Corrigendum to Study on sound absorption behavior of multi-component polyester nonwovens: experimental and numerical methods. Textile Research Journal 2019; 89(16): 3342–3361. DOI: 10.1177/0040517518811940.

The authors noticed and regret for an error related to Equation (2).

In Section “Some models for airflow resistivity and impedance prediction”, eq. (2) should be α = 1 - | R | 2 = 1 - | Z s ρ 0 c 0 - 1 Z s ρ 0 c 0 + 1 | 2 rather than α = 1 - | R | 2 = 1 - | Z s ρ 0 c 0 - 1 Z Z ρ 0 c 0 + 1 | 2 as shown in the published article.

The authors would like to apologize for any inconvenience caused.
