dc.description.abstract | Electrospun micro and nanofibers produced via
electrospinning method were used for the sound absorption
purposes. Polymers were initially dissolved in
dimethyleformamide (DMF) or ethanol with a ratio of 80:20
and electrospun at 20 kV, 20 cm separation distance and 3
ml/hrs pump speed. The two-microphone transfer function
method of the B&K impedance tube was used to determine the
acoustical properties of the manufactured nanofibers at various
frequencies. The test results showed that the absorption
coefficients of nanofibers (~500 nm) drastically increased. The
reason behind this phenomenon may be attributed to the higher
surface area of nanofibers and their interactions with more
sound waves/air molecules. This result may open up new
possibilities for the sound absorption problems in many fields,
such as aircrafts, other transportation vehicles and
infrastructures. | en_US |
