标准范围

ISO 532-2:2017规定了一种方法，用于评估特定听力条件下耳科正常成年人感知的静止声音的响度和响度水平。它提供了一种算法，用于计算使用单个麦克风、使用头部和躯干模拟器记录的声音，或通过耳机呈现的声音的单耳或双耳响度。该方法基于摩尔-格拉斯伯格算法。注1:附录A讨论了双耳计算问题。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，源代码完全是信息性的，并随ISO 532-2:2017提供，以方便用户。该方法适用于音调、宽带噪声和具有尖锐线谱成分的复杂声音，例如变压器嗡嗡声或风扇噪声。注3:已证明（见参考文献[15]）该方法与ISO 226中定义的等响度水平轮廓具有良好的匹配性:以及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ISO 532-2:2017的范围内。

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 ISO 532-2:2017 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 ISO 532-2:2017.
