气流扬声器的声功率频率响应由位移振幅的频率特性决定。文中计算了不同共 振频率时的位移特性，共振频率愈高，将愈有利于扩展频响。气流扬声器若被用于 重播语言，则其共振频率至少应设在１２００～１５００赫。文中介绍用磁流体代替压缩 空气的冷却作用，以便测量电功率满负载时的位移振幅。结果表明，声功率的频响 和位移特性几乎一样，中、高频时，小电功率的位移特性比大电功率的要好。对２ 千声瓦气流扬声器进行了主观评价，在５．８公里处逐字逐句记录得到的可懂度是 ５０ ％。
The acoustic power frequency response of the airflow loudspeaker is determined by the frequency characteristics of the displacement amplitude. In this paper, the displacement characteristics of different resonant frequencies are calculated. The higher the resonant frequency, the more conducive to expanding the frequency response. Airflow speakers, if used to replay the language, should have a resonance frequency of at least 1200 to 1500 Hz. The paper describes the use of magnetic fluid instead of the cooling effect of compressed air in order to measure the displacement amplitude of electric power at full load. The results show that the frequency response and displacement characteristics of acoustic power are almost the same, and the displacement characteristics of small electric power are better than those of large electric power at medium and high frequency. A subjective evaluation of a 2-megawatt air-flow speaker was made, with a verbatim record of 50% at 5.8 km.
