Abstract

L'invention porte sur un système de réduction du bruit installé dans un siège, ce siège comprenant, en combinaison, un haut-parleur et un microphone montés, dans une position fixe, adjacents à l'oreille d'un utilisateur, cette combinaison haut-parleur/microphone pouvant se régler par rapport à l'oreille de l'utilisateur. Le haut-parleur et le microphone peuvent être montés dans les extensions de l'appui-tête du siège.
