3-D sound reproduction system for immersive environments based on the boundary surface control principle
TL;DR: A 3-D sound reproduction system containing a 62-channel loudspeaker array and 70-channel microphone array based on the boundary surface control principle (BoSC) can achieve high presence for 3- D sound reproduction and provide the listener with deep immersion.

Distinguishing between the interior pressures induced from two independent sources within a room using the probabilistic approach
TL;DR: In this article, a probabilistic approach is introduced and used to distinguish between the interior pressures that are induced from two independent sound sources within a rectangular room, one source is a vibrating wall of the room and the other is an interior point source.
Directivity of human and artificial speech
TL;DR: In this article, a study on how directivity characteristics of articial mouths correspond to the directivity of a real speaker was conducted, where the measurement positions corresponded to the same positions were the microphones of phones and their accessories, so called headsets, would lay.

Sparse sound field decomposition with multichannel extension of complex NMF
TL;DR: Since the magnitude spectrum of the possible source signals can be trained in advance, accuracy of the sparse decomposition can be improved even when the source signals are highly correlated and the sources are in a highly noisy environment.
Proceedings ArticleDOI
Source-location-informed sound field recording and reproduction with spherical arrays
TL;DR: Numerical simulations show that the reproduction accuracy at frequencies above the spatial Nyquist frequency was maintained using the proposed method even when there was a mismatch between actual and prior locations of the sound sources to be reproduced.
