Investigating the Potential Use of EEG for the Objective Measurement of Auditory Presence
Applied Sciences, 2022 Presence is the sense of being in a virtual environment when physically situated in another place. It is one of the key components of the overall virtual reality (VR) experience, as well as other immersive audio applications.

Broadband Acoustic Collimation and Focusing using Reduced Aberration Acoustic Luneburg Lens [PDF]
, 2020 Acoustic Luneburg lens is a symmetric gradient-index lens with a refractive index decreasing radially from the centre to the outer surface. It can be used to manipulate acoustic wave propagation with collimation and focusing capabilities. However, previously studied acoustic Luneburg lens works only at audible frequency ranges from 1 kHz to 7 kHz, or ...

Symmetry selective directionality in near-field acoustics
National Science Review, 2020 Understanding unidirectional and topological wave phenomena requires the unveiling of intrinsic geometry and symmetry for wave dynamics. This is essential yet challenging for the flexible control of near-field evanescent waves, highly desirable in broad ...

Some information on acoustic topological insulator [PDF]
arXiv, 2023 In this exceedingly short review article, we have provided some information on acoustic topological insulator for pedagogical purpose. Since, intrinsically acoustic systems do not have Kramers doublets due to spin-zero status, artificially acoustic spin-half states could be engineered as reported in refs. 5-26 maintaining time reversal symmetry.

Building Competitive Direct Acoustics-to-Word Models for English Conversational Speech Recognition [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2017 Direct acoustics-to-word (A2W) models in the end-to-end paradigm have received increasing attention compared to conventional subword based automatic speech recognition models using phones, characters, or context-dependent hidden Markov model states. This

Three-Dimensional Sound Propagation in the South China Sea with the Presence of Seamount
Journal of Marine Science and Engineering, 2021 Seamounts have important effects on sound propagation in deep water. A sound propagation experiment was conducted in the South China Sea in 2016. The three-dimensional (3D) effects of a seamount on sound propagation are observed in different propagation ...

Pull-in control in microswitches using acoustic Casimir forces [PDF]
Euro Physics Letters vol. 84 (2008) 48002, 2008 In this paper we present a theoretical calculation of the acoustic Casimir pressure in a model micro system. Unlike the quantum case, the acoustic Casimir pressure can be made attractive or repulsive depending on the frequency bandwidth of the acoustic noise.
