Введение. Разработка эффективных конструкционных материалов с улучшенными акустическими характеристиками актуальна для современной строительной индустрии. Учитывая многообразие международных строительных норм по звукоизоляции и звукозащите зданий, необходима систематизация современных методов изучения этих характеристик. Целью исследования был всесторонний обзор методов определения акустических характеристик в строительстве, а также анализ литературы и международных норм для повышения здоровья и комфорта городского населения.

Материалы и методы

Материалы и методы. В связи с многообразием и сложностью исследования акустических характеристик зданий, помещений и отдельных ограждающих конструкций в статье приведен анализ методов оценки данных характеристик. Выявлены ограничения на размеры помещений и звуковых частот для измерения времени реверберации. Показан процесс усовершенствования метода измерения акустического импеданса в трубе Кундта. Детально рассмотрена методология определения числовых параметров звукоизоляции в зданиях в результате исследования ограждающих конструкций с учетом спектров различных источников шума, расположенных внутри и снаружи здания. Выявлено, что существующие методы измерения ударного шума показывают плохую воспроизводимость в низкочастотном диапазоне. Анализ работ доказал, что характеристики отражения звука теоретически зависят от толщины и жесткости отражающей поверхности и ее поверхностной плотности.

Заключение

Заключение. Область применения строительных материалов с улучшенными акустическими характеристиками достаточно обширна. Дальнейшие исследования могут быть направлены на усовершенствование методов исследования характеристик звукопоглощения и звукоотражения.

Introduction

Introduction: The development of effective structural materials with improved acoustic characteristics is relevant for the modern construction industry. Considering the variety of international building standards for acoustic insulation and soundproofing of buildings, it is essential to systematize the modern methods of studying these characteristics. The purpose of the study was a comprehensive review of methods for determining acoustic characteristics in construction, as well as an analysis of literature and international standards to improve the health and comfort of the urban population.

Main part

Main part: Due to the variety and complication of the study of the acoustic characteristics of buildings, premises and individual walling, the article provides an analysis of methods for evaluating these characteristics. The limitations on the size of rooms and sound frequencies for measuring reverberation time have been identified. The process of improving the method of measuring acoustic impedance in Kundt’s tube is shown. The methodology for determining the numerical parameters of sound insulation in buildings using the study of building envelopes taking into account the spectra of various noise sources located inside and outside the building is considered in detail. It was found that existing methods for measuring impact noise show poor reproducibility in the low frequency range. The analysis of the works proved that the sound reflection characteristics theoretically depend on the thickness and rigidity of the reflecting surface and its surface density.

Conclusions

Conclusions: The scope of building materials with improved acoustic characteristics is quite extensive. Further research may be aimed at improving methods for studying the characteristics of sound absorption and sound reflection.
