The existing body of literature regarding the acoustic design of concert halls has focused almost exclusively on classical music, although there are many more performances of popular music, including rock and pop. Objective measurements were made of the acoustics of 20 rock music venues in Denmark and a questionnaire was used in a subjective assessment of those venues with professional rock musicians and sound engineers as expert listeners. Correlations between the measurements show that clarity, including bass frequencies down to 63 Hz, is important for the general impression of the acoustics of the hall. The best-rated halls in the study have reverberation times that are approximately frequency independent from 0.6 to 1.2 s for hall volumes from 1000 to 6000 m(3). The worst rated halls in the study had significantly higher reverberation times in the 63 and 125 Hz bands. Since most audiences at rock concerts are standing, absorption coefficients were measured with a standing audience from 63 Hz to 4 kHz. These measurements showed that a standing audience absorbs about five times as much energy in mid-/high-frequency bands as in low-frequency bands.
关于音乐厅声学设计的现有文献几乎完全集中在古典音乐上，尽管有更多的流行音乐表演，包括摇滚和流行音乐。对丹麦 20 个摇滚音乐场所的声学进行了客观测量，并使用问卷对这些场所进行了主观评估，由专业摇滚音乐家和音响工程师作为专家听众进行评估。测量结果之间的相关性表明，清晰度，包括 63 Hz 以下的低音频率，对大厅声学的总体印象很重要。在这项研究中评价最高的音乐厅的混响时间在 0.6 到 1.2 秒之间，几乎与频率无关，其大厅容积在 1000 到 6000 立方米之间。在这项研究中评价最差的音乐厅在 63 和 125 Hz 频段的混响时间明显更高。由于摇滚音乐会上的大多数观众都是站着的，因此从 63 Hz 到 4 kHz 对站着的观众进行了吸声系数测量。这些测量表明，站着的观众在中/高频带吸收的能量大约是低频带的五倍。
