Noise Motor Working Tools and their Measures for Noise Reduction during Construction of Buildings

Abstract:

This article seeks to highlight the problem regarding noise emitted by chain saws and then solves the limitation of noise, but also try out the various elements that should prevent the spread of noise from those tools. The issue is solved in terms of the applicable standard requirements. It describes elements that were used as to prevent spreading noise. Finally, results from measurements demonstrate applicability of proposed elements in terms of reduction of sound power level. This article deals with the construction noise and builds on ongoing research in this area. For this research can then make some other experiments, follow up on the results.
