摘要

为了建立机载声音声功率溯源性，本文着重研究了机载声音的传播过程。研究了气动参考声源作为潜在传递标准。最初，这些来源是根据目前的需要进行审查的。研究的核心是从校准到原位条件过渡所需的校正。研究了大气压力、环境温度和风机转速对温度的影响，并确定了相应的修正量。还进行了与现有校正的比较。近场效应是研究的另一部分。相关的不确定性是用透明的方法估计的。给出了不确定度与原位和校准条件值的关系。

Study on the Properties of Aerodynamic Reference Sound Sources

Towards the establishment of traceability in sound power in airborne sound, the present study focuses on the dissemination procedure. Aerodynamic reference sound sources were studied as potential transfer standards. Initially, the sources were examined in the up-to-present requirements. The core of the study is the correction required for the transition from calibration to in situ conditions. The influence of atmospheric pressure, ambient temperature and fan rotation speed was investigated and the corresponding correction was determined. A comparison to an existing correction was also performed. Near field effects were another part of the study. The related uncertainty was estimated in a transparent approach. The dependency of the uncertainty on the in situ and calibration condition values is also presented.
