Understanding speech in noise is particularly difficult for individuals occupationally exposed to due a mix between noise-induced auditory lesions and energetic masking of signal. For years, the monitoring conventional audiometric thresholds has been usual way check preserve function. But highlighting supra-threshold deficits, notably understanding difficulties, pointed out need new tools.

This paper proposes a first attempt to visualize and analyze the vibrations induced by bone-conduction device propagating at surface of skin human face. The method is based on new approach in so-called quasi-time-averaging regime, resulting retrieval vibration amplitude phase from sequence digital Fresnel holograms recorded with high image rate. design algorithm depends ratio between exposure time period. results show propagation surface, quantitative analysis achieved proposed approach.

Sounds in our environment like voices, animal calls or musical instruments are easily recognized by human listeners. Understanding the key features underlying this robust sound recognition is an important question auditory science. Here, we studied listeners of new classes sounds: acoustic and sketches, sounds that severely impoverished but still recognizable. Starting from a time-frequency representation, sketch obtained keeping only sparse elements original signal, here, means simple...

Abstract Human listeners are able to recognize accurately an impressive range of complex sounds, such as musical instruments or voices. The underlying mechanisms still poorly understood. Here, we aimed characterize the processing time needed a natural sound. To do so, by analogy with “rapid visual sequential presentation paradigm”, embedded short target sounds within rapid sequences distractor sounds. core hypothesis is that any correct report implies sufficient for recognition had been...

Classical timbre studies have modeled as the integration of a limited number auditory dimensions and proposed acoustic correlates to these explain sound identification. Here, goal was highlight time-frequency patterns subserving identification musical voices instruments, without making any assumption about patterns. We adapted “random search method” in vision. The method consists synthesizing sounds by randomly selecting “auditory bubbles” (small glimpses) from original sounds’ spectrograms,...

Recently, suprathreshold deficits, notably, difficulties understanding noise, pointed out need new tools.

Since its creation, the coordinate response measure (CRM) corpus has been applied in hundreds of studies to explore mechanisms informational masking multi-talker situations, but also speech-in-noise or auditory attentional tasks. Here, we present French version, with equivalent content original version English. Furthermore, an evaluation speech-on-speech intelligibility shows similar result patterns data This validation CRM allows propose use for tests French, and comparisons a foreign...

Hearing loss is a major public health problem. In 2050, it could affect 2.5 billion people. It has therefore become necessary to prevent and diagnose them as early widely possible. However, the costs of clinical equipment dedicated functional exploration hearing remain high hamper their distribution, while technologies used are relatively basic. For example, gold-standard pure-tone audiometry (PTA) essentially consists emitting pure sounds. addition, audiometers generally limited PTA or few...

This paper proposes a first attempt to visualize and analyze the vibrations induced by bone-conduction device propagating at surface of human skin. The method suggested is based on so-called "quasi-time-averaging regime" resulting in retrieval vibration amplitude phase from sequence digital Fresnel holograms, recorded with high image rate.

We propose a new type of interaction dedicated to virtual reality (VR). have designed futuristic scenario promoting dialogue with humanoid. The participant is submitted reverse Turing test and has answer questions addressed by the uses his/her own voice respond, which transformed in real time terms timbre spatialization, correspondence special effects applied 360-degree video. Behavioral assessments are proposed after each vocal given, determine quality interaction. Overall, potential this...

Sounds in our environment like voices, animal calls, or musical instruments can be recognized on the basis of timbre alone. The objective this study was to unravel features underlying robust sound recognition. We investigated how severely sounds simplified while still being recognizable. A large number natural were into “auditory acoustic sketches:” energy peaks selected auditory spectrogram, at three levels simplification (high, medium, and low). remaining non-sparse information removed....

This paper proposes a first attempt to visualize and analyze the vibrations propagating at surface of human face's skin induced by bone conduction device. The proposed method allows qualitative visualization quantitative measurement movements illuminated coherent laser beam. To do this, we developed new approach in so-called "quasi-time-averaging regime" allowing retrieval vibration amplitude phase from sequence digital Fresnel holograms recorded with high image rate. experimental set-up is...
