流阻测量为吸声材料产品质量的即时监控提供了一种新的方法，它的优点是：简便、快捷、经济。流阻测量的精度一方面依赖于流阻仪本身的系统精度，另一方面决定于利用标准流阻对仪器的校准。作者对各种可能的标准流阻材料进行了分析研究，最后确定使用玻璃管作标准流阻较为适宜，玻璃管标准流阻既有足够的精度又容易获得和制作。本文对平行玻璃管模型的流阻进行了理论分析和实验测量，结果表明实验和理论相当吻合。并利用标准流阻创造了一种新的流阻测量方法：比较法流阻测量。设计和制作了这种新的流阻仪，新流阻仪的测量精度达到了美国国家标准。
Flow resistance measurement provides a new method for instant monitoring of the quality of sound-absorbing materials. Its advantages are: simple, quick and economical. The accuracy of the flow resistance measurement depends on the system accuracy of the flow resistance meter itself on the one hand and the calibration of the instrument on the other hand using standard flow resistance. The author of all possible standard flow resistance materials were analyzed and studied, and finally to determine the use of glass tube as the standard flow resistance is more appropriate, the standard glass flow resistance both sufficient accuracy and easy access and production. In this paper, the theoretical analysis and experimental measurement of the flow resistance of the parallel glass tube model are carried out. The results show that the experiment and theory are in good agreement. And the use of standard flow resistance has created a new flow resistance measurement method: comparative method flow resistance measurement. The new flow resistance meter has been designed and manufactured. The accuracy of the new flow resistance meter has reached the national standard of the United States.
