BS ISO 532-2:2017规定了估算固定声音响度和响度水平的方法 在特定的听力条件下，耳科正常的成年人会感觉到。它提供了一个 计算单声道或双耳声音响度的算法 麦克风，使用头部和躯干模拟器，或通过耳机呈现声音。方法是 基于摩尔-格拉斯伯格算法。注1:附录A讨论了双耳计算的问题。注2:希望研究计算方法细节的用户可以查看或实施源代码 代码，该代码完全是信息性的，为方便用户，随本文档一起提供。该方法适用于声调、宽带噪声和具有尖锐线谱的复杂声音 组件，例如变压器嗡嗡声或风扇噪音。 注3:已证明（见参考文献[15]）该方法能很好地匹配等高线 ISO 226:2003中定义的响度水平和ISO 389-7:2005中定义的参考听力阈值。声音事件有害影响的评估不在本文件范围内。交叉引用:IEC 61260-1:2014ISO 80000-8:2007 Ed 1IEC TS 60318-7:2011IEC 61672-1:2013 ISO 3740:2000 Ed 2ISO 9612:2009 Ed 2IEC 60050-702:1992/AMD2:2016ISO 532:1975ISO/IEC指南98-3:2008 Ed 1ISO 389-7:2005ISO 11200:2014 Ed 2ISO 11904-1:2002 Ed 1（R08）ISO 1996-1:2016ISO 226:2003 Ed 2购买本文件时提供的所有现行修订版均包含在本文件中。

BS ISO 532-2:2017 specifies a method for estimating the loudness and loudness level of stationary sounds as perceived by otologically normal adult persons under specific listening conditions. It provides an algorithm for the calculation of monaural or binaural loudness for sounds recorded using a single microphone, using a head and torso simulator, or for sounds presented via earphones. The method is based on the Moore-Glasberg algorithm.NOTE 1 Issues of binaural calculations are discussed in Annex A.NOTE 2 Users who wish to study the details of the calculation method can review or implement the source code, which is entirely informative and provided with this document for the convenience of the user.This method can be applied to tones, broadband noises and complex sounds with sharp line spectral components, for example transformer hum or fan noise.NOTE 3 It has been shown (see Reference [15]) that this method provides a good match to the contours of equal loudness level as defined in ISO 226:2003 and the reference threshold of hearing as defined in ISO 389-7:2005.The evaluation of the harmful effect of sound events is outside the scope of this document.Cross References:IEC 61260-1:2014ISO 80000-8:2007 Ed 1IEC TS 60318-7:2011IEC 61672-1:2013 ISO 3740:2000 Ed 2ISO 9612:2009 Ed 2IEC 60050-702:1992/AMD2:2016ISO 532:1975ISO/IEC GUIDE 98-3:2008 Ed 1ISO 389-7:2005ISO 11200:2014 ED2ISO 11904-1:2002 Ed 1 (R08)ISO 1996-1:2016ISO 226:2003 Ed 2All current amendments available at time of purchase are included with the purchase of this document.
