These fabrics can play an important role in the development of acoustic materials considering folding techniques in the design phase. The folding of a cotton fabric not only affects the esthetic appearance but also directly influences the total absorption surface and the volumetric density. The aim of this research was to establish the influence of geometric design parameters, such as the number of folds and the textile length on the sound absorption properties. Experimental measurements were performed by using an impedance tube considering only incident plane waves. The diffuse-field sound absorption coefficient of several fabric configurations placed in front of a rigid backing forming an air-cavity between them was also measured in the small-sized reverberation chamber. A semi-empirical model based on the spacing between the fabric to the backing wall and the folding geometry was used in order to predict the diffuse-field sound absorption in reverberation room. Results showed a very good agreement between measured and predicted sound absorption coefficients.This research was financially supported by the Ministry of Economy and Innovation (MINECO) and the European Union FEDER through project FIS2015-65998-C2-2 and by project ACIF/2017/073 by Regional Ministry of Education, Culture and Sport of the Generalitat Valenciana and with the support of European Structural Investment Funds (ESIFEuropean Union);European Structural Investment Funds [ACIF/2017/073]Taylor & FrancisDepartamento de Física AplicadaDepartamento de Ingeniería Textil y PapeleraEscuela Politécnica Superior de AlcoyEscuela Politécnica Superior de GandiaCentro de Tecnologías Físicas: Acústica, Materiales y AstrofísicaInstituto de Investigación para la Gestión Integrada de Zonas CosterasGrupo de Investigación Gestión Integral en la Industria TextilGeneralitat ValencianaEuropean Regional Development FundMinisterio de Economía y CompetitividadRepositorio Institucional de la Universitat Politècnica de València Riunet20222022-12-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://riunet.upv.es/handle/10251/231791reponame:RiuNet.
