Susilo, Nugroho and Kristanto, Luciana (2011) Investigation On The Role of Cavity and Slit of Cavity Resonators to Sound Absorption Behavior. In: Acoustic and Geophysics Cluster Meeting, March, 8, 2011, Surakarta.
Abstract
Slit resonator and also perforated resonator are few kind of room interior finishing. They act as sound absorbers. Gen-erally, they are constructed of at least three basic types of absorbers, such as porous, membrane and cavity compo-nents.These types of room surface finishing should acoustically provide aural quality for audience and even architec-turally contribute aesthetic value for interior finishing. To attain a well performance of interior finishing, composition of surfaces, textures and colors, motivate designers to explore slit and also perforated resonator as frequent choices. Configuration, dimension, composition and form of cavity or slit may give different and specific sound absorption be-havior as well as sound absorption ability and quality. Research that has been done leads to the objective to study the role of slit and cavity resonators as sound absorbers through experimental method in a reverberant chamber.
