| 中文摘要: |
| 目前空气声高声压的溯源存在空白，本文基于激光-活塞发声器法，研究采用激光直接测量高声压下活塞振速的方式，实现了180 dB下高声压的溯源，并通过实验验证了理论公式和结果的一致性，为高声压的绝对溯源提供了技术方法，保障了高声压量值的准确可靠。 |
| 英文摘要: |
| There is no research on the traceability of airborne high sound pressure calibration currently. Based on laser piston-phone method, traceability of airborne high sound pressure up to 180dB is realized by the measurement of piston velocity in a piston cavity using laser interferometer. Experiment results show the good coherence to theoretic formulas. It can support the traceability of airborne high sound pressure calibration and provides accurate value to high sound pressure metrology. |
