Design of ready-made acoustic model library by two-dimensional visualization of acoustic space
This paper proposes the technique enabling a design of readymade library composed of high performance and small size acoustic models utilizing the method of visualizing multiple HMM acoustic models onto two-dimensional space (“COSMOS” method: aCOustic Space Map Of Sound), and providing one of these models without overburdening users. The acoustic space (as expressed in multi-dimensional future ...
متن کاملA High Order Approximation of the Two Dimensional Acoustic Wave Equation with Discontinuous Coefficients
This paper concerns with the modeling and construction of a fifth order method for two dimensional acoustic wave equation in heterogenous media. The method is based on a standard discretization of the problem on smooth regions and a nonstandard method for nonsmooth regions. The construction of the nonstandard method is based on the special treatment of the interface using suitable jump conditio...
متن کاملTheoretical analysis of the focusing of acoustic waves by two-dimensional sonic crystals.
Motivated by a recent experiment on acoustic lenses, we perform numerical calculations based on a multiple scattering technique to investigate the focusing of acoustic waves with sonic crystals formed by rigid cylinders in air. The focusing effects for crystals of various shapes are examined. The dependence of the focusing length on the filling factor is also studied. It is observed that both t...
متن کاملAcoustic Voice Measures in Benign Mass Lesions
Objectives: The present study aims to compare acoustic voice parameters in patients with vocal cord nodules, polyps, and normal subjects. Methods: In this cross-sectional case-control study, the participants were selected by convenience sampling, including 30 patients with vocal polyps group, 38 patients with vocal nodules for the second group, and 42 participants without voice pathologies a...
متن کاملAnalysis of Linear Two-Dimensional Equations by Hermitian Meshfree Collocation Method
Meshfree Collocation Method is used to solve linear two-dimensional problems. This method differs from weak form methods such as Galerkin method and no cellular networking and no numerical integration. Therefore, this method has no constraints such as the integration accuracy and the integration CPU time, and equations can be isolated directly from the strong form of governing PDE. The fundame...
