摘要

飞机飞行过程产生的噪声不仅会影响飞行员和乘客的飞行体验,而且可能会导致飞机结构的振动和声疲劳问题.根据飞机噪声测试中对传感器安装和采集设备小型化的要求,本文基于ADMP504传声器和FPGA高性能处理器,设计了一套便携式噪声测试系统.该系统可以实时采集飞机过程中的声压数据,为评估飞机飞行过程中的噪声载荷提供参考依据.
        The noise generated by the aircraft flight process does not only affect the flight experience of the pilot and passengers,but also probably cause vibration and sound fatigue of the aircraft structure. According to the requirements of miniaturization of sensor installation and acquisition equipment in aircraft noise test,this paper designs a portable noise test system based on ADMP504 microphone and FPGA high performance processor. The system can collect the sound pressure data in the process of aircraft in real time,and provide a reference for noise load evaluation during the flight.
