Title (EN) LISTENING DEVICE FOR CLEAR PERCEPTION OF SOUND SIGNALS IN A NOISY ENVIRONMENT
(FR) DISPOSITIF AUDITIF PERMETTANT LA PERCEPTION CLAIRE DE SIGNAUX ACOUSTIQUES DANS UN ENVIRONNEMENT BRUYANT
Abstract:
(EN) The invention concerns a listening device (1) for transmitting electroacoustic signals comprising an earphone (2) and means for connecting said earphone (2) with a remote electroacoustic source (3). The invention is characterized in that it comprises an acoustic filter (4) and that its shape is perfectly adapted to the external auditory canal of the ear so as to provide sufficient soundproofing to the external environment. The invention also concerns a headphone comprising one or two such listening devices.
(FR) Oreillette (1 ) pour la transmission de signaux électro-acoustiques comprenant un écouteur (2) et des moyens de connexion pour connecter ledit écouteur (2) avec une source électro-acoustique distante (3), caractérisée en ce qu'elle comprend un filtre acoustique (4) et en ce que sa forme s'adapte parfaitement au conduit auditif externe de l'oreille de manière à assurer une insonorisation suffisante avec l'environnement externe. L'invention se rapporte également à un casque comportant une ou deux oreillettes telles que précédemment décrites.
