La présente Norme internationale s'applique à tous les types d'environnements d'essai autres que celui rencontré en laboratoire, à condition que le niveau de bruit de fond soit suffisamment faible et que le niveau de pression acoustique aux différentes positions de microphone dépende principalement des réflexions par les surfaces de la salle. NOTE L'ISO 3744 ou l'ISO 9614 peut fournir des méthodes alternatives. La présente Norme internationale s'applique principalement aux sources qui émettent un bruit à large bande. Cependant, elle peut également s'appliquer aux sources qui émettent un bruit à bande étroite ou des sons purs, bien que l'incertitude de mesure puisse alors devenir plus importante que celle indiquée ici. NOTE L'ISO 9614 peut être utilisée comme norme alternative pour les sources de bruit qui émettent un bruit stable.
