Method and system for realizing three-dimensional sound effects in virtual reality

Abstract

The present invention discloses a method and system for realizing a virtual reality three-dimensional sound effect. The method comprises: acquiring a deflection angle, relative to a vertical direction, of a head part of a user; determining whether the deflection angle, relative to the vertical direction, of the head part of the user is greater than a threshold value or not; if yes, updating relative position coordinates of the head part of the user in a virtual space according to the deflection angle, relative to the vertical direction, of the head part of the user, updating a head-related pulse response function according to an updating result, superimposing sounds by adopting the updated head-related pulse pulse response function, acquiring a first signal formed by superimposing, and outputting the first signal to an earphone of the user; and if no, superimposing the sounds by adopting the head-related pulse pulse response function, acquiring a second signal formed by superimposing, and outputting the second signal to the earphone of the user. By implementing embodiments of the present invention, the virtual reality three-dimensional sound effect is realized by simple head action control, thereby greatly improving an experience feeling of the user.

Description

technical field [0001] The invention relates to the technical field of virtual reality three-dimensional sound effects, in particular to a method and system for realizing virtual reality three-dimensional sound effects. Background technique [0002] The current common stereo playback technology, surround sound effect, is common in the audio system of commercial theaters and home theaters. Simply put, surround sound is to place sound emitting devices in different directions of people, so that the listener can distinguish sounds from all directions, and increase the three-dimensional and real sense of sound. Like surround sound, virtual three-dimensional sound effects also hope to improve the three-dimensionality of sound, but only need to use two sound sources, such as two sound units of headphones or two speakers. The virtual three-dimensional sound effect is to use the spatial positioning of human hearing to try to restore the positioning of sound in the natural environmen...

Problems solved by technology

[0003] But in many cases, when there is only a single sound source, people also want to experience the stereoscopic three-dimensional sound effect. At this time, it is often not satisfied; It is even more difficult; therefore, users urgently need a device that allows users to experience stereoscopic three-dimensional sound effects in the case of a single sound source or in the case of hearing impairment.
