双簧管音孔压力检测设计

The design for oboe sound hole pressure measttrement

针对双簧管演奏的音质问题,设计了一种双簧管压力检测装置,对双簧管的音孔压力进行检测。该装置检测了3个音孔的压力,通过对不同演奏力度获得的压力数据进行分析。结果表明,在演奏过程中,音孔压力通过压力传感器采集并以电压信号输出,既有正压,也有负压,检测结果可为乐器生产者和演奏者提供参考。

An equipment for oboe sound hole pressure measurement was designed for the problems of timbre, this equipment had measured three sound holes＇ pressure,by analyzing the data of pressure which was acquired by different executants,the result showed that sound holes＇ pressure was collected by pressure sensor and exported as voltage signal,the pressure was altered by positive and negative.The measurement result may referenced by player and musical instrument designer.
