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...

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...

With a general decline in people's choosing to pursue science and engineering degrees there has never been a greater need to raise the awareness of lesser known fields such as acoustics. Given this context, a large-scale public engagement project, the 'Aeolus project', was created to raise awareness of acoustics science through a major collaboration between an acclaimed artist and acoustics res...

It could be said that Acoustics forms a bridge between speech production and speech perception, and as such it lies at the intersection of several speech communication related fields. The field of Speech and Hearing Sciences, for example, deals with speech production and speech perception. Speech Pathology also relates crucially to Acoustics. In addition, the linguistic fields of Phonetics and ...

Ambisonic impulse responses (also known as the Spatial Impulse Responses) are getting more and more popular in many applications of room acoustics. Measuring, modeling, synthesizing, or simulating acoustics of interiors with emphasize on their spatial features are the examples. The present article shows a methodology of room acoustics auralization assessment using the ambisonics technology. A c...

This paper presents a quantitative analysis of the relation between speech acoustics and the 2D video signal of the facial motion that occurs simultaneously. 2D facial motion is acquired using an ordinary video camera: after digitizing a video sequence, a search algorithm is used for tracking markers painted on the speaker’s face. Facial motion is represented by the 2D marker trajectories; wher...

Choir acoustics is but one facet of choir-related research, yet it is one of the most tangible. Several aspects of sound can be measured objectively, and such results can be related to known properties of voices, rooms, ears and musical scores. What follows is essentially an update of the literature overview in my Ph.D. dissertation from 1989 of empirical investigations known to me that deal sp...
