Abstract

Sound absorbing materials are widely used to provide acoustic comfort in indoor places. Nowadays, many types of sound absorbing materials have been developed and mineral and polymer based natural, artificial and synthetic materials are used for the development of these materials. An important group of sound absorbing materials are the materials which have a porous structure. The most important part of these materials is the fibrous and cellular materials. This study is about the production of nonwovens from chicken feathers which have a cellular interior. In this way, it is possible to combine the properties of both cellular and fibrous materials. In this study, thermal bonding method was used to produce a nonwoven surface from chicken feathers for sound insulation. Polyester based bicomponent fiber was used to connect the fibers together. The bicomponent fibers were mixed with the chicken feathers at specific ratios to produce nonwoven surfaces with hot pressing method. The samples were rested under normal atmospheric conditions for 48 hours and samples were prepared to measure the sound insulation parameters in the impedance tube. The measurements were performed according to the standard and each sample was measured in single, double and triple layers to see how the sound insulation parameters changed depending on the material thickness. Examination of sound absorption parameters revealed that the developed material has the ability to absorb sound at high frequencies like all porous materials. Two and three layer samples showed the good results in terms of sound absorbing properties at medium and low frequencies. Developed materials are cheap and easy applicable materials and also light. Production of these materials from waste raw materials show that these materials are so attractive.
