The shooters fired 30 shots from the AK74M in short bursts (2-3 shots in a burst) at targets when performing shooting exercises from three positions: from the knee, standing and lying down, in a free acoustic field without the use of personal protective equipment of the hearing organ. All participants were examined for distortion-product otoacoustic emissions (DPOAE) before and after firing from small arms. The method of binary logistic regression was used to develop a predictive model.</p> <p><bold>Results.</bold> A mathematical model has been developed to assess the probability of developing hearing loss according to the indicators of DPOAE before exposure to the noise of small arms. This model, with a standard classification threshold of p = 0.5, has an accuracy of 83.3%, sensitivity of 79.0%, specificity of 88.0%. According to the results of the ROC analysis for the resulting model, the area under the characteristic curve was equal to 0.924 (0.834;1.0), which indicates the excellent quality of the mathematical model.</p> <p><bold>Conclusion.</bold> The most significant were the signal/noise indicator (dB) at a frequency of 4.2 kHz on the left and the level of otoacoustic emission (dB) at a frequency of 4.2 kHz on the left before noise exposure. These indicators, as well as the age of the shooter, allow us to assess the probability of developing hearing loss.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – проанализировать показатели отоакустической эмиссии на частоте продукта искажения (ОАЭЧПИ) у лиц, подвергающихся воздействию шума стрелкового оружия, и на основании наиболее значимых из них определить вероятность развития тугоухости.</p> <p><bold>Материал и методы.</bold> Обследовано 30 добровольцев-стрелков мужского пола (60 ушей) возрастом от 19 до 30 лет. Стрелками производилось по 30 выстрелов из автомата АК74М короткими очередями (по 2–3 выстрела в очереди) по мишеням при выполнении упражнений учебных стрельб из трех положений (с колена, стоя и лежа) в условиях свободного акустического поля без применения средств индивидуальной защиты органа слуха. Всем обследуемым выполнялось исследование отоакустической эмиссии на частоте продукта искажения (ОАЭЧПИ) до и после стрельбы из стрелкового оружия. Для разработки прогностической модели использовался метод бинарной логистической регрессии.</p> <p><bold>Результаты.</bold> Разработана математическая модель для оценки вероятности развития тугоухости по показателям ОАЭЧПИ до воздействия шума стрелкового оружия. Данная модель при стандартном пороге классификации р=0,5 имеет точность 83,3%, чувствительность 79%, специфичность 88%. По результатам ROC-анализа для полученной модели площадь под характеристической кривой была равна 0,924 (0,834;1,0), что говорит об отличном качестве математической модели.</p> <p><bold>Выводы. </bold>Установлено, что наиболее значимыми являются показатель сигнал/шум (дБ) на частоте 4,2 кГц слева и уровень отоакустической эмиссии (дБ) на частоте 4,2 кГц слева до шумового воздействия. Данные показатели, а также возраст стрелка позволяют оценить вероятность развития тугоухости.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hearing loss</kwd><kwd>high intensity noise</kwd><kwd>acoustic impact</kwd><kwd>otoacoustic emission</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тугоухость</kwd><kwd>шум высокой интенсивности</kwd><kwd>акустическое воздействие</kwd><kwd>отоакустическая эмиссия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ryzhikov MA, Kuznetsov SM, Logatkin CM, et al.
