Dataset of Sound Absorption Coefficients of Panels Made from Textile Waste

This dataset provides experimental results of sound absorption coefficients for sound-absorbing panels developed from textile waste materials. A total of five panel types were manufactured from different textile compositions: wool, polyester, linen, cotton, and a mixed sample (composed of 50% polyester, 30% cotton, 10% wool, 5% linen, and 5% other fiber blend). Measurements were carried out using the impedance tube method, covering a wide frequency range (6.25 - 6393.75 Hz). For each material type, three test specimens were prepared.

Two datasets are provided:
• Raw_data.xlsx — contains the unprocessed sound absorption coefficient values ​​measured for each frequency and measurement repetition.
• Mean_SD.xlsx — contains the averaged (Mean) sound absorption coefficient values ​​with corresponding standard deviations (SD) calculated across all repetitions.

These data support the evaluation of the acoustic performance of sustainable materials and enable comparison with conventional sound-absorbing products. The dataset can be used for further research in circular economy applications, eco-friendly acoustic material design, and environmental engineering studies.
