Objectives: Voice is influenced by personality. However, it is still questionable which acoustic features are influenced by personality traits. This study aimed to investigate the relationship between acoustic characteristics and personality dimensions. Methods: Thirty-three participants with dysphonia and 33 participants without dysphonia were recruited to take part in this cross-sectional st...

Acoustic cardiography is an exciting, new, easy-to-use, modernized technology that incorporates already proven techniques of phonocardiography. Application of acoustic cardiography to clinical practice can improve diagnosis and management of heart failure patients. Its clinical use should help address some of the need for robust, inexpensive, and widely accessible technology for proactive heart...

The difficulty of applying conventional concepts of respiratory mechanics to high frequency ventilation (HFV) has so far inhibited its general acceptance by clinicians. The basis of an approach derived from an acoustic analysis of the ventilated patient is presented which may help to clarify the mechanism of action of HFV and offer some guidelines to its clinical application. The ventilator is ...

This tutorial will explain the pumping system speed of sound concept (how to account for acoustic velocity changes due to pipe wall flexibility and liquid properties), the definition of quarter-wave, half-wave, and higher order acoustic mode shapes, the importance of each mode shape, and examples of how to estimate these mode shapes and frequencies. The use of basic acoustics to identify and re...

Schaffert N, Mattes K, Effenberg AO. An investigation of online acoustic information for elite rowers in onwater training conditions. J. Hum. Sport Exerc. Vol. 6, No. 2, pp. 392-405, 2011. Presenting acoustic information has become increasingly interesting for technique training and control in various sports. In elite rowing, acoustic feedback is a new and promising application to optimize the ...

The design of acoustic models is key to a reliable connection between acoustic waveform and linguistic message in terms of individual speech units. We present an original application of concurrent constraint programming in this important area of spoken language processing. The application presented here employs concurrent constraint programming – represented by Mozart/Oz [1] – to overcome the p...

This paper describes a novel method for acoustic trapping of submicron particles in glass capillaries using secondary acoustic forces. By using preloaded larger particles (seed particles) to initiate clustering, trapping of submicron particles is greatly improved and can be accomplished at lower concentrations. As a potential application for this new method we demonstrate capture and enrichment...

Acoustic methods have progressed to the point that an acoustic typology of the motor speech disorders can be constructed from a parameteric assessment of the speech subsystems (e.g., phonation, nasal resonance, vowel articulation, consonant articulation, intonation, and rhythm). The results of this analysis can be interpreted in respect to global functions in speech (e.g., voice quality, intell...

The unidirectional acoustic boundary has a broad application prospect. Besides the acoustic metamaterial or the strongly nonlinear acoustic medium, which were applied in the realization of the unidirectional acoustic boundary, the present paper proposes another approach through the active control method, where the control source has the property of single directivity. In order to validate its e...
