Le niveau de pression acoustique Lp est une mesure logarithmique du rapport entre un événement sonore d'amplitude p et le seuil d'audibilité p0, qui est exprimée en décibels (dB): Lp = 20 log (p/p0). Les sons audibles par l'homme s'étendent ainsi de 0 à 120 dB. 6, record 1, French, - niveau%20de%20pression%20acoustique
Record number: 1, Textual support number: 2 CONT
le niveau de pression acoustique est égal à 20 fois le logarithme décimal du rapport entre la pression P due à une onde et la pression de référence. 7, record 1, French, - niveau%20de%20pression%20acoustique
