摘要 对声音定向传输中的失真问题进行分析和实验。从理论上分析了声音在空气中传播时声源信号的幅值与谐波失真的关系;实验验证说明了这一失真现象及其数值关系;提出了利用预处理方法减小失真的解决方案。 Distortion of directional propagation of audio signal is investigated. The relation between distortion and audio signal is analyzed, and experimental results are showed. It is concluded that preprocessing of the original signal is necessary in order to reduce distortion.
