Sound absorption coefficient analysis and verification of weft-knitted spacer fabrics for noise reduction application

Strong sound absorption fabrics with a high degree of noise control engineering had high success in noise control engineering, but a study into the relationship between structural parameters and sound absorption is still to be investigated further. The coefficients were higher than 0. 5 above 1000 Hz and higher than 0. 8 above 2000 Hz, and the sound absorption coefficients of samples with increasing thickness and airflow resistance can be improved, as increasing thickness and airflow resistance increases, while the absorbance of two layer spacer fabrics produced by more yarns is similar to those of samples with more yarns.
