No need to shout: Effect of signal loudness on sibling communication in barn owls

Xavier Falourd, Hervé Lissek, Patrick Marmaroli, Dorian Cazau

In animal communication, signal loudness is often ignored and seldom measured. We used a playback experiment to examine the role of vocal loudness (i.e., sound pressure level) in sibling to sibling communication of nestling barn owls Tyto alba. In this spe ...

Hearing assistance system

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

There is provided a hearing assistance system, comprising a transmission unit (10) comprising a microphone arrangement (17) for capturing audio signals from a voice of a speaker ( 11 ) using the transmission unit and being adapted to transmit the audio sig ...

Dynamic Range Limiting of HRTFs: Principle and Objective evaluation

Hervé Lissek, Lukas Rohr, Patrick Marmaroli, Gilles André Courtois

This research addresses the challenge of incorporating dynamic range limiting of the magnitude response of HRTFs for hearing-impaired listeners who are using binaural hearing aids. In this application, a direct implementation of spatialization using the or ...

Body part-centered and full body-centered peripersonal space representations

Hervé Lissek, Olaf Blanke, Patrick Marmaroli, Jean-Paul Noel, Andrea Serino, Elisa Canzoneri

Dedicated neural systems represent the space surrounding the body, termed Peripersonal space (PPS), by integrating visual or auditory stimuli occurring near the body with somatosensory information. As a behavioral proxy to PPS, we measured participants' re ...

Development and assessment of a localization algorithm implemented in binaural hearing aids

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

Digital wireless microphone systems have been developed to enhance speech intelligibility for hearing aid users. The voice of the speaker of interest is picked-up close to the mouth by a body-worn microphone, and rendered in a diotic way (same signal at th ...

Full body action remapping of peripersonal space: The case of walking

Hervé Lissek, Olaf Blanke, Petr Grivaz, Patrick Marmaroli, Jean-Paul Noel, Andrea Serino

The space immediately surrounding the body, i.e. peripersonal space (PPS), is represented by populations of multisensory neurons, from a network of premotor and parietal areas, which integrate tactile stimuli from the body’s surface with visual or auditory ...

A sound diffusion system for directional sound enhancement

Xavier Falourd, Hervé Lissek, Alexandre Delidais, Alain Dufaux, Baptiste Crettaz, Patrick Marmaroli, Cédric Monchâtre

A loudspeaker array is described including several circular sound emitters that are bunked. One circular sound emitter can be either a circular array of loudspeakers (kind 1) or a toroidal loudspeaker (kind 2). The loudspeaker array can be composed of circ ...

Implementation of a binaural localization algorithm in hearing aids: Specifications and achievable solutions

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

This article introduces the constraints and issues related to the implementation of a binaural localization algorithm on a pair of hearing aids. The algorithm should improve the rendering of the spatial information available in the audio signals, which are ...

Bimodal sound source tracking applied to road traffic monitoring

Patrick Marmaroli

The constant increase of road traffic requires closer and closer road network monitoring. The awareness of traffic characteristics in real time as well as its historical trends, facilitates decision-making for flow regulation, triggering relief operations, ...

Pass-by noise acoustic sensing for estimating speed and wheelbase length of two-axle vehicles

Xavier Falourd, Hervé Lissek, Jean-Marc Odobez, Patrick Marmaroli

This paper focuses on acoustic road traffic monitoring and looks, more specifically, into the problem of speed and wheelbase length estimation of two-axle vehicles as they pass by. It is known that both front and rear axle trajectories may be dissociated u ...

Observation of Vehicle Axles Through Pass-by Noise: A Strategy of Microphone Array Design

Xavier Falourd, Hervé Lissek, Jean-Marc Odobez, Patrick Marmaroli

This paper focuses on road traffic monitoring using sounds and proposes, more specifically, a microphone array design methodology for observing vehicle trajectory from acoustic-based correlation functions. In a former work, authors have shown that combinin ...

A Bimodal Sound Source Model for Vehicle Tracking in Traffic Monitoring

Xavier Falourd, Hervé Lissek, Jean-Marc Odobez, Patrick Marmaroli

The paper addresses road traffic monitoring using a compact microphone array. More precisely, estimation of both speed and wheelbase distance of detected vehicles is performed. The detection algorithm is based on the comparison between theoretical and meas ...

Study of an octahedral antenna for both sound pressure level estimation and 3D localization of multiple sources

Xavier Falourd, Hervé Lissek, Patrick Marmaroli

This study deals with localization and characterization of multiple sources by mean of an octahedral array processing. We show how correlations enable to both localize more sources that the number of sensors and estimate their sound level pressure simultan ...
