Historical Acoustics: Relationships between People and Sound over Time
The Special Issue “Historical Acoustics: Relationships between People and Sound over Time” was the inaugural collection of the recently established journal “Acoustics (MDPI)”, so it felt appropriate to give it a focus to history ...

Acousto-elastic interaction in combustion chambers [PDF]
This thesis deals with the interaction between combustion, acoustics and vibrations with emphasis on frequencies below 500 Hz. Extensive literature is available on the interaction between combustion and acoustics and much work is also available on the ...

Broadband Acoustic Collimation and Focusing using Reduced Aberration Acoustic Luneburg Lens [PDF]
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 ...

Research on the Robustness of Active Headrest with Virtual Microphones to Human Head Rotation
The movement and rotation of the human head can significantly degrade the control performance of active headrests with virtual microphones. This paper investigates the performance robustness of an active headrest with virtual microphones against the head

Some information on acoustic topological insulator [PDF]
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.

Investigating the Potential Use of EEG for the Objective Measurement of Auditory Presence
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.
