Acoustical properties of densified compost derived from swine solid fraction

One of the problems that farmers have to deal with is animal garbage disposal. At the same time the increasing demand of acoustic performance of building materials, leads the research for new materials (Hosseini Fouladi et al., 2010). One of the main factors to consider in building construction is the sound absorption properties of the materials used. The aim of this study was to evaluate the acoustic characteristics of the solid fraction resulting from the solid-liquid separation of pig slurry in order to use this material in building construction.
