Electroacoustic absorbers: Bridging the gap between shunt loudspeakers and active sound absorption

Romain Christophe Rémy Fleury, Hervé Lissek, Romain Boulandet

The acoustic impedance at the diaphragm of an electroacoustic transducer can be varied using a range of basic electrical control strategies, amongst which are electrical shunt circuits. These passive shunt techniques are compared to active acoustic feedbac ...

Reproducing Sound Fields Using MIMO Acoustic Channel Inversion

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Sound fields are essentially band-limited phenomena, both temporally and spatially. This implies that a spatially sampled sound field respecting the Nyquist criterion is effectively equivalent to its continuous original. We describe Sound Field Reconstruct ...

Electroacoustic absorbers II: implementation of a digital synthetic admittance for controlling the dynamics of electroacoustic absorbers

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet

This paper discusses the implementation of a synthetic electrical admittance for controlling the dynamics of electroacoustic absorbers. Indeed, different basic control techniques are capable of varying the acoustic impedance of an electroacoustic transduce ...

Audio-visual synchronization recovery in multimedia content

Touradj Ebrahimi, Jong Seok Lee

This paper proposes a method recovering audio-visual synchronization of multimedia content. It exploits the correlation between the acoustic and the visual signals in order to estimate the audio-visual drift existing in the content. By shifting the audio s ...

Design of a 2.4 Ghz BAW-Based CMOS Transmitter

Matteo Contaldo

In recent years, bulk acoustic wave resonators (BAW) in combination with RF circuits have shown a big potential in achieving the low-power consumption and miniaturization level required to address wireless sensor nodes (WSN) applications. A lot of work has ...

Audio-based nonlinear video diffusion

Pierre Vandergheynst, Anna Llagostera Casanovas

We propose a novel non-linear video diffusion approach which is able to focus on parts of a video sequence that are relevant for applications in audio-visual analysis. The diffusion process is controlled by a diffusion coefﬁcient based on an estimate of th ...
