Abstract: In work use of the flexible extended array on the basis of a wave guide in the form of a flexible wave guide with filling with any liquid is offered, distribution of acoustic fluctuations to a round wave guide is considered. Change of phase speed in a wave guide is analyzed at influence on it of a low-frequency signal. Schemes of processing signals are considered.

Keywords: the parametric array, the rating array, flexible wave guide, processing schemes.
