La présente partie de l'ISO 11690 présente les stratégies à mettre en oeuvre 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 réduction du bruit (réduction du bruit, émission sonore, bruit ambiant et exposition sonore). Elle s'applique à tous les types de lieux de travail et de sources de bruit rencontrées sur les lieux de travail, activités humaines comprises. Elle inclut les stratégies importantes à adopter à l'achat d'une nouvelle machine ou d'un nouvel équipement. La présente partie de l'ISO 11690 ne traite que des sons audibles.

Foreword
IS0 (the International Organization for Standardization) is a worldwide fed-
eration of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0 collabo-
rates closely with the International Electrotechnical Commission (IEC) on
all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 11690-I was prepared by Technical Committee
lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.
IS0 11690 consists of the following parts, under the general title Acous-
tics - Recommended practice for the design of low-noise workplaces
containing machinery:
- Part I: Noise control strategies
- Par? 2: Noise control measures
Part 3: Sound propagation and noise prediction in workrooms
Part 1 is the central document in the series. Parts 2 and 3 give additional
technical and explanatory information. It is therefore recommended to start
with part I.
Annex A of this part of IS0 11690 is for information only.

trod uction
Most of the existing International Standards prepared in ISO/TC 43/SC 1
specify methods for measurement and/or evaluation of noise. The final
objective of IS0 11690, however, is noise reduction.
A number of noise control measures are offered. However, in order to be
effective, the most appropriate noise control measure(s) should be chosen
for a given situation.
It is important when non-acoustic engineers are involved in noise control
practice for these engineers to have a basic knowledge of noise emission
and propagation characteristics and to understand the basic principles of
noise control.
To assist in the development of noise control in the workplace, it is essen-
tial that the information contained in these recommended practices is dis-
seminated through International Standards.
In order to reduce noise as a hazard in the workplace, individual countries
have produced national legislation. Generally, such national legislation
requires noise control measures to be carried out in order to achieve the
lowest reasonable levels of noise emission, noise immission and noise ex-
posure, taking into account:
- known available measures;
- the state of the art regarding technical progress;
the treatment of noise at source;
-
- appropriate planning, procurement and installation of machines and
equipment.
This part of IS0 11690, together with the two other parts in the series, out-
lines procedures to be considered when dealing with noise control at
workplaces, within workrooms and in the open. These recommended prac-
tices give in relatively simple terms the basic information necessary for all
parties involved in noise control in workplaces and in the design of low-
noise workplaces to promote the understanding of the desired noise control
requirements.
The purpose of the IS0 11690 series is to bridge the gap between existing
literature on noise control and the practical implementation of noise control
measures. In principle, the series applies to all workplaces and its main
function is:
- to provide simple, brief information on some aspects of noise control
in workplaces;
- to act as a guide to help in the understanding of requirements in stan-
dards, directives, text books, manuals, reports and other specialized
technical documents;
@ IS0 IS0116904:1996(E)
- to provide assistance in decision making when assessing the various
measures available.
The IS0 11690 series should be useful to persons such as plant person-
nel, health and safety officers, engineers, managers, staff in planning and
purchasing departments, architects and suppliers of plants, machines and
equipment. However, the above-mentioned parties should keep in mind
that adherence to the recommendations of the IS0 11690 series is not all
that is necessary to create a safe workplace.
The effects of noise on health, well-being and human activity are many. By
giving guidelines for noise control strategies and measures, the IS0 11690
series aims at a reduction of the impact of noise on human beings at
workplaces. Assessment of the impact of noise on human beings is dealt
with in other documents.
