Acoustic Virtual Training for the Blind
Acoustic Ecology Review, 2023Individuals 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, 2008Acoustic 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, 2022Recent 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, 1992This 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.

2013
The technology for creating an Acoustic Virtual Reality for wide variety of applications has been developed in the last decade. An important requirement of Virtual Reality is the multimodal approach which includes vision, sound, tactile and haptic stimuli. The process of creating a physical stimulus based on computer data is called “rendering”.

Efficient acoustic perception for virtual AI agents
Proceedings of the ACM on Computer Graphics and Interactive Techniques, 2021We model acoustic perception in AI agents efficiently within complex scenes with many sound events. The key idea is to employ perceptual parameters that capture how each sound event propagates through the scene to the agent's location. This naturally conforms virtual perception to human.

The Journal of the Acoustical Society of America, 2003
In this paper the re-creation of 3-D sound fields so the full psycho-acoustic impact of sound sources can be assessed before the manufacture of a product or environment is examined. Using head related transfer functions (HRTFs) coupled with a head tracked set of headphones the sound field at the left and right ears of a listener can be re-created for a

A Method for Virtual Acoustic Auralisation in VR
Proceedings of the Audio Mostly 2018 on Sound in Immersion and Emotion, 2018In today's industry, the use of prediction software in architectural acoustics is universal. Programs such as Odeon, CATT and CadnaA have become an integral part of the design process. These programs combine general acoustic theory with CAD modelling software to calculate the trajectory and intensity of sound waves as they travel around the room.

Peripheral Sonification by Means of Virtual Room Acoustics
Computer Music Journal, 2020Abstract Peripheral interaction is a new approach to conveying information at the periphery of human attention in which sound is so far largely underrepresented. We report on two experiments that explore the concept of sonifying information by adding virtual reverberation to real-world room acoustics. First, to establish proof of concept,
