Description of the effective soundproofing panel is presented. For this panel, the ratio of acoustic characteristics and surface density exceeds many modern sound insulation and sound absorbing materials and structures. This article is devoted to modeling the sound absorption coefficient of the soundproof panel. The article presents formulas for determining the coefficient of sound absorption. Construction of a sound suppressed lightweight structured panel (SSLSP) developed by the authors is shown. Comparison of the effectiveness of the SSLSP panel and modern sound-proof materials is shown.
A model of a sound reflecting surface is presented that provides the specified character of the sound field formation. According to the pre-planned nature of the sound field for a specific area, the shapes of the reflecting surfaces are modeled, made and installed in a given order. For a point sound source, the shape of the reflecting surface is calculated, which is located at a given distance from the source and ensures the formation of a parallel sound stream in a given direction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
