    25、 edition 1987-04-15 Reference number ISO 1996-2: 1987 (E) 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 committe

    26、es. Esch 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopte

    27、d by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 1996-2 wa

Part 2 : Acquisition of data pertinent to land use. Part 3 : Application to noise Iimits. 0.2 This part of ISO 1996 descr

    31、ibes methods to be used for measuring and describing environmental noise relevant to general land use. The use of different measuring methods, such as continuous integration, sampling techniques and measurements under selected meteorological coriditions, is considered. Calculation methods or scale m

    32、odel investigations may also be used. This part of ISO 1996 does not deal in detail with calculation methods. If, however, such methods are used to obtain data pertinent to land use, it is important that the noise be described in a way that is consistent with the requirements of this part of ISO 199

    33、6. The purpose of this part of ISO 1996 is to provide methods for the acquisition of data for describing environmental noise. Using these data as a basis, authorities may establish a System for selecting the appropriate land use, as far as levels of noise are concerned, for a specified area, or the

    34、sources of noise - existing or planned 7 which are acceptable with respect to land use, existing or planned. This part of ISO 1996 does not give guidance on the estimation of the Overall uncertainty of the results, but this shoutd be considered in each specific case, if possible. lt does not specify

    35、 noise limits. 1 Scope and field of application This part of ISO 1996 describes methods for the acquisition of data which provide descriptors that enable a) a description of the environmental noise in a specified area of land to be made in a uniform way; b) the compatibility of any land use activity

    36、 or projected activity to be assessed with respect to.existing or predicted noise. 2 References ISO 1996-1, Acoustics - Description and measurement of environmental noise - Part 7 : Basic quantities and procedures. 1 ) IEC Publication 651, Sound level meters.

    38、el lies between two specified levels such as, for example, between 65 and 70 d. The noise zone number for this example is 65-70 dB. 3.3 receiver : Person or group of persons who are or who are expected to be exposed to environmentat noise. 4 Acquisition of data . For the purpose of acquisition of da

    39、ta relevant to land use, the following basic information is required : a) geographicat description of the area under consider- ation; 1) Cross-references to specific clauses, sub-clauses, etc. in ISO 1996-1 apply to the first edition published in 1982.

    40、 characteristics of the sources of noise pertinent to this area; 6 dB. If the components are only just detectable by the observer and demonstrated by narrow-band analysis, an adjustment of 2 to 3 dB may be appropriate. c) description of the Situation of the receiver, such as location, occupation, us

    41、e and features of the immediate surroundings. 4.1.4 Impulse adjustment, KZ If impulse is an essential characteristic of the Sound within a specified time intervat, an adjustment may be applied, for this time interval, to the measured equivalent continuous A-weighted Sound pressure level. The value o

    42、f this adjustment shall be stated. NOTE - If possible, information on prevailing meteorological conditions in the area under consideration should be given, preferably as statistical information on wind Speed and direction, on precipitation and temperature (including the occurrence of temperature inv

    43、ersions) for a typical time interval, such as a year or any other suitable time interval. NOTES 1 A method of describing the impulse characteristic of the Sound within the specified time interval is to measure the differente between the A-weighted Sound pressure level, determined with time-weightinq

    44、 characteristic I averaged over the same time interval, and LAeq r The Sound pressure levels should be determined simultaneousl;. The Character of the noise may be further illustrated by determining the peak level and the number of impulses during a specified time interval. 4.1 Acoustical data 4.1.1

    45、 General Basic acoustical data are equivalent continuous A-weighted Sound pressure levels determined over the reference time intervals and rating levels for the same reference time intervals with additional information on the characteristics of the noise, if required. 2 For large-amplitude noise, su

    46、ch as the noise generated by sonic booms, mining or quarry blasts, measurements with C-weighting are used in some countries to determine the rating level. 4.1.2 Rating level 4.2 Meteorological adjustment The rating level shall be determined over reference time intervals related to the characteristic

    47、s of the source(s) and receiverk). To extrapolate from a value of the equivalent continuous A-weighted Sound pressure levei measured under selected meteorological conditions to a long-term value, a meteoro- logical adjustment may be used (sec 5.3 in ISO 1996-1).
