Abstract

L’invention concerne un dispositif réflecteur acoustique (10) pour plaque de protection sanitaire (2) plane transparente s’étendant sensiblement verticalement, le dispositif réflecteur acoustique (10) comprenant un réflecteur acoustique (11) comprenant une surface de réflexion (12) et des moyens de montage (13) permettant de maintenir la surface de réflexion (12) dans une configuration opérationnelle par rapport à la plaque de protection (2), dans laquelle la surface de réflexion est apte à réfléchir une onde acoustique de fréquence comprise entre 200 Hz et 8 kHz émise depuis une première position jusqu’à une deuxième position séparée de la première position par la plaque de protection (2), et réciproquement. Figure pour l’abrégé : Fig 1.The invention relates to an acoustic reflector device (10) for a transparent flat sanitary protection plate (2) extending substantially vertically, the acoustic reflector device (10) comprising an acoustic reflector (11) comprising a reflection surface (12) and mounting means (13) making it possible to maintain the reflection surface (12) in an operational configuration relative to the protection plate (2), in which the reflection surface is capable of reflecting an acoustic wave of frequency between 200 Hz and 8 kHz transmitted from a first position to a second position separated from the first position by the protection plate (2), and vice versa. Figure for abstract: Fig 1.
