摘要:
针对机载三维音频应用的实时性需求,提出了一种基于单耳相对头相关传递函数和改进型混响模型的机载三维音频快速实现方法,在较传统实现方式性能无明显下降的情况下降低了80%的计算量。对提出的算法在F-16战斗机模拟强噪声环境下进行相关主观试听实验,同时在某型飞机音频系统中实验验证。实验结果表明,所提方法在实时处理3路三维音频时,三维音频方位分辨精度在5°以内,可满足实际机载平台使用需求。

Abstract:
According to the real time requirement of 3D-audio in aviation,a fast method of 3D-audio in aviation based on single-ear relative Head Related Transfer Function(HRTF) and improved reverberation model is proposed.Compared with traditional implementations,the proposed method can reduce 80% of the calculation without reducing performance.The subjective experiment with the proposed algorithm is done under the F-16 simulated strong noise environment,and the proposed method is implemented in a certain aircraft audio system.The experimental results show that the proposed method can achieve the accuracy of 3D-audio azimuth resolution within 5° with processing three channels of 3D-audio at the same time and meets the requirement of actual use of airborne platform.
