Determination of resonant frequencies of nanofibrous membrane by highspeed camera
Original language description
Nanofibrous layer performed as a membrane is capable of vibrating at low frequencies due to its small interfibrous spaces and planar arrangement brought into forced vibrations upon impact of sound waves of low frequency. The resonance of the nanofibrous elements allows acoustic energy to be converted into thermal energy. In this paper, a nanofibrous layer was produced by an electrospinning process from the water solution of polyvinyl alcohol (PVA). The PVA nanofibrous membranes of two different fiber diameters were made and the effect of membrane resonance has been studied. For a purpose of resonance and sound absorption properties of nanofibrous membrane, the two methods have been used. The optical method containing high-speed digital camera has been used for resonant frequencies of nanofibrous membrane determination. Two-microphone Impedance Measurement Tube Type 4206 was used to measure the sound absorption coefficient. Moreover, the nanofiber diameter of membrane has been evaluated.
