Auditory Virtual Environment (AVE)
An auditory virtual environment (AVE) is a virtual environment (VE) that focuses on the auditory domain only.
An auditory virtual environment (AVE) is a virtual environment (VE) that focuses on the auditory domain only. It sees itself independent form other modalities like vision and tactility. Nevertheless an AVE could also be combined with the visual and haptic domain. Depending on the application, the user may be only a passive receiver or even be able to interact with the environment.
There are three different approaches for implementations of AVEs:
1 - Authentic reproduction of real existing environments.
The
virtual room should evoke in the listener the same percepts that would
have been evoked by the corresponding real environment. He should have
same spatial impression moving through and perceive his own movement
inside the environment as well as the movements of sound sources.
2 - Reproduction of plausible auditory events
This
approach tries to evoke auditory events which the listener perceives as
having occurred in a real environment. Here only those features are
implemented which are needed for a specific simulation situation.
3 - Creation of non-authentic and non-plausible auditory events or environments.
The virtual room doesn't evoke percepts in the listener which are related to a real acoustic environment.
