Luchinin Institute of Applied Physics, Russian Academy of Science, Nizhny Novgorod, Russia Key words: excitation and propagation; acoustical monitoring Abstract: The results of the studies of excitation and propagation of low-frequency acoustic fields in a shallow sea, which have been carried out at the IAP RAS for several years, are discussed. A novel equipment complex designed specially for these experiments and intended for the selective excitation and reception of waveguide modes is described. Examples of measurements of various characteristics of low-order mode acoustic signals are given, which demonstrate high efficiency of the applied equipment and measurement technique.
