The paper considers equations describing the motion of a fluid in a porous medium under the action of an electric field in conditions of the formed turbulent mode of motion. Equations are given that describe the acoustic oscillations that occur in a fluid, the source of which can be not only an alternating, but also a constant electric field. The pulsating broadband acoustic oscillations arising under the action of a constant electric field can be spurious during the operation of electroacoustic transducers, which should be taken into account in their design. The results of field experiments on the model of an electroacoustic transducer confirm the theoretical results presented in the study. The stated theoretical and experimental results make it possible to solve the priority scientific–technical problem of designing and creating new types of acoustic emitters.

本文考虑了方程，该方程描述了在形成的湍流运动模式条件下，电场作用下多孔介质中流体的运动。给出了描述发生在流体中的声振荡的方程，其源不仅可以是交变的，而且可以是恒定的电场。在电声换能器的工作过程中，在恒定电场作用下产生的脉动宽带声振荡可能是虚假的，在设计时应予以考虑。在电声换能器模型上的现场实验结果证实了该研究中提出的理论结果。
