Les mesures en laboratoire de la perte de transmission de son sont effectuées par bandes de tiers d’octave de 125 à 4 000 Hz. Cependant, il est commode de comparer les ensembles de construction à l'aide d’un seul nombre. La désignation la plus couramment utilisée en Amérique du Nord est l'indice de transmission du son(ITS). Cet indice est obtenu en comparant la courbe des pertes de transmission mesurée d’un ensemble à des courbes ITS de référence. Seule une partie limitée de la courbe des pertes de transmission est autorisée à descendre au-dessous de la courbe des indices de transmission du son. Plus l'ITS est élevé, meilleures sont les caractéristiques acoustiques de la cloison. 4, record 4, French, - indice%20de%20transmission%20du%20son

Il arrive que l'analyse par octave ne donne pas de résultats suffisamment précis, étant donné que chaque octave est affectée d’un seul chiffre correspondant au niveau de pression acoustique global dans l'octave. [...] Aussi on utilise [...] la possibilité de faire une analyse plus fine par bandes de tiers d’octave. Cela revient à découper l'intervalle d’octave en trois parties égales sur l'échelle logarithmique des fréquences. 3, record 12, French, - bande%20de%20fr%C3%A9quences%20de%20tiers%20d%27octave

Un analyseur de spectre dans votre PC [...] La calibration en fréquence du signal à partir d’un fichier configurable permet un étalonnage précis de l’acquisition. La génération de signaux (bruit blanc, rose, dent de scie, carré, impulsion de Dirac, sinusoïdal, etc.), les pondérations usuelles (A, B, C, Lin) et la recomposition par bandes de 1/3 d’octave font de cet outil un précieux auxiliaire pour les mesures acoustiques en complément d’un sonomètre. 2, record 12, French, - bande%20de%20fr%C3%A9quences%20de%20tiers%20d%27octave
