Bone conduction facilitates self-other voice discrimination

Olaf Blanke, Nathan Quentin Faivre, Oliver Alan Kannape, Pavo Orepic

One's own voice is one of the most important and most frequently heard voices. Although it is the sound we associate most with ourselves, it is perceived as strange when played back in a recording. One of the main reasons is the lack of bone conduction tha ...

EEG Spatiotemporal Patterns Underlying Self-other Voice Discrimination

Olaf Blanke, Pavo Orepic, Sixto Luis Alcoba Banqueri, Giannina Rita Iannotti, Thomas Koenig

There is growing evidence showing that the representation of the human “self” recruits special systems across different functions and modalities. Compared to self-face and self-body representations, few studies have investigated neural underpinnings specif ...

Dissecting self-voice perception: From bone conduction to robotically-induced self-other voice misattribution in healthy listeners

Pavo Orepic

Inspired by the prominent theory suggesting that auditory-verbal hallucinations (AVH) - the sensation of hearing voices without present speakers - arise as misattribution of inner speech towards external agents, my thesis revolved around self-voice percept ...

Equal Loss Distribution in Duty-Cycle Controlled H-Bridge LLC Resonant Converters

Drazen Dujic, Jakub Kucka

The duty-cycle control is a popular option for current limiting in LLC resonant converters. Such current limiting is required to protect the converter either during the start-up or during an overload. Although this method proved to be effective, the switch ...

Imaging hair cells through laser-ablated cochlear bone

Demetri Psaltis, Ye Pu, Marilisa Romito

We report an innovative technique for the visualization of cells through an overlying scattering medium by combining femtosecond laser bone ablation and two-photon excitation fluorescence (TPEF) microscopy. We demonstrate the technique by imaging hair cell ...

Inner ear cellular imaging through scattering bone

Demetri Psaltis, Marilisa Romito

Inner ear imaging is important for the assessment of hearing disorders. A major cause of hearing loss is the damage to the sensory hair cells, which are located inside the cochlea, a spiral-shaped bone in the inner ear. Imaging of intracochear hair cells i ...

Biomedical optical techniques for intracochlear cellular imaging

Marilisa Romito

Imaging the inner ear microanatomy is of great importance for the assessment of the state of the cells responsible for sound detection. Hearing disorders are mainly due to a malfunction of the cochlea, the bone containing the cells inside the inner ear. Un ...

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 ...

Design of a Semi-Implantable Hearing Device for Direct Acoustic Cochlear Stimulation

Yves Perriard, Hans Bernhard

A new hearing therapy based on direct acoustic cochlear stimulation was developed for the treatment of severe to profound mixed hearing loss. The device efficacy was validated in an initial clinical trial with four patients. This semi-implantable investiga ...

Design Methodology and Innovative Device Concept for Acoustic Hearing Implants

Hans Bernhard

Nowadays, hearing impaired people can be treated with a multitude of different devices and surgical interventions that are selected in function of the type and degree of hearing loss of the patient. These known therapies cover the major part of possible he ...
