Nanofibrous Layer Influence on Sound Absorption of Nonwovens
Original language description
This paper deals with the acoustic behavior of a fibrous material with resonant nanofibrous layer. The damping fibrous material has been chosen with respect to structure parameters. The fiber diameter for more precisely pore size is the main factor to sound absorption amount when the density and thickness were kept constant. In case the nanofibrous layer is damped by longitudinal laid fiber web, the sound absorption coefficient increases with increasing mass per area of nanofibrous layers. Using melt blown damping material, the maximum of sound absorption is displaced in the direction of lower frequencies that are requested.

Vliv nanovlákenné vrstvy na zvukovou pohlivost netkané textilie
Czech description
článek se zabývá akustickým chováním vlákenných materiálů s rezonančními nanovlákennými vrstvami. Zkoumanými vlastnostmi, které mají významný vliv na činitele zvukové pohltivosti jsou průměry vláken, resp. velikost mezivlákenných pórů.
