Optimization of electroacoustic resonators for semi-active room equalization in the low-frequency range

Hervé Lissek, Etienne Thierry Jean-Luc Rivet

At low frequencies, standing waves within the room cause large frequency-response variations in the listening environment, such as audio rooms or recording studios. This unwanted phenomenon has a significant impact on the sound quality of an audio system. ...

Development of electroacoustic absorbers as soundproofing solutions for industrial ventilation systems

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Victor Desarnaulds

In many industrial environments, room and cavity modes may severely strengthen the annoyance of low frequency noises, such as in ventilation equipments. Moreover, there is an obvious technological gap in the state-of-the-art relative to low-frequency sound ...

Ultra high-speed electronics for power system dynamic emulation

Laurent Fabre

Modern society is dependent on reliable electricity for security, health, communication, transportation, finance, computers and nearly all aspects of the contemporary life. Providing reliable electricity is a very complex challenge. It involves real-time m ...

Multi-channel low-frequency room equalization using perceptually motivated constrained optimization

Martin Vetterli, Mihailo Kolundzija, Christof Faller

We consider the problem of multiple-loudspeaker low-frequency room equalization for a wide listening area, where the equalized loudspeaker is helped using the remaining ones. Using a spatial discretization of the listening area, we formulate the problem as ...

An ultra high-speed, mixed-signal emulator for solving power system dynamic equations

Maher Kayal, Sidi-Rachid Cherkaoui, Laurent Fabre, Ira Nagel, Fabrizio Lo Conte, Guillaume Olivier Lanz

This paper focuses on a new pipelined processing unit architecture dedicated to mixed-signal power system emulation. Prior research in this field has proven that analog emulation overcomes the speed limits of numerical simulators with reliable accuracy. Th ...

Beamforming with a Maximum Negentropy Criterion

Weifeng Li, Philip Neil Garner

In this paper, we address a beamforming application based on the capture of far-field speech data from a single speaker in a real meeting room. After the position of the speaker is estimated by a speaker tracking system, we construct a subband-domain beamf ...

Speaker recognition in noisy environments using auxiliary information and Bayesian networks

Speaker recognition systems achieve acceptable performance in controlled laboratory conditions. However, in real-life environments, the performance of a speaker recognition system degrades drastically, the principal cause being the mismatch that exists bet ...

Joint speech and speaker recognition

The goal of the thesis is to investigate different approaches that combine and integrate Automatic Speech Recognition (ASR) and Speaker Recognition (SR) systems, with applications to (1) User-Customized Password Speaker Verification (UCP-SV) systems, and, ...
