Acoustics - Noise emitted by machinery and equipment - Determination of emission sound pressure levels at a work station and at other specified positions from the sound power level (ISO 11203:1995)

This standard specifies methods for determining the emission sound pressure levels at the work station and at other specified positions in the vicinity of machinery and equipment from the sound power level. In general, these sound pressure levels are different from those that would be observed when the machinery or equipment is operating in its normal surroundings where the environment may influence the emission sound pressure level. This standard prescribes two methods for determining the emission sound pressure levels of machinery and equipment, at work stations and at other specified positions nearby, by calculation from the sound power level. The principal purpose of this determination is to permit comparison of the performance of different units of a given family of machinery or equipment, under defined environmental conditions and standardized mounting and operating conditions. This Standard is in principle applicable to moving or stationary machines, for indoor or outdoor use, particularly those machines which are mass-produced. The methods given in this Standard are not applicable to highly directional sound sources used outdoors.

IS0 11203:1995(E) 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 11203 was prepared by Technical Committee lSO/TC 43, Acoustics, Subcommittee SC 1, Noise.

CJ IS0 IS0 11203:1995(E) Introduction 0.1 This International Standard specifies methods for determining the emission sound pressure levels at a work station and at other specified positions in the vicinity of machinery and equipment from the sound power level. In general, these sound pressure levels are different from those that would be observed when the machinery or equipment is oper- ating in its normal surroundings where the environment may influence the emission sound pressure level. 0.2 This International Standard is one of a series (IS0 11200 to IS0 11204) 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). IS0 11200 gives guidance on the choice of the method to be used to determine the emission sound pressure levels of machinery and equipment. It also gives details of International Standards giving methods for the de- termination of sound power levels. SIST EN ISO 11203:2009

INTERNATIONAL STANDARD 0 ISO IS0 11203:1995(E) Acoustics - Noise emitted by machinery and equipment - Determination of emission sound pressure levels at a work station and at other specified positions from the sound power level 1 Scope 1 .I General This International Standard specifies two methods for determining the emission sound pressure levels of machinery and equipment, at a work station and at other specified positions nearby, by calculation from the sound power level. The principal purpose of this determination is to permit comparison of the per- formance of different units of a given family of ma- chinery or equipment, under defined environmental conditions and standardized mounting and operating conditions. The data obtained may also be used for the declaration and verification of emission sound pressure levels as specified in IS0 4871. Emission sound pressure levels are determined with the same frequency weighting and time weighting, or in the same frequency bands, as those for which sound power levels have been determined. NOTES I The contents of this and related International Standards are summarized in table 1 of IS0 11200:1995. 2 At any given position in relation to a particular machine, and for given mounting and operating conditions, the emis- sion sound pressure levels determined by the method of this International Standard will in general be lower than the directly measured sound pressure levels for the same ma- chine 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 IS0 11690-3. Commonly observed differences are I dB to 5 dB, but in extreme cases the difference may be even greater. 1.2 Types of noise and noise sources This International Standard is, in principle, applicable to moving or stationary machines, for indoor or out- door use, particularly those machines which are mass-produced. The methods given in this Inter- national Standard are not applicable to highly direc- tional sound sources used outdoors. This International Standard is particularly applicable to machines whose largest dimension is less than or equal to 1 m. It is also applicable to larger machines in certain cases (see 6.2.3). This International Standard is applicable to all types of noise as defined in IS0 2204 and IS0 12001 for which methods for determining the sound power level are available. 1.3 Test environment The test environment to be used is that which is specified for the determination of the sound power level in accordance with the International Standards of the IS0 3740 or IS0 9614 series. 1.4 Specified positions This International Standard is applicable to work stations and other specified positions in the vicinity of the source under test where emission sound pressure levels are to be determined. It is not appli- cable to work stations and other defined positions which are situated inside a cab or a cabin, or behind a screen. SIST EN ISO 11203:2009



IS0 11203:1995(E) 0 IS0 A work station can be a single point, corresponding to the specified position of a standing or seated op- erator. It can also be a specified path. NOTE 3 More detailed specifications regarding seated, standing, stationary or moving operators, as well as infor- mation concerning bystanders, are to be found in IS0 ll201. 1.5 Specific field of application of each method Specific information on the field of application of each of the two methods described in this International Standard is given in 6.2.2 and 6.2.3. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
