    Nanofibrous Material as a High-Efficient Sound Absorbent

  • Original language description

    This paper deals with the sound absorption behavior of a fibrous material with resonant nanofibrous layer. The nanofibrous layer was produced by electrical spinning process and the resonance effect of nanofibrous layer has been studied. Sound wave vibrates the resonant nanofibrous system then the acoustic energy at the resonant frequency is converted partly to kinetic energy and the rest to acoustic energy at other frequencies. These frequencies are damped so that the most of acoustic energy, accumulated into the resonator, can be converted to heat. The sound absorption coefficient and resonant frequency of nanofibrous sample are given by its area density and size of air gap between the nanofibrous layers and rigid wall. Nanofibrous layers are comparedwith polyethylene foils where all parameters were kept constant.

    Nanovlákenný materiál jako vysoce účinný zvukový absorbent

  • Czech description

    V tomto příspěvku byl zkoumán rezonanční efekt nanovlákenných vrstev v závislosti na jejich plošné hmotnosti a jejich vzdálenosti od stěny, přičemž výsledky bylyporovnávány s polyetylenovými fóliemi o stejných parametrech jako mají nanovlákenné vrstvy.
