Acoustics - Hearing protectors - Part 2 : estimation of effective A-weighted sound pressure levels when hearing protectors are worn

Le présent document décrit trois méthodes : la méthode par bande d'octave, la méthode HML et la méthode SNR pour estimer les niveaux de pression acoustique effectifs pondérés A en cas d'utilisation de protecteurs individuels contre le bruit. Ces méthodes s'appliquent soit au niveau de pression acoustique, soit au niveau de pression acoustique continu équivalent du bruit. Elles s'appliquent également à des bruits comportant des composantes impulsives mais ne conviennent pas aux mesurages du niveau de pression acoustique de crête.

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.
