摘要
针对声学风洞试验与研究使用的传声器主要技术需求,分析研究了对传声器的声压灵敏度级、频率响应、相频特性、指向性的校准具体方法,完成现场实验验证,形成了声学风洞传声器的计量保障技术途径和计量保障方案。
According to the main technical requirements for microphones used in acoustic wind tunnel tests and researches,the specific calibrating methods for the sound pressure sensitivity level,frequency response,phase frequency characteristics,and directivity of microphones were analyzed and verified,and field experiments were completed acoustic winds were formed. The metrological guaranteed technical method and metrological guaranteed project for microphones of acoustic wind tunnel are proposed.
