VIRTUAL WORK EXPERIENCE IN ACOUSTICS

Inter-Noise 2022, 2023
The Institute of Acoustics is in the process of organising a virtual work experience for up to 1000 GCSE and A-Level students. Unlike traditional workplace work experience, the virtual environment will provide an overview of the acoustics industry, an opportunity to engage with a large number of students from anywhere in the UK and a window to show ...

Assessing the Plausibility of Virtual Acoustic Environments

Acta Acustica united with Acustica, 2012
Aiming at the perceptual evaluation of virtual acoustic environments (VAEs), 'plausibility' is introduced as a quality criterion that can be of value for many applications in virtual acoustics. We suggest a definition as well as an experimental operationalization for plausibility, referring to the perceived agreement with the listener's expectation ...

Acoustic virtual mass of granular media

The Journal of the Acoustical Society of America, 2007
Mechanical coupling between grains in a randomly packed unconsolidated granular medium is shown to cause an increase in the effective inertia, hence, a reduction in sound and shear wave speeds, relative to predictions by the standard expressions for a uniform elastic solid.

Acoustic Virtual Training for the Blind

Acoustic Ecology Review, 2023
Individuals who are blind or visually impaired learn to rely on their sense of hearing to compensate for their lack of vision.Learn- ing to“see” using the ears is difficult, and requires considerable time and experience. Fortunately, training programs for the blind, referred to as Orientation and Mobility (OM), have been widely implemented at ...

Diffraction Culling for Virtual-Acoustic Simulations

Acta Acustica united with Acustica, 2008
Acoustic simulations of complex virtual environments typically are created with geometrical-acoustics techniques. Such simulations can be augmented with edge diffraction modeling for improved accuracy, but not without a significant increase in processing time due to the additional propagation paths which must be considered and the computational ...

How real is Virtual Acoustics?

The Journal of the Acoustical Society of America, 2022
Recent comparisons of room-acoustic simulations and auralizations demonstrated that a high degree of realism can be achieved under certain conditions. How close the simulation can get to reality depends on the definition of the objective in general terms (authenticity or plausibility).

Localization in Virtual Acoustic Displays

Presence: Teleoperators and Virtual Environments, 1992
This paper discusses the development of a particular spatial display medium, the virtual acoustic display. Although the technology can stand alone, it is envisioned ultimately to be a component of a larger multisensory environment and will no doubt find its greatest utility in that context.
