Neuroimaging of human auditory cortex : data analysis and applications

Naghmeh Ghazaleh

Modern neuroimaging technologies provide us with non-invasive methods for study- ing structure and function, and plasticity of the human auditory cortex. Here we have acquired high spatial resolution functional magnetic resonance imaging (fMRI) data of the ...

Omnidirectional bats, point-to-plane distances, and the price of uniqueness

Martin Vetterli, Ivan Dokmanic, Miranda Krekovic

We study simultaneous localization and mapping with a device that uses reflections to measure its distance from walls. Such a device can be realized acoustically with a synchronized collocated source and receiver; it behaves like a bat with no capacity for ...

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 ...

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, Patrick Marmaroli, Gilles André Courtois, Lukas Rohr

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 ...

Human audiometric thresholds do not predict specific cellular damage in the inner ear

Demetri Psaltis

Introduction: As otology enters the field of gene therapy and human studies commence, the question arises whether audiograms - the current gold standard for the evaluation of hearing function - can consistently predict cellular damage within the human inne ...

Surgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal

Demetri Psaltis, Simon Nessim Henein

Objective: To enable development of an endoscope for cellular-level optical imaging of the inner ear. Study Design: A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range o ...

Objective and subjective validation of an active control approach to reduce the occlusion effect in hearing aids

Hervé Lissek, Thomas Stefan Zurbrügg

The occlusion effect refers to the altered perception of one's own voice when the ear canal is fully or partially obstructed. Conventional countermeasures include the use of large vent bores or open fittings on the one hand and fittings reaching as deep as ...

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 ...
