SHIELDING OF NOISE SOURCES USING ACOUSTIC SCREENS COMPOSED

The paper presents some experiments in which was used acoustic screens performed in two combinations of material layers. First variant of experimentation was the one in which the walls of the acoustic screens were performed by alternating the layers of OSB - mineral wool – plasterboard. In the second variant was used the combination layers of OSB - mineral wool - corrugated cardboard. The noise level measurements were made of the acoustic screen on construction type with three walls and three walls and lid. The recordings of the noise level were achieved by positioning the source in 4 measuring points and the microphone (receiver) in 16 points. Measurement results showed the best variant of work
