Teacher-Mediated and Student-Led Interaction with a Physics Simulation: Effects on the Learning Experience

Computer simulations are often used as support material for science education, as they can engage students through inquiry-based learning, promote their active interaction in the experimentation phase, and help them visualize abstract concepts. For instanc ...

Scattering from Time-Modulated Transmission-Line Loads: Theory and Experiments in Acoustics

Romain Christophe Rémy Fleury, Matthieu Francis Malléjac

Scattering wave systems that are periodically modulated in time offer many new degrees of freedom to control waves in both the spatial and frequency domains. Such systems, albeit linear, do not conserve frequency and require the adaptation of the usual the ...

Deep Learning Approaches for Auditory Perception in Robotics

Weipeng He

Auditory perception is an essential part of a robotic system in Human-Robot Interaction (HRI), and creating an artificial auditory perception system that is on par with human has been a long-standing goal for researchers. In fact, this is a challenging res ...

Wave-conversion active liner based on generalized Snell-Descartes law

Hervé Lissek

The Cremer’s impedance theoretical framework has been used for years to optimally design acousticliners for the aeronautic industry, such as honeycomb liners. This passive mean of sound absorption,which consists in rather thin (a few centimeters) honeycomb ...

Active Times for Acoustic Metamaterials

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

Initially proposed to achieve strong noise isolation levels beyond the mass-density law, acoustic metamaterials (AMMs) have now overturned the conventional views in all aspects of sound propagation and manipulation. In fact, within the last two decades, th ...

Parity-Time Acoustic Metamaterials and Unidirectional Invisible Sensors

Romain Christophe Rémy Fleury

We theoretically and experimentally investigate the unique scattering properties of parity-time acoustic systems. We observe acoustic invisibility of airborne sound at audible frequencies in a parity-time symmetric meta-molecule made of perfectly balanced ...

Virtual Reality for Architectural Acoustics

Dirk Schröder

Over the last decades, powerful prediction models have been developed in architectural acoustics, which are used for the calculation of sound propagation in indoor and/or outdoor scenarios. Sound insulation is predicted rather precisely by using direct and ...

Hardware-Software Inexactness in Noise-aware Design of Low-Power Body Sensor Nodes

David Atienza Alonso, Pierre Vandergheynst, Giovanni Ansaloni, Mohamed Mostafa Sabry Aly, Hossein Mamaghanian

Wireless Body Sensor Nodes (WBSNs) are miniaturized and ultra-low-power devices, able to acquire and wirelessly trans- mit biosignals such as electrocardiograms (ECG) for extended periods of times and with little discomfort for subjects [1]. Energy efficie ...

Structured Sparsity Models for Reverberant Speech Separation

Hervé Bourlard, Volkan Cevher, Afsaneh Asaei, Mohammad Golbabaee

We tackle the multi-party speech recovery problem through modeling the acoustic of the reverberant chambers. Our approach exploits structured sparsity models to perform room modeling and speech recovery. We propose a scheme for characterizing the room acou ...

Multiscale modeling of sound propagation through the lung parenchyma

Jan Sickmann Hesthaven, Paul Isaac Denis Louis Marie Cazeaux

In this paper we develop and study numerically a model to describe some aspects of sound propagation in the human lung, considered as a deformable and viscoelastic porous medium (the parenchyma) with millions of alveoli filled with air. Transmission of sou ...
