The sound absorption coefficient and noise reduction coefficient of rice husk silica

This paper presents the acoustical behavior of rice husk silica samples in various composition and thickness by using epoxy and methyl ethyl ketone peroxide (MEKP) as binder. Rice husk is one of agriculture waste materials that can be obtained in a large quantity which have the potential in the appl...
