Acoustics - Noise emitted by machinery and equipment - Guidelines for the use of basic standards for the determination of emission sound pressure levels at a work station and other specified positions (ISO 11200:1995)
The International Standard provides brief summaries of the basic International Standards for determining emission sound pressure levels from all types of machinery and equipment, at work stations and at other specified positions, and gives guidelines on the process of selection of which is appropriate to any particular type. The guidance given applies only to airborne sound, and is for use in the preparation of noise test codes, and also for use in noise testing where no code exists. It is important that specific noise test codes for various types of machinery and equipment be established and used in accordance with the requirements of these basic International Standards. Such standardized noise test codes will give detailed requirements on mounting and operating conditions for the particular family to which the machine under test belongs, as well as the location of the work station(s) and other specified positions as prescribed in these International Standards. The data so obtained may also be used for the declaration and verification of emission sound pressure levels as specified in ISO 4871. Note: At any given position in relation to a particular machine, and for given mounting and operating conditions, the emission sound pressure levels determined by any of the methods given in ISO 11201 to ISO 11204 will in general be lower than the directly measured sound pressure levels for the same machine in the typical workroom where it is used. This is due to reverberation and the contributions of other machines. A method of calculating the sound pressure levels in the vicinity of a machine operating alone in a workroom is given in ISO 11690-3. Commonly observed differences are 1 dB to 5 dB, but in extreme cases the difference may be even greater.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation 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
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated 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 11200 was prepared by Technical Committee
ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.
Annex A forms an integral part of this Inter national Standard. Annex B is
for information only.

Introduction
0.1 Control of noise from machinery or equipment requires effective
exchange of acoustical information among the several parties concerned.
These include the manufacturer, installer and user of the machinery or
equipment. This acoustical information is obtained from measurements.
These measurements are useful only if the conditions under which they
are carried out are specified, if they yield defined acoustical quantities, and
if they are made using standardized instruments.
Two quantities which complement one another can be used to describe
the sound emission of machinery or equipment. One of them is the sound
power level and the other is the emission sound pressure level at a
specified position. The International Standards which describe the basic
methods of determining the sound power level are IS0 3740 to IS0 3747
and IS0 9614-I and IS0 9614-2. This International Standard introduces a
series of four International Standards describing various methods for de-
termining emission sound pressure levels of machinery and equipment.
Emission sound pressure levels are sound pressure levels at one or more
positions located in the vicinity of an item of machinery or equipment,
which arise solely from the noise emitted by that machinery or equipment
when it performs a specified function under given operating conditions,
on a particular mounting in a defined acoustic environment. The operating
and mounting conditions are the same as those used in the determination
of sound power levels. The positions with which this series of International
Standards is concerned include work stations, normally specified in a noise
test code (if one exists), occupied by one or more operators of the ma-
chinery, and other positions which may be occupied from time to time by
other persons. The positions may be located in the vicinity of the ma-
chinery, or in a cab, or in some other enclosure more or less remote from
the machinery. Emission sound pressure levels may arise from contin-
uous, steady operational machinery or they may be averages for a defined
work cycle; they are not averages over a total working day during which
the machinery might perform different functions, operate at different
control settings, or undergo changes of work load.
Emission sound pressure levels in conjunction with sound power levels
are used for declaration of the noise emitted under the defined conditions,
verification of declared values, comparison of the noise emitted by ma-
chinery of various types and sizes, comparison with limits specified in a
purchasing contract or a regulation, engineering work to reduce the noise
emission of machinery, and prediction of noise exposure at the specified
positions.
For many products, the sound power level is the primary metric for com-
parison of noise emissions. Noise test codes and specific declaration
codes should state the primary metric for comparison.

It is not the intent of this series of International Standards to describe
procedures for measuring the occupational noise exposure of workers.
Included in this series of International Standards are three which describe
procedures for measuring emission sound pressure levels directly, in dif-
ferent test environments (IS0 11201, IS0 11202 and IS0 11204), and a
fourth (IS0 11203) which gives procedures for determining emission
sound pressure levels from the sound power level. When applying these
standards to sound measurements on specific machinery, it is necessary
to decide which is the most appropriate for the particular type of machin-
ery or equipment and for the purpose of the test. Guidelines for making
this decision are provided in this International Standard.
0.2 The series of International Standards for which this International
Standard serves as the introduction comprises IS0 11201, IS0 11202,
IS0 11203 and IS0 11204. In principle, the methods of determining
emission sound pressure levels described in IS0 11201 to IS0 11204
cover all types of machinery and equipment. For noise measurements on
a particular kind and size of machinery or equipment, or when there are
certain practical limitations, only one of these International Standards may
be applicable.
IS0 11201 to IS0 II 204 make up a set of basic International Standards
which specify the acoustical conditions and instrumentation to be used,
describe the procedures to be followed, and give general information on
the installation and operation of the machine under test, when determining
emission sound pressure levels. In general, these sound pressure levels
are different from those that would occur if the machinery or equipment
were operating in its normal surroundings, where the environment may
influence the emission sound pressure level. The selection of standards
for the determination of the sound power level can, for practical reasons,
have consequences on the selection of standards for the determination
of the emission sound pressure level. It is preferable to make the choice
of standards concurrently with respect to the two noise emission quan-
tities.
0.3 This International Standard is one of a series which specifies various
methods for determining the noise emissions of a piece of machinery or
equipment, or a sub-assembly of such equipment (machine under test).
Standards in this series are grouped in three categories, as follows.
a) Methods for the determination of emission sound pressure levels
at work stations and at other specified positions
In addition to this International Standard, this category includes the
following standards (see table 1):
- IS0 11201 gives an engineering method for measuring emission
sound pressure levels of machinery and equipment, in an essen-
tially free field over a reflecting plane, with no environmental cor-
rection;
- IS0 11202 gives a survey method for measuring emission sound
pressure levels of machinery and equipment in situ with an en-
vironmental correction using a simplified method;
---------------------- Page: 12 ----------------------

- IS0 11203 gives two alternative methods for determining the
emission sound pressure levels of machinery and equipment from
the sound power levels;
- IS0 11204 gives a method for measuring the emission sound
pressure levels of machinery and equipment yielding engineering
grade or survey grade results.

b)
- IS0 3740 gives guidelines for the choice of the method to be used
for determining the sound power emitted by machinery and
equipment;
- IS0 3741 to IS0 3747 give methods for determining the sound
power levels of machinery and equipment via sound pressure
measurements;
- parts 1 and 2 of IS0 9614 describe methods for determining the
sound power levels of machinery and equipment via sound inten-
sity measurements.
c) Noise tests codes
For a particular family of machinery or equipment, noise test codes
specify:
- the meth od to be used for the determination of the sound p ower
- the method to be used for the determination of emission sound
pressure levels at work stations, and at other specified positions;
- the positions of the work stations;
- the mounting and operating conditions of the machine under test
for the purpose of determining the noise emission quantities;
- the method to be used for verifying declared noise emission
quantities.
