Amplitudes Upon Reflection in Acoustical Experiments
This short note describes some simple acoustical wave experiments that explain the physics of reflection and transmission coefficient formulae for normal incidence P-waves. The experiments help us to understand the mathematical expressions for the reflection and transmission coefficients for displacement and pressure that are frequently used in seismology. Figure 1. The figure shows a boundary ...
متن کاملHow do minor acoustical cues affect male and female voice quality?
Speakers' sex identification scores were elicited in order to test the possible perceptual function of minor differentiating cues. The variable cues under investlgation, FO range and F3 location, were manipulated and presented to listeners in a pairwise comparison task. Minor F3 location variation yielded results in the expected direction, whereas FO range proved to be too small to be perceptua...
متن کاملAcoustical and topological experiments for an HMM-based speech segmentation system
Several specific tasks in the field of text-to-speech synthesis requires a huge amount of labeled speech corpora. Mostly, these labels correspond to phone marks aligned on the speech waveform. Different kind of solutions have been applied to this problem from rule-based systems to stochastic-based ones. We validate here a solution based on Hidden Makov Models. Various test configurations are pr...
متن کاملAxial vibrations of brass wind instrument bells and their acoustical influence: Experiments.
It has recently been proposed that the effects of structural vibrations on the radiated sound of brass wind instruments may be attributable to axial modes of vibration with mode shapes that contain no radial nodes [Kausel, Chatziioannou, Moore, Gorman, and Rokni, J. Acoust. Soc. Am. 137, 3149-3162 (2015)]. Results of experiments are reported that support this theory. Mechanical measurements of ...
متن کاملReproducibility experiments on measuring acoustical properties of rigid-frame porous media (round-robin tests).
This paper reports the results of reproducibility experiments on the interlaboratory characterization of the acoustical properties of three types of consolidated porous media: granulated porous rubber, reticulated foam, and fiberglass. The measurements are conducted in several independent laboratories in Europe and North America. The studied acoustical characteristics are the surface complex ac...
