Physical and Mathematical Models of Sound Attenuation in Porous Materials

Popis výsledku v původním jazyce

Ensuring of acoustic comfort belongs among the most important functions of building envelopes since too high level of noise may have negative effects on people living inside. Development of building elements with excellent acoustic properties is therefore one of objectives of current building industry. Methods of measurement, testing and evaluation of acoustic properties of building materials or construction are subjected to set of relevant standards. However, the standard procedures do not provide proper conditions for an effective research and development as they are time and cost ineffective. Utilization of modern techniques such as computational modelling of sound propagation and attenuation may represent the solution of this issue as it allows developing and testing the elements without being produced. At the same time, full- or semi-scale test constructions do not have to be built either within the development stage and they can be used effectively only for testing of final products in order to validate the results of computational modelling. Selection of proper mathematical and physical model is the crucial factor that ensures reliable data. The review of the available models is therefore presented in this paper, assessing each model briefly. Finally, the recommendation for selection of the model for description of sound propagation in porous materials is made.
