An innovative frictional sound automatic measuring system (FSAMS) was designed and used in this study to investigate the frictional sound generated when natural-fibre woven fabrics are rubbed together. Frictional sound measurements made using the automatic FSAMS were compared with those from a manual frictional sound measuring system (Manual FSAMS). The frictional sounds of four natural-fiber woven fabrics (i.e., cotton, linen, silk, and wool) were recorded; the Fast Fourier Transform method was used to convert time domain signals into frequency domain signals, and the maximum sound amplitude (MSA) and level pressure of the total sound (LPTS) of cotton, linen, silk, and wool were calculated. The results of a t test, analysis of variance, data reproducibility, and cluster spectrums measured from the four natural-fiber woven fabrics were compared for the two test equipment systems. The results from the t test and analysis of variance showed significant differences in the MSA and LPTS measured. Data reproducibility was superior to the automatic FSAMS compared with the manual FSAMS, and the cluster spectrums were more readily distinguishable.

W celu zbadania szumu generowanego podczas tarcia o siebie tkanin z włókien naturalnych zaprojektowano i wykorzystano innowacyjny, automatyczny system pomiaru dźwięku ciernego (FSAMS). Porównano wyniki otrzymane za pomocą FSAMS z wynikami otrzymanymi przy użyciu systemu manualnego (Manual FSAMS). Do badania użyto czterech tkanin z włókien naturalnych: bawełny, lnu, jedwabiu i wełny. Przeprowadzono analizę statystyczną otrzymanych wyników. Analiza danych wykazała, że wartości szumu zmierzone przy użyciu FSAMS były bardziej stabilne i reprezentatywne, niż te otrzymane przy użyciu Manual FSAMS, ponieważ w przypadku systemu manualnego na wyniki pomiaru ma wpływ czynnik ludzki i hałasy otoczenia, które powodują duże błędy eksperymentalne.
