古筝拾音的最佳方位研究

Study on the Best Recording Positions of Guzheng

采用客观测算及主观评价相结合的方式,基于乐器的声压级辐射特性与谐和性指向特性对古筝的最佳拾音位进行分析.这种最佳拾音位的设置既可保证较大的响度,又可获得较好的音质.实验结果表明:古筝的最佳拾音位位于乐器的左侧及左侧偏上的位置,或者乐器的正前上方及上方偏右的位置.

Guzheng＇s optimal recording positions were proposed based on the analysis of the directivity patterns of loudness and timbre,which were obtained through measurements and examined by listening tests.These recording positions can acquire sufficient loudness and euphonious timbre.The results showed that the best recording positions were located at the left and the upper left or the above and the upper right of Guzheng.
