The BB-modeled broadband stimuli consisted of stationary initial and final segments with a section of cyclic motion between them. Spatial effects were induced by changes in the interaural time difference (ITD). During the experiment, subjects assessed the position of the movement trajectory ends or the position of reference points using a graphic tablet. It was discovered that the perception of rhythmic movement of the sound image was significantly influenced by the integrative ability of the binaural auditory system. The results indicated that with instantaneous switching between stationary segments, the perceived positions of the trajectory ends (start point and turn point) matched the positions of the reference points. Conversely, the smooth movement between the same extreme values showed a displacement of the trajectory ends: the turn points were localized further from the reference points compared to the start points, at all trajectory positions in space. Localization of the trajectory end crucially depended on the time that the sound had stayed near the turning point. These patterns were expressed stronger in the central area of the acoustic space compared to the periphery.</p></abstract><trans-abstract xml:lang="ru"><p>Исследовали локализацию точек старта и поворота при ритмическом движении звукового образа, созданном путем моделирования бинауральных биений (ББ) широкополосных сигналов. Стимулы для моделирования ББ содержали начальный и конечный неподвижные участки и участок циклического движения между ними. Пространственные эффекты создавались путем изменений межушной задержки (Δ<italic>T</italic>). Во время эксперимента испытуемые оценивали положение концов траектории движения или положение неподвижных реперов с помощью графического планшета. Установлено, что интеграционная способность бинауральной слуховой системы существенно влияла на восприятие ритмического движения звукового образа. Результаты показали, что при мгновенном переключении между неподвижными участками воспринимаемое положение концов траекторий (точек старта, точек поворота) совпадало с положением реперов. При плавном движении между теми же крайними значениями наблюдалось смещение положения концов траекторий: точки поворота локализовались дальше от реперов по сравнению с точками старта при всех положениях траекторий в пространстве. Критическим фактором, определяющим локализацию концов траектории, являлось время нахождения звукового образа вблизи точки поворота. Полученные закономерности были значительнее выражены в центральной области акустического пространства по сравнению с периферической.</p></trans-abstract><kwd-group xml:lang="en"><kwd>binaural beats</kwd><kwd>cyclic motion</kwd><kwd>broadband signals</kwd><kwd>movement trajectory</kwd><kwd>sound localization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бинауральные биения</kwd><kwd>циклическое движение</kwd><kwd>широкополосные сигналы</kwd><kwd>траектория движения</kwd><kwd>локализация звука</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>24-25-00106</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Carlile S., Leung J.
