Virtual acoustics and auralizations have been previously used to study the perceptual properties of concert hall acoustics in a descriptive profiling framework. The results have indicated that the apparent auditory distance to the orchestra might play a crucial role in enhancing the listening experience and the appraisal of hall acoustics. However, it is unknown how the acoustics of the hall in...

In this paper, a new formulation for acoustics coupled with linear elasticity is presented. The primary objective of the work is to develop a three dimensional hp adaptive finite element method code destinated for modeling of acoustics of human head. The code will have numerous applications e.g. in designing hearing protection devices for individuals working in high noise environments. The pres...

Our approach is inherently multi-disciplinary, blending the key disciplines of geology/geophysics (G&G) and acoustics, linked by the field of geoacoustics. For many years, the underwater acoustics community has probed sediment geoacoustics through inverse modeling of acoustic measurements (e.g., propagation, reverberation) or via empirical relations (e.g., Hamilton, 1980) or physics-based model...

The study of structural acoustics involves modeling acoustic radiation and scattering, primarily in exterior regions, coupled with elastic and structural wave propagation. This paper reviews recent progress in nite element analysis that renders computation a practical tool for solving problems of structural acoustics. The cost-eeectiveness of nite element methods is composed of several ingredie...

The Psittaciformes are a large order of landbirds comprising over 350 species in about 83 genera. In 2009, 141 published studies implicated parrots as research subjects; in 31 of these studies, 483 individuals from 45 different species could be considered laboratory animals. Amazons and budgerigars were by far the most represented psittacine species. The laboratory research topics were categori...

This paper presents the Acoustics Apps, an e-learning platform that offers interactive and playful environment for teaching learning principles of acoustics vibration. The Apps address increasing demand digitized methods, which might be suitable home schooling or as a complement to physical experiments by adding simulation. apps combine experimenting, observing, exploring using state-of-the-art...

The generalized likelihood ratio test (GLRT) for a stochastic partially homogeneous model is proposed for adaptive signal detection. The stochastic partially homogeneous model generalizes the standard partially homogeneous model by treating the disturbance covariance matrix as a random matrix. Specifically, it assumes that, R, the disturbance covariance matrix of training signals, is a random m...
