Abstract

L'invention concerne un procédé pour l'amélioration de la compréhension dans le bruit. Selon l'invention, les aides auditives sont munies de microprocesseurs permettant l'analyse de la localisation spatiale des éléments bruyants, les informations sont transmises à un Smartphone ou une télécommande, ce qui permet la visualisation sur un écran des différentes sources sonores et leurs provenances (voix, chant, moteur, bruits d'impacts...) sous forme d'un plan. Figure 1. La personne choisit en cliquant directement sur le plan, la ou les sources qu'elle veut accentuer , diminuer ou annuler afin que les aides auditives modifient leurs algorithmes pour accentuer la puissance des sources choisies et réduire les autres sources sonores Figure 2. L'application est particulièrement adaptée aux aides auditives et aux aides à l'écoute pour améliorer la compréhension dans le bruit.The invention relates to a method for improving understanding in noise. According to the invention, the hearing aids are equipped with microprocessors for analyzing the spatial location of the noisy elements, the information is transmitted to a smartphone or a remote control, which allows viewing on a screen of different sound sources and their sources (voice, song, motor, impact sounds ...) in the form of a plan. Figure 1. The person chooses by clicking directly on the plan, the source or sources that it wants to accentuate, reduce or cancel so that the hearing aids modify their algorithms to accentuate the power of the chosen sources and reduce the other sound sources Figure 2. The application is particularly suitable for hearing aids and listening aids to improve understanding in noise.

Description

Procédé pour l’amélioration de la compréhension dans le bruit L’audition naturelle permet de percevoir des sources sonores et le système cognitif de chaque individu permet d’en faire la localisation dans l’espace, l’être humain est capable de se concentrer sur une source particulière, et ainsi comprendre un interlocuteur dans le bruit.Process for improving understanding in noise Natural hearing allows us to perceive sound sources and the cognitive system of each individual makes it possible to locate it in space, the human being is able to concentrate on a particular source, and thus include an interlocutor in the noise.

Les mal-entendants ou toute personne située dans un environnement trop bruyant n’arriveront pas à séparer intellectuellement les différentes sources du bruit.The hearing impaired or anyone in a noisy environment will not be able to intellectually separate the different sources of noise.

Les aides auditives, grâce aux microphones directionnels, arrivent à favoriser l’audition pour des sources sonores venant d’en face.Hearing aids, thanks to the directional microphones, are able to favor hearing for sound sources coming from the other side.

La possibilité de mixage d’une même source sonore par les appareils droit et gauche permet l’hyper directivité en appliquant des masques successifs.The possibility of mixing the same sound source by the right and left devices allows hyper directivity by applying successive masks.

Ces solutions permettent, par exemple, une focalisation du son central pour que l’auditeur puisse se concentrer sur l’intervenant situé en face de lui.These solutions allow, for example, a focus of the central sound so that the listener can focus on the speaker in front of him.

Par ailleurs, le réhausseur de la voix la plus forte permet d’accentuer la voix de la personne qui parle le plus fort dans le bruit.In addition, the booster of the loudest voice can accentuate the voice of the person who speaks loudest in the noise.

Le « Noise canceler » principe d’annulation des bruits constants est basé sur l’opposition de phase. En réinjectant la source sonore en opposition de phase, les ondes sonores s’annulent, ce qui permet de retirer un bruit constant. Ce principe fonctionne très bien quand le bruit est constant ce qui n’est pas le cas dans les conversations de groupe ou avec les bruits d’impact.The "Noise canceler" principle of cancellation of constant noise is based on the phase opposition. By re-injecting the sound source in phase opposition, the sound waves cancel each other out, which makes it possible to remove a constant noise. This principle works very well when the noise is constant which is not the case in group conversations or with impact noises.

Malheureusement si la personne que vous désirez écouter n’est ni la plus bruyante, ni en face et que le bruit environnant n’est pas constant, aucun de ces procédés ne permet d’améliorer votre compréhension dans le bruit. L’invention permet de remédier à ces inconvénients.Unfortunately, if the person you want to listen to is neither the loudest nor the loudest and the surrounding noise is not constant, none of these processes can improve your understanding of noise. The invention overcomes these disadvantages.

Certaines aides auditives ou aides à l’écoute permettent le mixage des 2 aides auditives grâce à une communication entre les 2 appareils. Ces appareils sont munis de 2 microphones chacun. Ce système permet de réaliser une cartographie circulaire des différentes sources sonores par comparaison des 4 transducteurs d’entrée : Avant Droit, Avant gauche, Arrière Droit, Arrière Gauche. En utilisant soit le déphasage des sources, soit la différence de puissances, on peut définir l’angle et la distance. L’angle est précis, et la distance n’est qu’approximative. Les aides auditives modernes permettent de communiquer avec les Smartphones, soit pour recevoir le son du Smartphone (Téléphone, Musique, Microphone supplémentaire, message d’alerte), soit pour servir de télécommande (plus fort, plus faible, changement de programme).Some hearing aids or listening aids allow the mixing of 2 hearing aids thanks to a communication between the 2 devices. These devices are equipped with 2 microphones each. This system allows a circular mapping of the different sound sources by comparing the 4 input transducers: Front Right, Left Front, Right Rear, Left Rear. By using either the phase shift of the sources or the difference in power, we can define the angle and the distance. The angle is precise, and the distance is only approximate. Modern hearing aids make it possible to communicate with smartphones, either to receive the sound of the Smartphone (telephone, music, additional microphone, warning message), or to act as a remote control (louder, weaker, change of program).

Les aides auditives intra auriculaires permettent également la cartographie mais n‘utilisent qu’un microphone par aide auditive.Intra-ear hearing aids also allow for mapping but use only one hearing aid microphone.

Le procédé consiste à retranscrire sur le Smartphone, sous forme d’une carte les différentes sources sonores situées autour de la personne Figure 1.The method consists in retranscribing on the Smartphone, in the form of a map, the different sound sources located around the person Figure 1.

La personne sélectionne chacune des sources sonores qu’il souhaite accentuer, diminuer ou annuler, en cliquant sur sa représentation sur l’écran du Smartphone.The person selects each of the sound sources that he wishes to accentuate, reduce or cancel, by clicking on his representation on the screen of the Smartphone.

Dans une forme particulière le choix ne sera que d’augmenter les sources choisies. Figure 2In a particular form the choice will only increase the sources chosen. Figure 2

Dans une autre forme le choix ne sera que de baisser les sources choisies.In another form the choice will only be to lower the chosen sources.

Dans une autre forme le choix ne sera que d’annuler les sources choisies.In another form the choice will only be to cancel the chosen sources.

Le Smartphone transmet aux aides auditives ou aides à l’écoute, les commandes pour modifier la puissance des sources choisies; les augmenter, les abaisser ou les annuler.The Smartphone transmits to the hearing aids or listening aids, the commands to modify the power of the chosen sources; raise, lower or cancel them.
