The group of subjects included children over 7 years old and adults, whose success in rehabilitation made it possible to perform a full range of tests. The patients underwent tonal threshold audiometry and speech audiometry in a free sound field; the results obtained were registered in special MS Excel tables and further analysed using statistical methods.</p> <p><bold>Results.</bold> There were no statistically significant differences in hearing thresholds on tonal audiometry when using the coding strategies ACE and CIS, however, differences in speech perception were observed on average by 4.2%. The patients experienced in using hearing aids reported improved speech recognition, with scores varying within 5%.</p> <p><bold>Conclusion.</bold> Using a higher-resolution coding strategy can significantly improve speech recognition, while lower-resolution coding is beneficial for patients with digital hearing aid experience.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – изучение влияния на звуковосприятие стратегий кодирования звука ACE и CIS у пациентов с системой кохлеарной имплантации Cochlear.</p> <p><bold>Материал и методы. </bold>В исследование были включены 50 пациентов, проходивших реабилитацию на базе Астраханского филиала ФГБУ НМИЦО ФМБА России в течение последних 5 лет (с 2014 по 2019 гг.). В группу обследуемых вошли дети старше 7 лет и взрослые, успехи в реабилитации которых позволяли выполнить полный набор тестов. Пациентам выполнялись тональная пороговая аудиометрия и речевая аудиометрия в свободном звуковом поле, полученные результаты вносились в специально созданные электронные таблицы в программе MS Excel и подвергались статистическому анализу.</p> <p><bold>Результаты. </bold>Выявлено отсутствие статистически значимых различий порогов слуха на тональной аудиометрии при использовании стратегий кодирования ACE и CIS, однако наблюдались отличия в восприятии речи в среднем на 4,2%. Пациенты, имевшие опыт использования слуховых аппаратов, отмечали улучшение разборчивости речи, показатели отличались в пределах 5%.</p> <p><bold>Заключение.</bold> Использование стратегии кодирования с более высокой разрешающей способностью позволяет значимо чаще улучшить разборчивость речи, а с более низким разрешением дает преимущество пациентам с опытом использования цифровых слуховых аппаратов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cochlear implantation</kwd><kwd>hearing loss</kwd><kwd>audio coding strategies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кохлеарная имплантация</kwd><kwd>тугоухость</kwd><kwd>стратегии кодирования звукового сигнала</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Djourno A, Eyries C, Vallancien B.
