The present work was aimed at development of the technique for computerized diagnosis of pediatric bronchial asthma based on analysis of respiratory noises. Materials and methods. Computerized system for respiratory noise recording was used to receive sound signals from three points located in the mouth, above the trachea and above the right lung (on the front surface of the chest) in 51 pupils (aged 11,2 ± 3,2 years) suffering from bronchial asthma and in 22 healthy volunteers (aged 11,6 ± 2,5 years). Record of patient’s respiratory noises was fulfilled using electronic device with subsequent computational investigation of specific spectral characteristics of this sound. The technique for computerized diagnosis, permitting to perfect the possibilities of respiratory noise processing by means of fast Fourier transport (FFT), is offered in the paper. The suggested technique can be used for diagnosis of bronchoobstructive syndrome (BOS) in children with bronchial asthma. Results. There were suggested empirical criteria for balancing parameters of FFT spectrum, which allow us to develop software for automatic diagnosis of pediatric bronchial asthma. It was also indicated that computerized analysis of the respiratory noise spectrum power is of great diagnostic value (AUV varies from 0.783 to 0.895). The offered approach can be used for diagnosis of bronchial asthma (mainly in the oral cavity points and above the trachea) and for differential diagnosis between BA and other pulmonary diseases in the point above the right upper lobe. Conclusions. The suggested approach to analysis of respiratory noises can become one of additional techniques for BOS diagnosis. It can be used for remote monitoring of asthma patients in the regime of real time, as well as for control of treatment efficiency. Application with program can be inserted into the smartphone or low-cost embedded system for contactless analysis of respiratory noises that is important for remote diagnosis.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Развитие метода компьютерной диагностики бронхиальной астмы у детей, основанной на анализе дыхательных шумов. Материалы и методы. С помощью компьютеризированной системы для записи дыхательных шумов были получены звуковые сигналы с трех точек, расположенных во рту, над трахеей и над правым легким (по передней поверхности груди), у 51 школьника (возраст - 11,2 ± 3,2 г.), страдающего бронхиальной астмой, и 22 здоровых добровольцев (возраст - 11,6 ± 2,5 г.). Запись респираторных шумов пациента производилась с помощью электронного устройства с последующим численным исследованием специфических спектральных характеристик этого звука. В работе предлагается метод компьютерной диагностики, позволяющий усовершенствовать возможности обработки дыхательных шумов с помощью быстрого преобразования Фурье (БПФ). Предложенная методика может быть использована для диагностики бронхообструктивного синдрома (БОС) при бронхиальной астме у детей. Результаты. Были предложены эмпирические критерии для параметров выравнивания спектра БПФ, которые позволяют разработать программное обеспечение для автоматической диагностики бронхиальной астмы у детей. Также было показано, что компьютерный анализ энергии спектра респираторных шумов имеет большое диагностическое значение (AUV варьирует от 0,783 до 0,895). Предлагаемый подход может быть использован для диагностики бронхиальной астмы (БА) (главным образом, в точках в полости рта и над трахеей) и для дифференциальной диагностики БА с другими легочными заболеваниями в точке над правой верхней долей. Выводы. Предложенный подход к анализу дыхательных шумов может стать одним из дополнительных методов диагностики БОС при бронхиальной астме. Его можно использовать для удаленного мониторинга пациентов с астмой в режиме реального времени, а также для контроля эффективности лечения. Приложение с программой можно установить на смартфоне либо в малозатратной встроенной системе для бесконтактного анализа дыхательных шумов, что важно для дистанционной диагностики.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Bronchial asthma</kwd><kwd>children</kwd><kwd>respiratory noises</kwd><kwd>wheezing</kwd><kwd>computerized analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Бронхиальная астма</kwd><kwd>дети</kwd><kwd>дыхательные шумы</kwd><kwd>свистящее дыхание</kwd><kwd>компьютерный анализ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Фурман Е.
