The paper concerns the quest to find acoustical parameters that describe properties of vocal fold functioning from professional singing to voice pathologies. Improved data handling within the framework of phonetogram recordings has been used to arrive at a better understanding of what acoustical parameters could tell us about vocal registers.

background: characterizing the mechanical properties of brain tissue is deemed important for developing a comprehensive knowledge of the mechanisms underlying brain diseases. mechanical properties of very soft tissues, such as brain until recently have been attracted the attention of researchers because these tissues do not tolerate mechanical loads. the mechanical properties of brain tissue, h...

This paper analyzes the interaction between the vocal folds and vocal tract at phonation onset due to the acoustical coupling between both systems. Data collected from a mechanical replica of the vocal folds show that changes in vocal tract length induce fluctuations in the oscillation threshold values of both subglottal pressure and frequency. Frequency jumps and maxima of the threshold pressu...

Modeling the acoustical process of soft biological tissue imaging and understanding the consequences of the approximations required by such modeling are key steps for accurately simulating ultrasonic scanning as well as estimating the scattering coefficient of the imaged matter. In this document, a linear solution to the inhomogeneous ultrasonic wave equation is proposed. The classical assumpti...

This paper describes an interdisciplinary project on room acoustics. The main goals of this project is to identify and analyse the relevant acoustical parameters for small rooms used for music production – concert halls, studios, lecture rooms, movie theatres, etc. – and, using modern methodologies for software development, build computational tools to evaluate and manipulate these parameters. ...

the purpose of this study is to survey cross section changes of the animal brain samples during the tension and compression tests and comparison of the experimental results for three animals: bovine, sheep, and rabbit. a linear elastic theory with considering the necking in tension and barreling in compression has been considered for brain tissue. bridgman method for tension and cross section u...
