At present, after the restoration of independence, intensive construction of modern buildings for different purposes is being carried out within Lithuania. New effective materials and forms are being applied to these constructions. Proper usage of these materials improves vibroacoustic properties of buildings. The article deals with the vibroacoustic properties of applied building constructions depending on their forms and strengthening. Means to increase sound and vibration isolation without changing vibroacoustic properties of used materials have been determined. Examples of practical application of vibroacoustic properties of materials are given. The effectiveness of these materials has been determined. Theoretical results of the effectiveness of vibroacoustic properties of building materials coincide if the application of vibroacoustic properties in technologies of construction work is proper.
