Acoustic Calculation on Assemblage Gaps in a Noise Control

2010-4-29 Source：

Abstract: Acoustic splitters were used in noise control project for natural ventilation cooling tower in a power plant. In the interest of assemblage, two gaps were left between the acoustic splitters and the steel beams. Noise would leak from the gaps, but how much affection of these gaps would make? In this paper, the affection of these gaps will be analyzed through mathematical model.

Key words: assemblage gap; sound leak; sensitive spot; finite element；
