Title: Acoustical behaviour of a new lightweight partition made with gypsum board and cork
Issue Date: 1995
Abstract: The building construction development in Portugal has been changed by the gradual move to a general use of residential partitions made with increasingly light materials from the traditional heavy interior walls. A socioeconomic analysis of the Portuguese situation as it is concerned with the lodging policies and building construction industry, is briefly presented. An international comparison on this matter is shown using some economic parameters. The Portuguese situation is compared to 36 other countries. The main goal of this paper is to present a study of the acoustical behavior of lightweight partitions, especially those usually called sandwich-type'' and its experimental application to a new and very specific kind of partition made of gypsum board and cork, a traditional material in Portugal. This newly developed sandwich lightweight partition is presented and acoustically characterized. A new and simple mathematical model is presented to evaluate the sound isolation of this kind of partition. The results obtained in reverberant chamber tests are presented as well as the comparisons with the predicted values using the new model proposed. Different single and double wall types were tested giving STC values up to 44 dB. [Work supported by LNEC and Univ. of PortoPortugal.]
