The Effect of Measuring Equipment Settings on the Resonant Behavior of Nanofibrous Membrane

Popis výsledku v původním jazyce

Sound absorption materials are used to reduce sound pressure level to an acceptable level since high sound pressure level could create listening discomfort in the closed spaces. There are mainly four types of sound absorption materials available that canbe used as sound absorbers, namely, porous absorber, Helmholtz resonator, membrane absorber and perforated panel absorber. For low-frequency absorption, the structures based on the resonance principle of nanofibrous layers, are found to be relatively efficient in converting acoustic energy into thermal energy. Accordingly, the aim of this study is to discuss the sound absorption behavior of a nanofibrous resonant membrane, which is produced using a needleless electrospinning process, from PA6 solution.For this purpose, the resonant frequencies of the material were optically determined by measuring the size of the deflection with the use of a high speed camera. Finally, the effect of the measuring equipment settings on the resonant beh
