A Pulse Tube for the Measurement of Acoustic Impedance [PDF]
The Journal of the Acoustical Society of America, 1953 An apparatus is described with which the acoustic impedance at an interface can be measured in water for normally incident sound. It consists essentially of a thick-walled steel tube 6 feet long with an internal diameter of 212 inches, which is mounted vertically and filled with water. A crystal transducer, mounted at the bottom of the tube, produces a

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Acoustic Absorption Coefficient of Oil Palm Midrib Composite
Jurnal Fisika FluxComposite from oil palm midrib waste is one of the natural fiber materials that can reduce noise. Its material sample composite with gypsum was placed inside an impedance tube, which fitted with the mass of palm midrib mill, i.e., 0.1 kg, 0.15 kg, and 0 ...
