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

Hervé Lissek, Xavier Falourd, 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 ...

A sound diffusion system for directional sound enhancement

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

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

Jean-Marc Odobez, Hervé Lissek, Xavier Falourd, 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

Jean-Marc Odobez, Hervé Lissek, Xavier Falourd, 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 ...

Device and method for capturing and processing voice

Hervé Lissek, Xavier Falourd, Patrick Marmaroli, Philippe Martin

A portable voice capture device comprising: an orientable arm with a first differential array of microphones comprising at least one pair of microphones, the directivity of said first array being arranged for sensing voice from a first direction depending ...

Practical 3 dimensional sound reproduction using Wave Field Synthesis, theory and perceptual validation

Hervé Lissek, Xavier Falourd, Lukas Rohr

Sound ﬁeld reproduction using Wave Field Synthesis has been so far limited to the positioning of virtual sources and listeners in the horizontal plane only although the underlying formulation (Kirchhoﬀ-Helmholtz) describes the reproduction of 3 dimensional ...

A Comparative Study of Time Delay Estimation Techniques for Road Vehicle Tracking

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

This paper addresses road traffic monitoring using passive acoustic sensors. Recently, the feasibility of the joint speed and wheelbase length estimation of a road vehicle using particle filtering has been demonstrated. In essence, the direction of arrival ...

A UAV Motor Denoising Technique to Improve Localization of Surrounding Noisy Aircrafts: Proof of Concept for Anti-Collision Systems

Hervé Lissek, Xavier Falourd, Patrick Marmaroli

Unmanned Aerial Vehicles (UAVs) have become very affordable and small in recent years, and are increasingly used in a wide range of monitoring and surveillance applications. A major problem when operating with swarm of UAVs is the risk of mid-air collision ...

Melanic color-dependent antipredator behavior strategies in barn owl nestlings

Xavier Falourd

The arms race between predators and prey has led to morphological and behavioral adaptations. Different antipredator strategies can coexist within a population if each strategy is the result of a trade-off with competing demands. Antipredator behavior can ...
