The aim of this study was to determine the effect of door frame design and the method of gasketing on sound insulation properties of doors. Analyses were conducted on two designs of doors made of wood-based materials with an identical door leaf structure and a different door frame structure. Sound insulation properties of doors manufactured by Porta KMI Poland were measured at the Vibroacoustic Test Laboratory of the Ship Design and Research Centre in Gdańsk at the testing station comprising a system of echo rooms. The test was performed following the testing procedure specified in the PN-EN ISO 10140-2:2011 standard. Based on the analysis of testing results it was shown that the door frame structure and gasketing have a slight effect on changes in sound insulation properties of doors. In the case of doors with the presented designs acoustic quality of rooms separated by such a partition will be identical. The door design with a thinner frame should be recommended for manufacturing practice.
