Abstract

Casque stéréophonique comportant des écouteurs, de préférence du type fermé ou semi-fermé, qui sont reliés respectivement à un espace sonore pour un générateur électro-acoustique, les espaces sonores étant en outre reliés acoustiquement par un ou plusieurs tubes acoustiques. Dans chaque espace sonore 2 débouche un tube acoustique (différentiel) 3 dans lequel le son de l'autre espace sonore se propage dans un laps de temps correspondant à la propagation rectiligne du son sur une distance de déflexion normale de 15 à 25 cm, de préférence de 20 cm. L'invention est applicable à la reproduction du son par casque
