Abstract: The design indexes of hemi-anechoic room were proposed to achieve the acoustic environmental demand for measurement pilot’s head relation transfer function (HRTF), and designed with new compound panel absorber to build the hemi-anechoic room. Based on these designs, the ranges of free acoustic field have been maximized and the key acoustic indexes have been optimized within limited room. All of indexes are satisfied with correlative standard and some key indexes exceed the design indexes by NIM after hemi-anechoic room built. The hemi-anechoic room may furnish a free acoustic environment for HRTF measurement.

摘要： 为构建飞行员头部关联传递函数测量所需要的声学环境，提出用于飞行员头部关联传递函数测量的半消声室设计指标，并采用新型平板式复合吸声结构进行半消声室的设计和建造。所设计的半消声室在有限的建筑空间内达到自由声场空间的最大化和关键声学指标的最优化。半消声室建成并经过检测鉴定后，各项指标达到相关标准要求，某些关键指标优于设计要求。建成的半消声室提供飞行员头部关联传递函数测量需要自由声场环境，可以满足实验测量的需要。
