Low frequency sound field reconstruction in a non-rectangular room using a small number of microphones

An accurate knowledge of the sound field distribution inside a room is required to identify and optimally locate corrective measures for room acoustics. However, the spatial recovery of the sound field would result in an impractically high number of microp ...

Joint Human Pose Estimation and Stereo 3D Localization

Alexandre Massoud Alahi, Sven Kreiss, Lorenzo Bertoni, Wenlong Deng

We present an end-to-end trainable Neural Network architecture for stereo imaging that jointly locates and estimates human body poses in 3D. Our method defines a 2D pose for each human in a stereo pair of images and uses a correlation layer with a composit ...

Modeling extended-reaction boundary conditions in time-domain wave-based simulations of room acoustics

Jan Sickmann Hesthaven

This paper presents a general method for modeling extended-reaction surface impedance boundary conditions in time-domain wave-based room acoustic simulations. A sound field separation technique is used to separate the sound field at a boundary into its inc ...
