Наиболее доступными и массово применяемыми являются системы с использованием пористых материалов. Установлено влияние вида, размера, характера пор, а также фазового состава образцов пористой стеклокерамики, полученных из цеолитсодержащих пород, на ее звукопоглощающие свойства.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Результаты экспериментальных исследований получены импедансным методом, а также методами рентгенофазового анализа, световой микроскопии, рентгеновской микротомографии и др.</p></sec><sec><title>Результаты</title><p>Результаты. Исследованы пористые стеклокерамические материалы маркой по средней плотности D250 и D300, классом по прочности на сжатие B3,5, с коэффициентом теплопроводности от 0,066 до 0,079 Вт/м∙°C и рекомендованной максимальной температурой применения до +850 °C. Общая пористость испытанных образцов стеклокерамических материалов составила от 87,7 до 90,1 %, количество открытых пор от 5 до 18,3 %. На значения звукопоглощающих свойств образцов пористой стеклокерамики основное влияние оказывает открытая пористость материала. С увеличением данного показателя с 4,5 до 18,3 % коэффициент звукопоглощения материала увеличился в зависимости от диапазона звуковых частот в 1,5–2 раза.</p></sec><sec><title>Выводы</title><p>Выводы. Пористая стеклокерамика, полученная из цеолитсодержащих пород, имеет хорошие физико-механические свойства и высокую температуру применения (не менее +850 °С), а при обеспечении высокого показателя открытой пористости может быть рекомендована для применения в качестве звукопоглощающих материалов в объектах строительного назначения и машиностроении.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Sound-absorbing systems are widely used in construction, reconstruction, repair of industrial and civil facilities, as well as in mechanical engineering. The most affordable and widely used systems are those using porous materials. The influence of the type, size, nature of pores, as well as phase composition of porous glass-ceramic samples obtained from zeolite-containing rocks on its sound-absorbing properties was established.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The results of experimental studies were obtained by the impedance method, as well as by methods of X-ray phase analysis, light microscopy, X-ray microtomography, etc.</p></sec><sec><title>Results</title><p>Results. Porous glass-ceramic materials with average density grades D250 and D300, compressive strength class B3.5, thermal conductivity coefficient from 0.066 to 0.079 W/m∙°C and recommended maximum application temperature up to +850 °C were investigated. The total porosity of the tested specimens of glass-ceramic materials was from 87.7 to 90.1 %, and the number of open pores from to 18.3 %. The sound-absorbing properties of porous glass-ceramic specimens are directly dependent on the open porosity of the material. With an increase of this indicator from 4.5 to 18.3 %, the sound absorption coefficient of the material increased 1.5–2 times, depending on the range of sound frequencies.</p></sec><sec><title>Conclusions</title><p>Conclusions. Porous glass ceramics obtained from zeolite-containing rocks have good physical and mechanical properties and a high application temperature (at least +850 °C), and with a high open porosity index, it can be recommended for application as sound-absorbing materials in construction and mechanical engineering facilities.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пористая стеклокерамика</kwd><kwd>звукопоглощающие свойства</kwd><kwd>коэффициент звукопоглощения</kwd><kwd>импедансная труба</kwd><kwd>рентгенофазовый анализ</kwd><kwd>рентгеновская микротомография</kwd><kwd>цеолитсодержащие породы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>porous glass ceramics</kwd><kwd>sound-absorbing properties</kwd><kwd>sound absorption coefficient</kwd><kwd>impedance pipe</kwd><kwd>X-ray phase analysis</kwd><kwd>X-ray microtomography</kwd><kwd>zeolite-containing rocks</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках реализации гранта Российского научного фонда (проект № 21-79-10422).</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of a grant from the Russian Science Foundation (project No. 21-79-10422).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Герасимов А.И.
