L’effet Lombard indique que si le bruit augmente de 1 dB, le niveau de la parole augmente \u00e9galement de 0,5 dB. Dans un environnement bruyant, les personnes qui parlent augmentent donc le volume ou la hauteur de leur discours. Plus il y a de personnes dans une pi\u00e8ce, plus le niveau de bruit g\u00e9n\u00e9ral est \u00e9lev\u00e9, par exemple dans les restaurants ou les centres d’appel.<\/p>

Plus simplement, l’effet Lombard d\u00e9crit l’effet du bruit sur la production de la parole : lorsqu’un orateur est expos\u00e9 au bruit, il augmente le volume de son discours afin de pouvoir encore se faire comprendre de son interlocuteur dans l’environnement bruyant. Cependant, le locuteur augmente g\u00e9n\u00e9ralement non seulement son volume, mais aussi, dans de nombreux cas, le ton de sa voix, car les hautes fr\u00e9quences sont plus efficaces contre le bruit de fond que les basses fr\u00e9quences.<\/p>

En l’absence de mesures d’acoustique des salles, ces niveaux de bruit toujours croissants entra\u00eenent une fatigue et un manque de motivation des personnes concern\u00e9es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
