Description

Système d’adaptateur de communication pour filtre acoustique de protecteur individuel avec mixage des sons extérieursCommunication adapter system for personal protector acoustic filter with mixing of external sounds

Le problème de la communication dans le bruit reste une préoccupation importante des personnels exposés pour leur sécurité et la bonne exécution des consignes vocales. À partir d’un certain niveau de bruit la réglementation européenne impose le port de protections auditives ayant les caractéristiques adéquates et l’atténuation nécessaire pour mettre en sécurité l’audition des personnels. Il existe des protections auditives individuelles contenant des filtres acoustiques permettant de filtrer en partie les sons et de favoriser la compréhension de la parole mais à partir d’un certain niveau de bruit et notamment à partir de plus de 95 dB, la communication verbale devient de toute façon impossible; les protecteurs continuent de protéger mais la perception formelle de la voix d’un interlocuteur pour la sécurité ou des instructions devient approximative.The problem of communication in noise remains a major concern for exposed personnel for their safety and the proper execution of voice instructions. From a certain level of noise, European regulations require the wearing of hearing protection with the appropriate characteristics and the attenuation necessary to protect the hearing of personnel. There are individual hearing protectors containing acoustic filters to partially filter the sounds and promote understanding of speech, but from a certain noise level and in particular from more than 95 dB, verbal communication becomes difficult. anyway impossible; the protectors continue to protect but the formal perception of the voice of an interlocutor for security or instructions becomes approximate.

Toute une famille de produit antibruit connectés filaire ou radio est alors nécessaire de façon à transmettre les informations vocales de manière intelligible, ces équipements sont très généralement des casques antibruit adaptés et transformés de façon à intégrer l’électronique de communication, hautparleur, micro et ampli.A whole family of wired or radio-connected noise canceling products is then necessary in order to transmit voice information intelligibly. .

Actuellement, pour les utilisateurs d’EPI antibruit auriculaire individuelle comme les bouchons d’oreilles standards ou moulés sur mesure avec filtre acoustique, il n’existe pas de solution simple qui ne dégrade pas l’EPI (Équipement de Protection Individuel), car une solution souvent utilisée est le perçage d’un deuxième canal parallèle au filtre acoustique afin de relier directement l’oreille à un tube acoustique souvent spiralé, lui-même relié à un écouteur issu d’une radio ou système de communication. Si on réalise cette modification, l’EPI antibruit de catégorie III qui doit-être obligatoirement certifié par un organisme notifié suivant la norme EN 352-2 perd de fait sa certification et ne peut se prévaloir de la dénomination d’antibruit suivant la réglementation Européenne.Currently, for users of personal ear protection PPE such as standard or custom molded earplugs with acoustic filters, there is no simple solution that does not degrade the PPE (Personal Protective Equipment), because a The solution often used is the drilling of a second channel parallel to the acoustic filter in order to directly connect the ear to an often spiral acoustic tube, itself connected to an earpiece from a radio or communication system. If this modification is made, category III noise-canceling PPE which must be certified by a notified body according to standard EN 352-2 in fact loses its certification and cannot claim the designation of noise-canceling according to European regulations. .

L’invention décrite ci-après permet la fabrication suivant ces recommandations d’un adaptateur fournissant une solution adaptée à l’environnement sonore et à l’utilisation de l’EPI sans modification. Nous prendrons pour l’exemple un antibruit standard avec filtre acoustique (Fig1.F) décrit par le Brevet Européen 2469734, le système peut être transposé à d’autres produits en prenant soin d’ajuster les dimensions.The invention described below allows the manufacture according to these recommendations of an adapter providing a solution adapted to the sound environment and to the use of the PPE without modification. We will take for example a standard noise canceling with acoustic filter (Fig1.F) described by the European Patent 2469734, the system can be transposed to other products by taking care to adjust the dimensions.

L’adaptateur de communication (Fig1.1) pour filtre acoustique (Fig1.F) de protecteur individuel auriculaire (Fig1.E) est composé d’une partie permettant le couplage (Fig1.C) de l’entrée du filtre acoustique (Fig1.Fe) et d’un porte tube solidaire au système (Fig1.2) permettant par exemple la connexion d’un tube acoustique souple torsadé (Fig1.4). L’invention comprend un perçage sur cet adaptateur vers l’extérieur avec un diamètre (Fig1.3) de différentes dimensions. L’utilisateur choisira en fonction des niveaux sonores ambiants l’ouverture (fig2.1 à 3) correspondant au mieux à la compréhension des messages vocaux. Dans l’exemple figuré, 3 types d’adaptateurs sont proposés, l’intérêt du diamètre le plus ouvert est la meilleure écoute de l’environnement sonore puis, la meilleure écoute des messages vocaux transmis par le tube acoustique via la radio par le positionnement de l’index sur l’adaptateur afin de refermer l’ouverture du dit adaptateur. Pour des niveaux sonores forts l’adaptateur avec le plus petit trou apportera une meilleure compréhension des messages sonores passant en permanence par le tube acoustique au détriment de l’environnement sonore immédiat. Il est noté que l’EPI auriculaire par lui-même (Fig1.E) représenté ici par l’entrée du filtre acoustique n’est pas modifié et conserve toutes ces caractéristiques intrinsèques, le son extérieur comme le son du système de communication (Fig1.R) transmis par son écouteur (Fig1.e) via le tube spiralé (Fig1.4) passent par l’entrée du filtre qui filtrera le mixte des deux.The communication adapter (Fig1.1) for acoustic filter (Fig1.F) of individual hearing protector (Fig1.E) is composed of a part allowing the coupling (Fig1.C) of the input of the acoustic filter (Fig1 .Fe) and a tube holder integral with the system (Fig1.2) allowing for example the connection of a twisted flexible acoustic tube (Fig1.4). The invention includes a bore on this adapter outward with a diameter (Fig1.3) of different dimensions. The user will choose, depending on the ambient sound levels, the aperture (figs 2.1 to 3) that best suits the understanding of voice messages. In the example shown, 3 types of adapters are proposed, the advantage of the most open diameter is the best listening to the sound environment then, the best listening to the voice messages transmitted by the acoustic tube via the radio by the positioning index on the adapter to close the opening of said adapter. For loud sound levels, the adapter with the smallest hole will provide better understanding of the sound messages constantly passing through the acoustic tube to the detriment of the immediate sound environment. It is noted that the ear PPE by itself (Fig1.E) represented here by the input of the acoustic filter is not modified and retains all these intrinsic characteristics, the external sound like the sound of the communication system (Fig1 .R) transmitted by its earphone (Fig1.e) via the spiral tube (Fig1.4) pass through the inlet of the filter which will filter the mixture of the two.
