Sound Insulation Properties of Polymer Soundproof Panels

open access: yesJournal of Korean Society of Environmental Engineers, 2013
It is widely known that the sound insulation of soundproof panel is highly correlated to two factors, surface density of material and the frequency of noise. Accordingly, the character of traffic noise released in actual situation is important requisite for determining thickness to determine surface density and material of soundproof panel.

Thermal insulation and sound absorption properties of fibrous layered structures

open access: yesJournal of Structural Engineering & Applied Mechanics, 2023
In this study, the effects of the addition of Activated carbon powder (ACP), Polyacrylonitrile nanofiber web (PAN), application of Plasma treatment (P), and the number of treatment layers on thermal insulation and sound absorption properties of fibrous structures have been examined and compared to each other. Bamboo and E-glass fibers have been used to

Sound Insulating Properties of Certain Building Materials [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1935
Transmission loss data obtained in the Johns-Manville Laboratories on various building constructions are reported. Almost all this data has been obtained on “room size” floors and partitions. The relation between such tests and “panel” tests is given where data is available.
