介绍一种微脉冲压力传感器的基本工作原理，探讨了用压阻式微脉冲压力传感器配以多通道数据采集系统测量高声压级枪口噪声可行性，通过实验阐述了大口径机枪枪口噪声声压及其频谱分布规律，为研究高射机枪枪口噪声提供了依据
A basic working principle of a micro pulse pressure sensor is introduced. The feasibility of measuring muzzle noise of a high sound pressure level by using a piezoresistive micro pulse pressure sensor coupled with a multi - channel data acquisition system is discussed. The noise of a large diameter machine gun muzzle Pressure and its frequency spectrum distribution, provide a basis for studying the muzzle noise of a high-altitude machine gun
