Research data for "Analysis of Sound Absorption Performance of Acoustic Absorbers Made of Fibrous Materials"

This dataset contains research data used to prepare the publication: Mirosław Meissner, Tomasz G. Zieliński, "Analysis of Sound Absorption Performance of Acoustic Absorbers Made of Fibrous Materials". Vibrations in Physical Systems, 2022, 33(2), 2022205 (8 pages). DOI: 10.21008/j.0860-6897.2022.2.05This research has been supported by the National Science Centre (NCN), Poland, under grant agreement 2021/41/B/ST8/04492.All data are provided in columns in ASCII (.dat) files.The files contain the results of numerical calculations of dependence of the normal absorption coefficient on a frequency for a material with the airflow resistivity of 1000 Pa*s/m^2 and the material thickness of 3, 5, 7, 10 and 15 cm.These results were obtained using the Dev-Pascal program and the Free Pascal Compiler ver. 3.2.2.The first column in each file is labeled "f(Hz)" and lists the sound frequency in Hz. The second column marked by "alpha" contains values of the normal absorption coefficient.
