The pressure reflection factor can be calculated from the relative standard deviation of the sound pressure.
A solution satisfying the full Kutta condition and causality is derived from which the pressure reflection coefficient is calculated.
This paper reports the evaluation of a method for measuring the pressure reflection factor of an anechoic room lining in situ, proposed by Kuttruff and Bruchmuller.
A high pressure reflection high energy electron diffraction (RHEED) system (AOV Ltd), equipped with a differential pumping system was used to monitor in situ the surface evolution of the films.
The results obtained in terms of end correction, l, and magnitude of the pressure reflection coefficient, |R|, for an unflanged pipe model are in very good agreement with theoretical predictions and experimental data for the range of Mach numbers M≤0.15 and Helmholtz numbers ka≤1.5.
This is consistent with recent experimental observations that pressure reflection may be less important than previously thought (14).

First, the extreme impedance mismatch at the interface between the fatty attachments of the MFB and the bony elements of the TPC is essential, because it causes the greatest possible force to be exerted upon the bone from incoming sound pressure reflections.
Both 3-D and 2-D axisymmetric simulations are performed to demonstrate that the experiment is mostly driven by linear acoustic phenomena, including pressure wave reflection at the outlet and entropy-to-acoustic conversion in the accelerated regions.
Men who were still emotionally upset about their divorces showed increases in blood pressure upon reflection, while women generally did not.
However, AIx depends on the intensity of the reflected wave and as such it will depend on the diameter and elasticity of the small muscular arteries/arterioles at the major sites of pressure wave reflection.
Augmentation index (AI) is related to the timing of pressure wave reflection with regard to generated left ventricular systolic pressure.
