本标准的目的是规定一种方法，用于评估特定听力条件下耳科正常成年人感知的固定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。

The objective of this Standard is to specify 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.
