Abstract
The article presents a comparative analysis of determined spectralresponsesof the airborne sound insulation of single homogeneous baffles using computational and experimental methods. Calculations using theoretical models, such as mass law, the Sharp andDavymodels, SoundFlow software and laboratory tests concerned nineplates made of plastic,steel, aluminium and rubber, which arehomogeneous materials. These materialsare used in the construction of walls in vibroacoustic protection, such as acoustic barriers, machine operating field shields and sound insulating enclosures. Apart from analysing the spectral responsesof the sound insulation of theplates, the weighted single-number sound reduction indices Rw, calculated by using prediction methodsand laboratory measurements, were compared.Research has shown computational errors of about 6-7 dB for mass law and the Sharp model and about 3 dB for the Davy and Davy-Sharp models and SoundFlow software.
