Acoustics. Determination of sound power levels of noise sources using sound pressure. Engineering methods for small, mowable sources in reverberant fields. Part 2 : methods for special reverberation test rooms.

Le présent document prescrit une méthode d''expertise relativement simple pour la détermination des niveaux de puissance acoustique de sources de bruit transportables de petites dimensions. Les mesurages sont effectués quand la source est installée dans une salle conçue spécialement, ayant une durée de réverbération donnée, dans le domaine de fréquences représentatif. Le niveau de puissance acoustique pondéré A de la source en essai est déterminé à partir d''une seule mesure de la pression acoustique pondérée A pour chaque position de microphone, au lieu d''effectuer une somme sur l''ensemble des niveaux par bande d''octave (méthode directe). Une méthode par comparaison est également décrite. Cependant, si une salle d''essai réverbérante spéciale n''est pas disponible, il est recommandé d''utiliser la méthode par comparaison de l''ISO 3743-1 car les spécifications de la salle d''essai exigées dans cette partie 1 sont bien moins contraignantes.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
