Perceptual-based 3D sound localization : ウィキペディア英語版 | Perceptual-based 3D sound localization
Perceptual-based 3D sound localization is the application of knowledge of the human auditory system to develop 3D sound localization technology. == Motivation and Applications == Human listeners combine information from two ears to localize and separate sound sources originating in different locations in a process called binaural hearing. The powerful signal processing methods found in the neural systems and brains of humans and other animals are flexible, environmentally adaptable, and take place rapidly and seemingly without effort. Emulating the mechanisms of binaural hearing can improve recognition accuracy and signal separation in DSP algorithms, especially in noisy environments. Furthermore, by understanding and exploiting biological mechanisms of sound localization, virtual sound scenes may be rendered with more perceptually relevant methods, allowing listeners to accurately perceive the locations of auditory events. One way to obtain the perceptual-based sound localization is from the sparse approximations of the anthropometric features.Perceptual-based sound localization may be used to enhance and supplement robotic navigation and environment recognition capability.〔In addition, it is also used to create virtual auditory spaces which is widely implemented in hearing aids.
