Research on Acoustic Sensitivity Testing Technology of Accelerometer

本文对加速度传感器的声灵敏度产生原因进行分析,介绍了以纯音噪声声场的声灵敏度测试系统。通过实验对声灵敏度由声场声压级变化和频率变化的响应进行研究,提出一种随机噪声声灵敏度合成模型,并对模型进行技术研究。

This article analyzes the reasons for the acoustic sensitivity of acceleration sensors and introduces a acoustic sensitivity testing system using pure tone noise fields.By conducting experiments to study the response of acoustic sensitivity to changes in sound pressure level and frequency in the sound field,a random noise acoustic sensitivity synthesis model is proposed,and technical research is conducted on the model.
