Bandpass noise bursts (5–18 kHz) were used to create a signal and a masker. In the case of correlated stimuli, the same noise burst served both as a masker and a signal. In the case of uncorrelated stimuli, the signal and the masker were created from two different noise bursts. The masker was always on the right at an angle of 15 degrees. The signal was presented in one of three positions on the left: –18, –52, –86 degrees. The signal and the masker of 1 s duration each were presented either simultaneously or with a shift of the signal onset relative to the masker onset. The delay varied from 1 to 1200 ms. Perceived position of signals under masking conditions were compared with a single presentation of the signal. It is shown that under the masking conditions the perceived position of the signal shifted towards the masker, and the perceived position of the masker shifted towards the signal. The shift value decreased with increasing delay between the signal and the masker and with increasing angular distance between them. The mutual influence of the signal and the masker was more pronounced for correlated stimuli than for uncorrelated ones.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324874800">Исследовано влияние маскера на локализацию сигнала в условиях свободного звукового поля. Для создания сигнала и маскера были использованы шумовые посылки в диапазоне частот от 5 до 18 кГц. В случае коррелированных стимулов одна и та же шумовая посылка служила как маскером, так и сигналом. В случае некоррелированных стимулов сигнал и маскер создавались из двух различных шумовых посылок. Маскер всегда находился справа под углом 15 град. Сигнал предъявлялся в одном из трех положений слева: –18, –52, –86 град. Сигнал и маскер длительностью по 1 с предъявлялись либо одновременно, либо со сдвигом начала сигнала относительно начала маскера на задержку от 1 до 40 мс и на 1200 мс. Данные по локализации сигналов в условиях маскировки сравнивались с локализацией одиночного сигнала. Показано, что под действием маскировки воспринимаемое положение сигнала смещалось в сторону маскера, а воспринимаемое положение маскера – в сторону сигнала. Величина смещения уменьшалась с увеличением задержки между сигналом и маскером и с увеличением углового расстояния между ними. Взаимное влияние сигнала и маскера было сильнее выражено для коррелированных стимулов, чем для некоррелированных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>localization of the sound signal</kwd><kwd>masking</kwd><kwd>free field conditions.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>локализация звукового сигнала</kwd><kwd>маскировка</kwd><kwd>свободное звуковое поле.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Блауэрт И.
