Abstract

Un dispositif de contrôle (DC) équipe un système (V) comprenant un espace (H) propre à accueillir au moins une personne, un appareil de reproduction sonore (AR) pour diffuser des sons selon une intensité choisie dans cet espace (H) et au moins un microphone (MP) captant des sons dans cet espace (H). Ce dispositif (DC) comprend des moyens d'analyse (MA) déterminant un niveau d'exposition au bruit dans l'espace (H) à partir des sons captés dans ce dernier (H), et des moyens de contrôle (MC) déterminant si ce niveau déterminé est supérieur à un seuil, et, dans l'affirmative, ordonnant à l'appareil de reproduction sonore (AR) de diffuser leurs sons selon une nouvelle intensité strictement inférieure à l'intensité choisie.A control device (DC) equips a system (V) comprising a space (H) suitable for accommodating at least one person, a sound reproduction device (AR) for diffusing sounds according to a selected intensity in this space (H) and at least one microphone (MP) picking up sounds in this space (H). This device (DC) comprises analysis means (MA) determining a level of exposure to noise in space (H) from the sounds picked up in the latter (H), and control means (MC) determining if this determined level is above a threshold, and, if so, ordering the sound reproduction apparatus (AR) to broadcast their sounds at a new intensity strictly lower than the chosen intensity.
