The challenge in the acoustics design of the traditional mosque is twofold. First, the interior atmosphere of the space should create a sacred feeling on the users' holistic and phenomenological spatial perception, which is generally recognized as a direct effect of increased reverberation time (T30) and low clarity (C80). Second, speech should be adequately intelligible, which requires a low T30 and high speech clarity, contradicting the initial concern of the sacred atmosphere. We hypothesize that in Islamic architecture, wooden hypostyle mosques may comply better with the reverberation time requirements of speech intelligibility, while maintaining the sacred feeling, due to their comparatively absorptive surface finishing materials and structural elements. The Aslanhane Mosque is a unique sacred structure within its era of construction, well-known with its wooden columns and ceiling. It is an important case for room acoustics analysis of such holy spaces. This study aimed to analyze the room acoustic measurement results of the Aslanhane Mosque, evaluating the intelligibility of speech and interpreting the sacred feeling created by reverberance, envelopment, and spaciousness, which are all crucial in such holy structures. It is revealed that although the Aslanhane Mosque's subjective rating for speech intelligibility is “good,” the overall low volume of the mosque and the lack of surface reflections decrease the sacred sensation. Additionally, the intelligibility of speech is vulnerable to obstacles within the line of sight, such as load-bearing columns. Lastly, it was observed that the increase in T30 at low frequencies improved the sacred sensation, envelopment, and spaciousness, without any profound negative impact on the intelligibility of speech.

木制亚式结构中的敬拜氛围和言语可理解度的声学特征:以阿斯兰汉清真寺为例
传统清真寺的声学设计面临双重挑战。首先,空间的内部气氛应该对使用者的整体和现象学空间感知产生神圣的感觉,这通常被认为是增加混响时间(T30)和低清晰度(C80)的直接影响。其次,语音应该足够清晰,这需要较低的T30和较高的语音清晰度,这与神圣气氛的最初关注背道而驰。我们假设在伊斯兰建筑中,木质的次要风格的清真寺可能会更好地符合语音清晰度的混响时间要求,同时保持神圣的感觉,这是因为它们具有相对吸收性的表面修饰材料和结构元素。阿斯兰汉清真寺(Aslanhane Mosque)在其建筑时代是一个独特的神圣建筑,以木柱和天花板而闻名。这是对此类神圣空间进行房间声学分析的重要案例。这项研究旨在分析Aslanhane清真寺的室内声学测量结果,评估语音的清晰度,并解释由回响,包络和宽敞感所产生的神圣感觉,这些在这些神圣的结构中都是至关重要的。据透露,尽管阿斯兰汉清真寺的语音清晰度的主观评价为“良好”,但清真寺的总体体积较小且缺乏表面反射会降低神圣感。另外,语音的清晰度容易受到视线内的障碍物的影响,例如承重柱。最后,观察到低频下T30的增加改善了神圣的感觉,包络,
