Abstract

Un dispositif de commande du volume sonore (100) comprend une unité de détection de position (101), une unité de détection de lieu (102), une unité de calcul de distance (103) et une unité de commande du volume sonore de sortie (104). L'unité de détection de position (101) détecte une position d'un corps en déplacement. L'unité de détection de lieu (102) détecte un lieu de guide sur un tracé de guidage du corps en mouvement. L'unité de calcul de distance (103) calcule une distance entre le point de guidage et le corps en déplacement sur la base des informations de position détectées par l'unité de détection de position (101) et du lieu de guide détecté par l'unité de détection de lieu (102). L'unité de commande du volume sonore de sortie (104) réduit le volume sonore de sortie d'un dispositif d'émission de son lorsque le corps en déplacement s'approche du lieu de guide. En outre, lorsque la distance entre la position du corps en déplacement, qui a dépassé le lieu de guide, et le lieu de guide suivant est en dessous d'une valeur de seuil, l'unité de commande du volume sonore de sortie (104) continue à réduire le volume sonore de sortie du dispositif d'émission de son jusqu'à ce que le corps en déplacement dépasse le lieu de guide suivant.
