厅堂音质评价的各项指标中，响度是最重要和最基本的内容之一。但由于长期来缺乏合适的参量，因此迄今无法在完工后的厅堂中去测量这项指标，当然也难以在设计阶段对此参量进行估算．不少人常把仅仅适用于稳态声源和混响场的声场估算法（即以直达声加上混响声）作为厅堂内各处总声强的评价，无论从音质设计和现场测量来看，显然很不合适。近年Ｌｅｈｍａｎｎ提出以声强指数Ｇ（Ｓｔａｒｋｅｍａｓｓ）（ｄＢ）作为评价参量是一个好的建议。但根据我们的研究结果来看，鉴于早期反射声对响度起主导作用，因此厅堂内各处的声强指数应取５０ｍｓ（语言）和８０ｍｓ（音乐）的早期反射声积分值更符合实际，。以代替ｔ从０积分到∞的评价方法。因此Ｇ（５０ｍｓ）和Ｇ（８０ｍｓ）将分别用于评价厅堂内对语言和音乐的响度评价参量。
Loudness is one of the most important and basic elements in the evaluation of hall sound quality. However, due to the lack of suitable parameters for a long period of time, it has not been possible to measure this indicator in the completed hall. It is, of course, difficult to estimate this parameter during the design phase. Many people often use sound field estimation methods that are only applicable to steady-state sound sources and reverberation fields (that is, direct sound plus reverberation sound) as the evaluation of the total sound intensity in the halls, regardless of sound quality design and on-site measurement. , obviously not very suitable. In recent years, Lehmann proposed a sound strength index (Starkemass) (dB) as an evaluation parameter. However, according to our research results, given that the early reflection sound plays a dominant role in loudness, the sound intensity index in each part of the hall should take the early reflection integration value of 50ms (language) and 80ms (music) as being more realistic. Instead of t from 0 to ∞ evaluation method. Therefore, G(50ms) and G(80ms) will be used to evaluate the loudness evaluation parameters for language and music in the hall.
