耳声发射测量仪校准系统设计

耳声发射测量仪测量值的准确与否直接影响听觉疾病的检测和诊断。本文设计并实现一套耳声发射测量仪校准系统。基于PXI总线设备搭建硬件系统;基于LabVIEW语言开发校准软件;对某诊断型耳声发射测量仪进行校准实验。实验结果表明,该校准系统能够对耳声发射测量仪进行校准,可用于日常校准工作中。

The measurement value of otoacoustic emission measuring instrument directly affects the detection and diagnose of the hearing disease. A calibration system for OAE measuring instrument is designed. Building calibration system based on the PXI and developing the software structure based on LabVIEW language. Choose a insmament to verify the validity of the calibration system. The experimental results show that calibration system can calibrate the performance parameters 0fthe otoacoustic emission measuring instrument.
