Title: Simplified calculus to estimate the acoustical absorption of non-planar materials
Authors: Pfretzschner, Jaime; Rodríguez Alves, Rosa M.ª; Colina, Carlos de la
Issue Date: Mar-1999
Publisher: Deutsche Gesellschaft für Akustik
Citation: 137th Meeting of the Acoustical Society of America. Architectural Acoustics ; 10
Abstract: A simplified model for the acoustical absorption coefficient valid for non-planar surfaces of porous material is developed. This model is tested with experimental arrangements for granular specimens.
