   <abstract xml:lang="ru">
    <p>Освоение шельфовых районов моря приводит к вмешательству человека в сложившиеся экосистемы и ставит под угрозу жизнь морских млекопитающих. Изучение, анализ и систематизация звуков китообразных может дать возможность идентификации вида и количества особей. С другой стороны, киты являются излучателями самых низкочастотных звуков в волноводе. Если известно расположение источника и приемника, частотно-временной анализ звукового поля может быть использован для инверсии акустических свойств морского дна. В работе приводится обзор видов морских млекопитающих - усатых китов и излучаемых типов высокочастотных и низкочастотных звуков. Проводится частотно-временной анализ излучаемых усатыми китами звуков. Результаты представляются в виде временных реализаций и спектрограмм. Показывается, что волноводные условия распространения звука вносят специфические дисперсионные искажения. Между излученным и зарегистрированным с помощью гидрофона звуком может быть большая разница. Показывается принципиальная возможность использования низкочастотных звуков млекопитающих для решения задач инверсии акустических свойств морского дна.</p>

    <p>The development of offshore areas of the sea leads to human intervention in the existing ecosystems and threatens the life of marine mammals. The study, analysis, and systematization of cetacean sounds can make it possible to identify the species and number of individuals. On the other hand, whales are the emitters of the lowest frequency sounds in the waveguide. If the location of the source and receiver is known, time-frequency analysis of the sound field can be used to invert the acoustic properties of the sea floor. The paper provides an overview of the species of marine mammals - baleen whales and radiated types of high-frequency and low-frequency sounds. The frequency-time analysis of sounds emitted by baleen whales is performed. The results are presented in the form of time implementations and spectrograms. It is shown that waveguide conditions of sound propagation introduce specific dispersion distortions. There can be a big difference between the sound emitted and recorded using a hydrophone. The paper shows the principal possibility of using low-frequency mammalian sounds to solve problems of inversion of acoustic properties of the sea floor.</p>
