摘要

This paper deals with noise protection and the practical means to achieve this purpose. Individual working places, especially for construction machines with intensive and random dynamical working cycle require proper noise insulation because of the high level of acoustical pollution. The authors propose a feasible acoustic panel solution based on composites core thus that it will be assure proper noise isolation level for large area of applications in respect with the noise emissions characteristics and the spatial distribution and acoustic sensitivity of the receivers. The basic idea of this study combines selective quantitative and qualitative characteristics of a group of materials such as metal sheets, elastomers and textiles to obtain a proper performance of the panel ensemble.
