Acoustic Space Learning for Sound-Source Separation and Localization on Binaural Manifolds

Antoine Deleforge, Florence Forbes, Radu Horaud
2015 International Journal of Neural Systems  
We perform an in-depth study of the latent low-dimensional structure of the high-dimensional interaural spectral data, based on a corpus recorded with a human-like audiomotor robot head.  ...  We propose a probabilistic piecewise affine mapping model (PPAM) specifically designed to deal with high-dimensional data exhibiting an intrinsic piecewise linear structure.  ...  The head is mounted onto a robotic system with two rotational degrees of freedom: a pan motion and a tilt motion (see Fig. 1 ).  ...

RadarSLAM: Biomimetic SLAM using ultra-wideband pulse-echo radar

Girmi Schouten, Jan Steckel
2017 2017 International Conference on Indoor Positioning and Indoor Navigation (IPIN)  
This paper presents a novel method for using an ultra-wideband (UWB), super high frequency (SHF) pulse-echo radar sensor as a biomimetic sensing mechanism to successfully solve the Simultaneous Localization  ...  This Nyquist-conform sampling permits the conversion of the signal waveforms into spectrograms which contain spatiospectral cues caused by the interactions of the echoes with features of the environment  ...  This is accomplished by gathering information from dedicated sensors by which the robot probes its surroundings and supplying it to a probabilistic algorithm.  ...

Acoustics of ancient Greek and Roman theaters in use today

Anders Christian Gade, Konstantinos Angelakis
2006 Journal of the Acoustical Society of America  
In order to achieve an estimate of both azimuth and elevation simultaneously, a new DOA estimation algorithm based on interaural phase and level differences is proposed as a part of frequency domain binaural  ...  The method uses sound diffraction to estimate DOAs and segregate sound sources. The binaural model can estimate one-dimensional DOA, namely, azimuth.  ...  These arrival time differences are used in conjunction with a simple ray-based acoustic model to estimate the source location in three dimensions.  ...
