ABSTRACT The aim of this study is to investigate the effect of morphologies and the structure of polyurethane-based coatings created by different colour pigments, on sound transmission loss properties. To achieve this goal, coatings were created in different concentrations of 5%, 7% and 9% with red, green, orange and yellow pigments. The coatings were applied on glass surfaces and the sound transmission loss was measured by an experimental arrangement containing a microphone and a decibel meter. The effect of surface tension energy, surface roughness, reflection percentages and concentration of pigments were found to be negligible on the sound transmission loss, whereas the LAB colour codes have a determining effect. In the scope of this study, a new method and mathematical model were created to help measure the sound transmission loss on a surface, in which sound signal was carried with a laser beam via a system created in the laboratory.

涂有聚氨酯基涂料的不同颜色表面传声损失性能的数学建模

摘要 本研究的目的是研究由不同颜色颜料制成的聚氨酯基涂料的形态和结构对声音传输损失特性的影响。为实现这一目标，涂料以 5%、7% 和 9% 的不同浓度与红色、绿色、橙色和黄色颜料混合而成。将涂层涂覆在玻璃表面上，并通过包含麦克风和分贝计的实验装置测量声音传输损失。发现表面张力能、表面粗糙度、反射百分比和颜料浓度对声音传输损失的影响可以忽略不计，而 LAB 颜色代码具有决定性影响。在本研究的范围内，
