Currently, on the global civil engineering, materials for walls, floors, ceilings from inside of residential buildings are selected according to the shape, color and sound absorption characteristics. This paper presents the results of complex analysis in terms of microscopic, chemical and acoustic properties for six types of materials based on polyurethane and wood. Before presenting the results of absorption-reflection acoustic characteristics a brief theoretical aspect of the transfer function method are show. With this new approach of combined analysis, the correlation can be made between: materials porosity by microscopic study, chemical composition by the FT-IR method and absorption-reflection characteristics of acoustic interferometer analysis..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
