EXPERIMENTAL DETERMINATION OF ACOUSTIC BEHAVIOR OF BUILDING MATERIALS BY MEANS OF ACCELEROMETERIC MEASUREMENTS

Popis výsledku v původním jazyce

In Central Europe, brick blocks with incorporated system of voids ensuring good thermal properties are widely used in the building industry. In the present, increasingly higher acoustic load gains on importance especially in the surroundings of places with high traffic load, places close to the airports or in urban areas. This fact should be taken into consideration in the design of constructions in order to ensure their good acoustic performance. The very first step of such design lies in the experimental determination of acoustic properties of the reference construction elements which are, if necessary, subsequently optimized by adjustment of the voids volume and geometry or filling of the voids by various bulk fillers ensuring a higher level of scattering of the propagating acoustic signal. In this paper, steel prism and brick block were subjected to measurements by accelerometers in the frequency range 1 – 10 kHz in order to compare acoustic behavior of materials with a significantly different structure. Finally, frequency-dependent displacements in accelerometers position, important input parameters for successive modeling, were calculated and compared.
