Özet

Fibrous textile materials are widely used in acoustic applications. However, the absorption of lower-frequency sound is problematic with fibrous material made up of coarser fibers. For this reason sound absorption materials effective at low frequencies are required. For low-frequency sound absorption the energy of sonic waves is absorbed by a thin nanofibrous layer in accordance with the principle of membrane resonance. This study deals with the acoustic behavior of a nanofibrous resonant membrane produced by needleless electrospinning. Using an experimental set-up involving a high-speed camera, it was attempted to predict the sound absorption behavior of a PVA nanofibrous membrane by determining its resonance frequency. The findings were compared with those from a homogeneous membrane structure in the form of a foil.
