Abstract

Cette invention concerne un procédé de réglage de niveau de volume sur la base de l'environnement ambiant et un lecteur audio. Ledit procédé comprend : l'enregistrement d'un ou plusieurs ensembles de corrélations définies par un utilisateur, entre des intervalles d'intensité sonore d'un environnement ambiant et des décibels de volume pour la reproduction de musique (S101) ; la compilation de statistiques sur les intensités sonores de l'environnement ambiant au cours d'une période de temps déterminée (S102) ; le calcul de la moyenne des intensités sonores de l'environnement ambiant pendant la période de temps déterminée (S103) ; la détermination du fait que oui ou non la moyenne des intensités sonores de l'environnement ambiant pendant la période de temps déterminée est dans un intervalle d'intensité sonore de l'environnement ambiant défini par un utilisateur (S104) ; si ce n'est pas le cas, l'alerte de l'utilisateur (S105) ; et si c'est le cas, la reproduction de la musique aux décibels de volume correspondant à la période d'intensité sur la base de l'intervalle d'intensité sonore de l'environnement ambiant dans lequel se trouve la moyenne (S106). Au moyen des corrélations prédéfinies par l'utilisateur entre les intervalles d'intensité sonore de l'environnement ambiant et les décibels de volume pour la reproduction de musique, la moyenne des intensités sonores de l'environnement ambiant pendant une certaine période de temps est calculée, de telle sorte que le niveau de volume fourni en sortie par le lecteur audio puisse être réglé sur la base de l'intensité sonore moyenne de l'environnement actuel.
