Bimodal sound source tracking applied to road traffic monitoring

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, ...

Tuning In to Sound: Frequency-Selective Attentional Filter in Human Primary Auditory Cortex

Melissa Saenz, Wietske Van der Zwaag, Stephanie Clarke

Cocktail parties, busy streets, and other noisy environments pose a difficult challenge to the auditory system: how to focus attention on selected sounds while ignoring others? Neurons of primary auditory cortex, many of which are sharply tuned to sound fr ...

Echo thresholds for reflections from acoustically diffusive architectural surfaces

Christof Faller, Andreas Walther

When sound reflects from an irregular architectural surface, it spreads spatially and temporally. Extensive research has been devoted to prediction and measurement of diffusion, but less has focused on its perceptual effects. This paper examines the effect ...

Influence of reflecting walls on edge diffraction simulation in geometrical acoustics

Dirk Schröder

Edge diffraction can be introduced into Geometrical Acoustics mainly by three models: detour-based, energetic and wave-based diffraction models. In the past, we thoroughly compared Maekawa's detour law, the uncertainty relation based diffraction method and ...

Social modulation of peripersonal space boundaries

Andrea Serino

The space around the body, i.e., peripersonal space (PPS), is conceived as a multisensory-motor interface between body and environment. PPS is represented by frontoparietal neurons integrating tactile, visual, and auditory stimuli occurring near the body [ ...

Experimental study of z resolution in acousto-optical coherence tomography using random phase jumps on ultrasound and light

Salma Farahi

Acousto-optical coherence tomography (AOCT) is a variant of acousto-optic imaging (also called ultrasound modulated optical tomography) that makes possible to get resolution along the ultrasound propagation axis z. We present here AOCT experimental results ...

Auditory perceptual decision-making based on semantic categorization of environmental sounds

Fosco Bernasconi, Athina Tzovara

Discriminating complex sounds relies on multiple stages of differential brain activity. The specific roles of these stages and their links to perception were the focus of the present study. We presented 250 ms duration sounds of living and man-made objects ...

Advanced control for modifying the acoustic impedance at the diaphragm of a loudspeaker

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

The control of low-frequency sound fields can be addressed efficiently through acoustic impedance matching. Basically, the diaphragm of electroacoustic transducers are used as refracting surface that controls the reaction of the boundaries in any surroundi ...

Practical realization of «smart acoustic materials» by controlling a loudspeaker with the help of a cRIO platform

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

This presentation describes how to practically implement a digital controller using the compactRIO real-time platform in order to use of a loudspeaker as an electroacoustic absorber for better sound control in listening rooms. ...

Robust Acoustic Source Localization of Emergency Signals from Micro Air Vehicles

Dario Floreano, Felix Stephan Schill, Meysam Basiri

In search and rescue missions, Micro Air Vehicles (MAV's) can assist rescuers to faster locate victims inside a large search area and to coordinate their efforts. Acoustic signals play an important role in outdoor rescue operations. Emergency whistles, as ...
