Manufacturing and acoustical characterization of electrospun PolyVinylPyrrolidone (PVP) Blankets
In this work, new light soundproofing fibrous materials were obtained through electrospinning technique. The sound absorbers were obtained in the form of blankets of thin disks of 10 cm diameter, characterized by fibres with a diameter in order of 2 μm. Different activities involved for acoustical characterization of specimens, in particular to the evaluation of the sound absorption coefficient...
متن کاملAcoustic contributions of a sound absorbing blanket placed in a double panel structure: absorption versus transmission.
The objective of this paper is to propose a simple tool to estimate the absorption vs. transmission loss contributions of a multilayered blanket unbounded in a double panel structure and thus guide its optimization. The normal incidence airborne sound transmission loss of the double panel structure, without structure-borne connections, is written in terms of three main contributions; (i) sound ...

متن کاملElectrospun light-emitting nanofibers.
We have electrospun light-emitting nanofibers from ruthenium(II) tris(bipyridine)/polyethylene oxide mixtures. The electroluminescent fibers were deposited on gold interdigitated electrodes and lit in a nitrogen atmosphere. The fibers showed light emission at low operating voltages (3-4 V), with turn-on voltages approaching the band gap limit of the organic semiconductor. Because of the fiber s...
متن کاملSound Sensitivity of the Saccule for Low Frequencies in Healthy Adults
Approximately 80 years ago John Tait speculated about a possible auditory role for the otolith organs in humans those days, there was no direct evidence for that idea. This time is for us to review and research. Then, the objective of our study was to investigate saccular hearing in healthy adults. We selected twenty healthy controls and twenty-four dizzy cases. Assessment comprised of audiolog...
