldom addressed in previous studies. In the actual environments, it is difficult to estimate the correct time delays for localization due to(More)
