This test method determines sound power by a comparison method for small noise sources, that is, comparison to a broadband reference sound source.1.3This test method describes a procedure for determining the approximate A-weighted sound power level of small noise sources. This test method uses a non-special semi-reverberant room.1.4Results are expressed as A-weighted sound power level in decibels (referenced to one picowatt).1.5The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.Note 1:The F11.21 subcommittee is actively pursuing new market relevant carpets with the assistance of the carpet industry. Although plush and Freize carpet panels are no longer available for purchase, some laboratories may still have samples for testing. In such cases, the table values remain valid.1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ======4.1The test results enable the comparison of A-weighted sound emission from vacuum cleaners, backpack vacuum cleaners, extractors, or hard-floor cleaning machines when tested under the condition of this test method. -

实施时间:摘要: This document specifies an engineering method for calculating the attenuation of sound during propagation outdoors in order to predict the levels of environmental noise at a distance from a variety of sources. The method predicts the equivalent continuous A-weighted sound pressure level (as described in ISO?1996-series) under meteorological conditions favourable to propagation from sources of known sound emission.These conditions are for downwind propagation or, equivalently, propagation under a well-developed moderate ground?based temperature inversion, such as commonly occurs in clear, calm nights. Inversion conditions over extended water surfaces are not covered and may result in higher sound pressure levels than predicted from this document (see e.g. References [11] and [12]).The method also predicts a long-term average A?weighted sound pressure level as specified in ISO?1996-1 and ISO?1996-2. The long-term average A?weighted sound pressure level encompasses levels for a wide variety of meteorological conditions.Guidance has been provided to derive a meteorological correction based on the angular wind distribution relevant for the reference or long-term time interval as specified in ISO?1996-1:2016, 3.2.1 and 3.2.2. Examples for reference time intervals are day, night, or the hour of the night with the largest value of the sound pressure level. Long-term time intervals over which the sound of a series of reference time intervals is averaged or assessed representing a significant fraction of a year (e.g. 3?months, 6?months or 1?year).The method specified in this document consists specifically of octave band algorithms (with nominal mid-band frequencies from 63?Hz to 8?kHz) for calculating the attenuation of sound which originates from a point sound source, or an assembly of point sources. The source (or sources) may be moving or stationary. Specific terms are provided in the algorithms for the following physical effects:—?geometrical divergence;—?atmospheric absorption;—?ground effect;—?reflection from surfaces;—?screening by obstacles.Additional information concerning propagation through foliage, industrial sites and housing is given in Annex?A. The directivity of chimney-stacks to support the sound predictions for industrial sites has been included with Annex?B. An example how the far-distance meteorological correction?C0 can be determined from the local wind-climatology is given in Annex?C. Experiences of the last decades how to predict the sound pressure levels caused by wind turbines is summarized in Annex?D.The method is applicable in practice to a great variety of noise sources and environments. It is applicable, directly, or indirectly, to most situations concerning road or rail traffic, industrial noise sources, construction activities, and many other ground-based noise sources. It does not apply to sound from aircraft in flight, or to blast waves from mining, military, or similar operations.To apply the method of this document, several parameters need to be known with respect to the geometry of the source and of the environment, the ground surface characteristics, and the source strength in terms of octave band sound power levels for directions relevant to the propagation.If only A?weighted sound power levels of the sources are known, the attenuation terms for 500?Hz may be used to estimate the resulting attenuation.The accuracy of the method and the limitations to its use in practice are described in Clause?9. -

实施时间:摘要: This document specifies methods for measuring the airborne noise emitted by small air-moving devices (AMDs), such as those used for cooling electronic, electrical, and mechanical equipment where the sound power level of the AMD is of interest.Examples of these AMDs include propeller fans, tube-axial fans, vane-axial fans, centrifugal fans, motorized impellers, and their variations.This document describes the test apparatus and methods for determining the airborne noise emitted by small AMDs as a function of the volume flow rate and the fan static pressure developed by the AMD on the test apparatus. It is intended for use by AMD manufacturers, by manufacturers who use AMDs for cooling electronic equipment and similar applications, and by testing laboratories. It provides a method for AMD manufacturers, equipment manufacturers and testing laboratories to obtain comparable results. Results of measurements made in accordance with this document are expected to be used for engineering information and performance verification, and the methods can be cited in purchase specifications and contracts between buyers and sellers. The ultimate purpose of the measurements is to provide data to assist the designers of electronic, electrical or mechanical equipment which contains one or more AMDs.Based on experimental data, a method is given for calculating the maximum volume flow rate of the scaled plenum up to which this document is applicable. -

摘要: 本文件提供了按 IEC 61672-3进行声级计的周期试验所要求的在某一频率范围内的修正值的相关信息,这些修正值包括:
——来自声级计壳体的反射和传声器周围声衍射的典型影响的修正值;
——不能测量实际的传声器响应时,典型的传声器频率响应与均匀频率响应之偏差的修正值;
——作为交付试验的特定声级计的标称使用配置一部分而规定的风罩或任何其他附件,对传声器典型频率响应影响的修正值。
本文件包括了对所要求的修正值的测量不确定度的讨论,在有些实例中,为制造者或测试实验室给出了最大允许扩展测量不确定度。这些最大允许扩展不确定度不包括任何由于人工制品(例如传声器或风罩)的不同样本的差异而带来的分量。宜注意,如果每个修正值都引入较大的测量不确定度,当考虑被试声级计的配置而合成时,这些大的个体的不确定度可导致不符合GB/T 3785.1—2023中表A.1给出的最大允许扩展测量不确定度,从而使声级计不符合GB/T 3785.1。
此外,本文件描述了在感兴趣的频率范围内确定这些修正值的方法,并解释了由声级计制造者提供的(也是IEC 61672-3所要求的)校准检查频率上的调整值。
当声级计制造者为声级计在不同频率上的声响应的周期试验而推荐使用声校准器、比较耦合器或静电激励器时,本文件描述了为在所有感兴趣的频率范围内,将声级计的指示调整到等效的自由场级所要求的修正值的测量方法。这些修正值与规定型号的声校准器、比较耦合器或静电激励器以及传声器和声级计相关(IEC 61672-3也要求)。
本文件的目的是确保校准检查频率上的调整值和所有的修正值都是采用一致且适当的方法所确定的。
本文件有意提供给制造者在测量调整值和修正值时,实验室按照IEC 61672-2进行型式评价试验,以及实验室按照IEC 61672-3进行周期试验时使用。获取标准 -
