Development of functional carpet structures is vital to improve sound quality of human life in transportation vehicles, residential and occupational environments. In this research, pile length and loop density parameters of acrylic carpets were studied to examine the effect on sound absorption properties. Carpet samples, with two different pile densities and four different pile lengths were produced for experimental purposes. Carpets with longer piles and dense loops result in the best sound absorption rates. Acrylic carpets produced with medium length piles and low density loops, yield better results at higher frequencies. Carpet samples with shorter piles and dense loops provide better sound absorption properties at low-to-mid frequencies. It has been observed that loop density and pile length parameters affect sound absorption properties at all frequency ranges. Anova analysis revealed that the combined effect of loop density and pile length parameters is evident in the mid and high frequency ranges.
