Soundproofing performance of flexible polyurethane foams as a fractal object

Noise pollution is one of the most severe environmental concerns due to its damaging effects on human health. This study aimed to evaluate the relationship between the acoustic damping behavior and fractal dimension (D f ) of flexible polyurethane foams (FPUFs) manufactured by different synthesized...
