Abstract

There are various measures currently in place to prevent the spread of coronavirus (COVID-19); however, in some cases, these can have an adverse effect on the acoustic environment in buildings. For example, transparent acrylic partitions are often used in eating establishments, meeting rooms, offices, etc., to prevent droplet infection. However, acrylic partitions are acoustically reflective; therefore, reflected sounds may cause acoustic problems such as difficulties in conversation or the leakage of conversation. In this study, we performed a prototyping of transparent acrylic partitions to which a microperforated panel (MPP) was applied for sound absorption while maintaining transparency. The proposed partition is a triple-leaf acrylic partition with a single acrylic sheet without holes between two MPP sheets, as including a hole-free panel is important to prevent possible droplet penetration. The sound absorption characteristics were investigated by measuring the sound absorption in a reverberation room. As the original prototype showed sound absorption characteristics with a gentle peak and low values due to the openings on the periphery, it was modified by closing the openings on the top and sides. The sound absorption performance was improved to some extent when the top and sides were closed, although there remains the possibility of further improvement. For this study, only the sound absorption characteristics were examined in the prototype experiments. The effects during actual use will be the subject of future study.

将透明微穿孔板应用于桌面丙烯酸隔板:原型设计案例研究。
目前有各种措施来防止冠状病毒(COVID-19)的传播;但在某些情况下,这些措施会对建筑物内的声学环境产生不利影响。例如,餐饮场所、会议室、办公室等通常使用透明的丙烯酸隔板来防止飞沫传染。然而,丙烯酸隔板具有声反射性,因此反射声可能会造成声学问题,如谈话困难或谈话泄漏。在这项研究中,我们制作了透明亚克力隔断的原型,并在其上应用了微穿孔板(MPP),以在保持透明度的同时实现吸音效果。拟议的隔板是三叶丙烯酸隔板,两块 MPP 板之间是一块无孔丙烯酸板,因为无孔板对于防止水滴渗入非常重要。通过测量混响室的吸声效果,对吸声特性进行了研究。由于外围有开口,原型的吸声特性显示出峰值平缓、数值较低的特点,因此对其进行了改进,关闭了顶部和侧面的开口。关闭顶部和两侧开口后,吸声性能得到了一定程度的改善,但仍有进一步改进的可能。在本研究中,原型实验只考察了吸音特性。实际使用时的效果将是今后研究的主题。
