Hearing structure in music: An empirical inquiry into listening as representation and processing

As a universal expression of human creativity, music is capable of conveying great subtlety and complexity. Crucially, this complexity is not encoded in the score or in the sounds, but is rather construed in the mind of the listener in the form of nuanced ...

Design of Remote Quiet Zones Using Spot-Type Sound Reducers

Hervé Lissek, Romain Boulandet, Thomas Laurence

This paper presents a local control approach to generate remote quiet zones. To deal with situations where global control can hardly be achieved, it is proposed to use an arrangement of spot-type sound reducers as originally suggested by Olson and May. Ass ...

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 ...

Protection Strategy against IEMI for Wireless Communication Infrastructures

Farhad Rachidi-Haeri, Marcos Rubinstein, Nicolas Mora Parra, Mirjana Stojilovic

In this paper, we present a methodology for estimating the protection levels of critical equipment against IEMI. We apply the method to a wireless communication infrastructure, but it can be applied to any critical infrastructure. The required protection l ...

On solving LPN using BKW and variants Implementation and Analysis

Serge Vaudenay, Sonia Mihaela Bogos, Florian Tramèr

The Learning Parity with Noise problem (LPN) is appealing in cryptography as it is considered to remain hard in the post-quantum world. It is also a good candidate for lightweight devices due to its simplicity. In this paper we provide a comprehensive anal ...

Spatial hearing rendering in wireless microphone systems for binaural hearing aids

Gilles André Courtois

In 2015, 360 million people, including 32 million children, were suffering from hearing impairment all over the world. This makes hearing disability a major worldwide issue. In the US, the prevalence of hearing loss increased by 160% over the past generati ...

Optimal Proximity Proofs

Serge Vaudenay

Provably secure distance-bounding is a rising subject, yet an unsettled one; indeed, very few distance-bounding protocols, with formal security proofs, have been proposed. In fact, so far only two protocols, namely SKI (by Boureanu et al.) and FO (by Fisch ...

Listening to Distances and Hearing Shapes : Inverse Problems in Room Acoustics and Beyond

Ivan Dokmanic

A central theme of this thesis is using echoes to achieve useful, interesting, and sometimes surprising results. One should have no doubts about the echoes' constructive potential; it is, after all, demonstrated masterfully by Nature. Just think about the ...

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 ...

Performance Improvement of TDOA-Based Speaker Localization in Joint Noisy and Reverberant Conditions

TDOA- (time difference of arrival-) based algorithms are common methods for speech source localization. The generalized cross correlation (GCC) method is the most important approach for estimating TDOA between microphone pairs. The performance of this meth ...

Nanoparticle conjugation and pulmonary delivery enhance the protective efficacy of Ag85B and CpG against tuberculosis

John McKinney, Neeraj Dhar, Jeffrey Alan Hubbell, Eleonora Simeoni, Melody Swartz, Cyntia De Piano, Alexandre de Titta, Marie Ballester, Miriella Carmela Pasquier

Vaccines that drive robust T-cell immunity against Mycobacterium tuberculosis (Mtb) are needed both for prophylactic and therapeutic purposes. We have recently developed a synthetic vaccine delivery platform with Pluronic-stabilized polypropylene sulfide n ...

On Noise Insertion Strategies for Wireless Network Secrecy

Emre Telatar, Suhas Diggavi, Etienne Perron

We provide lower and upper bounds on the optimal rate for reliable and secret transmission of a message from one node to another in an arbitrary wireless network with deterministic signal interaction. Certain relay nodes are allowed to insert noise into th ...

Plasma blobs in a basic toroidal experiment: Origin, dynamics, and induced transport

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Mario Ludovico Podesta

Detaching plasma blobs with very similar properties to tokamaks are observed in the basic toroidal plasma experiment TORPEX [ A. Fasoli et al., Phys. Plasmas 13, 055902 (2006) ]. The blobs originate from the breaking of wave crests of a drift-interchange w ...

Spatio-Temporal Sampling and Distributed Compression of the Sound Field

Martin Vetterli, Emre Telatar, Luciano Sbaiz, Olivier Roy, Thibaut Ajdler, Robert Konsbruck

We investigate how the sound field induced by an acoustic event evolves over space and time. The characteristics of its bidimensional Fourier spectrum are analyzed and spatio-temporal sampling results using an array of microphones are provided for differen ...

Architectural education for sustainable design - A proposal for improving indoor environment quality

Claude-Alain Roulet

Buildings should be comfortable and healthy. They are a shelter for their occupants and should not be a source of problems. The architect widely influences the indoor environment quality by his design,. Ensuring a good indoor environment through appropriat ...
