Acoustics - Recommended practice for the design of low-noise workplaces containing machinery - Part 1: Noise control strategies (ISO 11690-1:2020)

This document outlines strategies to be used in dealing with noise problems in existing and planned workplaces by describing basic concepts in noise control (noise reduction, noise emission, noise immission and noise exposure). It is applicable to all types of workplaces and all types of sources of sound which are met in workplaces, including human activities.
It includes those important strategies to adopt when buying a new machine or equipment.
This document deals only with audible sound.

Ausgehend von der Beschreibung der grundlegenden Konzepte des Schallschutzes (Lärmminderung, Geräuschemission, Geräuschimmission und Geräuschexposition), beschreibt dieses Dokument Strategien für die Behandlung von Lärmproblemen in bestehenden und geplanten Arbeitsstätten. Es ist anwendbar auf alle Arten von Arbeitsstätten und alle Arten von Schall, die in Arbeitsräumen vorkommen können, wobei auch menschliche Tätigkeiten eingeschlossen sind.
Sie enthält wichtige Hinweise, die beim Kauf einer neuen Maschine oder Anlage anzuwenden sind.
Dieses Dokument befasst sich ausschließlich mit Hörschall.

Acoustique - Pratique recommandée pour la conception de lieux de travail à bruit réduit contenant des machines - Partie 1: Stratégies de maîtrise du bruit (ISO 11690-1:2020)

Le présent document présente les stratégies à mettre en œuvre pour traiter les problèmes de bruit sur les lieux de travail existants ou en projet, en s'appuyant sur des concepts de base liés à la maîtrise du bruit (maîtrise du bruit, émission sonore, bruit ambiant et exposition au bruit). Il s'applique à tous les types de lieux de travail et de sources de bruit rencontrées sur les lieux de travail, activités humaines comprises.
Il inclut les stratégies importantes à adopter lors de l'achat d'une nouvelle machine ou d'un nouvel équipement.
Le présent document ne traite que des sons audibles.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
