Sound Insulation Property of Warp Knitted Fabrics
Advanced Materials Research, 2012In this study, a test device was designed and established for evaluating the sound insulation of fabrics, and six warp knitted fabrics with different parameters were chosen and tested. The results show that these fabrics have different sound insulation effect to various sound wave frequencies, and normally, the fabric with solid structure has better ...

Advanced Materials Research, 2014
The paper is focused on the issues of sound insulation properties of the facade elements which are currently applied mainly at industrial hall buildings. Requirements for the sound insulation properties of these buildings are requested not only from users themselves, but also from residents of surrounding objects, who are often disturbed by operation ...

The Study of Sound-Insulating Properties of Fibrous Materials
Occupational Safety in IndustryThe results of an experimental study of sound-insulating properties of fibrous materials have been provided. A simplified methodology to measure the air noise insulation of fibrous materials has been proposed. An installation to implement the methodology includes a small-size chamber sound-insulated from the environment, a sound generator, and a sound ...

SOUND PERMEABILITY AND SOUND INSULATION PROPERTIES OF OUTER WALL APPLICATIONS
2014Closed volumes continue with our lives a certain sound level. Sound, as long as desired at this level of human impact on the positive. Therefore, in the structure of sound, the comfort level must be brought under control. This, however, to provide a rational selection of materials and methods used in accordance with the relevant physical concepts and ...

Sound insulation properties of sandwich structures on glass fiber felts
Fibers and Polymers, 2015This paper focuses on three types of glass fiber felt sandwich structures to identify the optimal sound insulation structure. Air flow resistivities of glass fiber felts are 6633 Pa·s/m2 (Loose), 19579 Pa·s/m2 (Mid) and 42724 Pa·s/m2 (Dense), respectively. The three types of sandwich structures are dense-mid-loose (DML), mid-loose-dense (MLD) and loose-

Thermal and sound insulation properties of pumice/polyurethane composite material
Emerging Materials Research, 2020This study aimed to create a flexible composite material that can be used in special environments where heat and sound insulation is desired. Pumice with a grain size of 4.76–2.38 mm was mixed with 10, 20, 30, 40 and 50% polyurethane by volume. Sound absorption coefficient, sound transmission loss coefficient and thermal conductivity coefficient tests ...
