Corrigendum to “Fractal Model for Acoustic Absorbing of Porous Fibrous Metal Materials”

الملخص EN

In the article titled “Fractal Model for Acoustic Absorbing of Porous Fibrous Metal Materials” [1], Figure 12(b) in Section 4.1 (“Experiment and Verification of σ”) is blanked since it is an in-house apparatus of the Institute of Acoustics at the Chinese Academy of Sciences and was published without their permission.

In addition, the statement “The inner diameter of the measuring tube is greater than 95 mm and the minimum air velocity can reach 0.5 × 10−3 m/s” should be corrected to “The inner diameter of the measuring tube is 29 mm and the minimum air velocity can reach 0.5 × 10−3 m/s.”
