Previous investigators examined how architectural features of residences for adults with mental retardation contributed to the visual appearance of homelikeness. Acoustical characteristics of 18 residences for people with mental retardation were examined here. As part of a concurrent study, college undergraduates rated photographs of rooms in each house for their apparent homelikeness. Reverberation times in living and dining rooms were negatively correlated with mean homelikeness ratings. The less homelike rooms had reverberation times that may interfere with speech perception for some people and that were comparable with those found in larger public rooms (e.g., lecture halls). The larger reverberation times in these rooms were the result of insufficient sound absorption by these rooms' furnishings.
先前的研究人员探讨了智障成年人住所的建筑特征如何营造出类似家的视觉外观。在此，我们研究了18所智障人士住所的声学特征。作为一项同期研究的一部分，大学生对每所房屋中各个房间的照片进行了类似家的程度的评分。客厅和餐厅的混响时间与平均类似家的程度评分呈负相关。那些不太像家的房间，其混响时间可能会干扰一些人的言语感知，且与大型公共房间（如讲堂）中的混响时间相当。这些房间较长的混响时间是由房间内陈设吸音不足导致的。
