Reduction of acoustic cavitation noise emission with textile materials
Niniejszy artykuł przedstawia badania redukcji poziomu dźwięku poprzez zastosowanie materiałów tekstylnych wokół rurociągów. Źródłem hałasu jest szum kawitacyjny. W celu wyznaczenia spadku poziomu hałasu dla materiału izolacyjnego ułożonego wokół rury – geometria cylindryczna – zmierzono spektrum widma akustycznego w zakresie słyszalnym przez człowieka. Pomiary przeprowadzono dla materiałów tekstylnych ułożonych z różną ilością warstw wokół źródła szumów. Zaobserwowano spadek poziomu szumów charakterystyczny dla prawa masy. W ramach opracowania wyników wyznaczono wzór empiryczny opisujący względną redukcję poziomu szumów dla badanych materiałów.
This article presents an examination of the acoustic noise level reduction in piping applications. Hydraulic cavitation is the source of the noise. In order to determine the noise level drop for the insulating material arranged around the pipe – cylindrical geometry – the acoustic spectrum was measured in the range of audible frequencies. Measurements were made for textile materials stacked with varying amounts of layers around the source of noise. There was a decrease in the noise level characteristics for mass law. An empirical formula describing the relative noise reduction for the materials under study was proposed.
