摘　　要：一个中性自然的听音环境要求听音房间的频率响应满足规定的特性。这些特性在一系列音频相关的国际标准中有详细的规定。对随机抽取的7个音响爱好者的家庭听音室进行详细的房间响应测量,依照AES推荐技术文档进行横向对比研究找到了一些共性。研究发现,大部分家庭听音室都存在第一阶反射声过大问题,若干频段吸声过强或不足,在中低频段都受到驻波的较大影响,导致房间响应超过标准技术文档的容差范围,因此需要在吸声材料的选择和位置的布置方面进行改善。A neutral listening environment requires the frequency response of the listening room to meet the specified characteristics.These features are specified in a number of audio related international standards.In this paper,detailed room response measurements were made in 7 randomly selected family listening room of HiFi fans,and a comparative study was conducted in accordance with AES recommended technical documentation to find some commonalities.It is found that most of the family listening rooms have the problem of excessive first-order reflected sound,and the sound absorption of some frequency bands is too strong or insufficient,which is greatly affected by standing waves in the middle and low frequency bands,resulting in the room response exceeding the tolerance range of standard technical documents.Therefore,it is necessary to improve the selection and arrangement of sound absorbing materials.
