Good Vibrations and Unknown Excitations
Dalia Salem Hassan Fahmy El Badawy
Inspired by the human ability to localize sounds, even with only one ear, as well as to recognize objects using active echolocation, we investigate the role of sound scattering and prior knowledge in regularizing ill-posed inverse problems in acoustics. In ...
EPFL2020Shapes From Echoes: Uniqueness From Point-to-Plane Distance Matrices
Martin Vetterli, Ivan Dokmanic, Miranda Krekovic
We study the problem of localizing a configuration of points and planes from the collection of point-to-plane distances. This problem models simultaneous localization and mapping from acoustic echoes as well as the & x201C;structure from sound & x201D; app ...
2020Pyramic: Full Stack Open Microphone Array Architecture And Dataset
René Beuchat, Robin Scheibler, Corentin Ferry
In this paper we introduce an open source and reproducible microphone array hardware design and an anechoic dataset recorded with this array. The Pyramic array has 48 microphones spread onto six identical modules connected to an FPGA-ARM combo. The arrange ...
IEEE2018Subjective evaluation of a spatialization feature for hearing aids by normal-hearing and hearing-impaired subjects
Hervé Lissek, Xavier Gigandet, Gilles André Courtois
Remote microphone systems significantly improve speech intelligibly performance offered by hearing aids. The voice of the speaker(s) is captured close to the mouth by a microphone, then wirelessly sent to the hearing aids. However, the sound is rendered in ...
AES2018Localization of Sound Sources in a Room with One Microphone
Pierre Vandergheynst, Hervé Lissek, Helena Peic Tukuljac
Estimation of the location of sound sources is usually done using microphone arrays. Such settings provide an environment where we know the difference between the received signals among different microphones in the terms of phase or attenuation, which enab ...
Spie-Int Soc Optical Engineering2017A 4.7μW switched-bias MEMS microphone preamplifier for ultra-low-power voice interfaces
This paper presents a switched-bias MEMS microphone preamplifier for an ultra-low-power voice interface. A switched-MOSFET periodically changes the MOSFET between strong inversion and accumulation to inherently reduce 1/f noise. In addition, a proposed cou ...
IEEE2017Pyramic array: An FPGA based platform for multi-channel audio acquisition
Microphone arrays techniques present compelling applications for robotic applications. Those techniques can allow robots to listen to their environment and infer clues from it. Such features might enable capabilities such as natural interaction with humans ...
