Embodiment 1

[0047] In the step 3 of the present embodiment, the mode of adjusting the sound volume of the left and right channels is adopted to adjust the sound, and this embodiment specifically includes the following steps:

[0048] Step 1, such as figure 1 As shown, the system establishes a polar coordinate system with the current position of the user's head at 6 as the pole and the current direction of the user's head at 10 as the polar axis, and sets the initial angle of angular velocity data integration to 0 degrees.

[0049]Step 2, select an angle arbitrarily within the range 3 of 0° to 180° and the range 7 of 0° to minus 180° of the polar coordinate system as the target angle 9 that the user needs to identify, for example, the target angle 9 is 40°, and the position of the sound source 1 is the position of the sound source imagined in the user's brain in the polar coordinate system.

[0050] Step 3, if the user turns the head to position 4 at this time, then the front direction of...

Embodiment 2

[0054] In step 3 of this embodiment, the sound played in the earphone needs to be recorded and obtained in advance. The recording method is: fix a stereo microphone at the same position, take the position of the stereo microphone as the center of the circle, and set up a circle with a radius of 3 meters. The front direction of the stereo microphone is 0 degrees, within the angle range of 0 degrees to 180 degrees and 0 degrees to minus 180 degrees on the circumference, move the sound source every 1 degree, and use the stereo microphone to record the sound source at different positions Audio signal, the sound source audio signal adopts a sine wave signal with a frequency of 1500 Hz. This embodiment specifically comprises the following steps:

[0055] Step 1, such as figure 1 As shown, the system establishes a polar coordinate system with the current position of the user's head at 6 as the pole and the current direction of the user's head at 10 as the polar axis, and sets the in...

Abstract

The present invention proposes a method and device for listening to sound, belonging to the technical field of sound processing and human-computer interaction, including: 1. Establishing a polar coordinate system; 2. Selecting the target angle; 3. Collecting the angular velocity of the earphone in real time through an angular velocity sensor Data, integrate the angular velocity data to calculate the user's current angle, calculate the angle difference between the target angle and the user's current angle, and adjust the sound played in the earphone according to the angle difference; 4. Calculate the score of the user's orientation judgment accuracy. This method makes full use of the human auditory system's ability to perceive spatial positions, provides a method for users to judge the direction of sound sources through sound, and quantifies the user's ability to distinguish sound through scoring, which is helpful for users Participants continuously improve the ability of spatial position perception during practice. This method can be used as a means for game developers to develop auditory games.

Description

technical field [0001] The invention belongs to the technical field of sound processing and human-computer interaction, and in particular relates to a method and device for position identification by listening. Background technique [0002] The human auditory system is very magical. Under the action of the brain, people can distinguish the direction of the sound source very well. When people close their eyes and concentrate on listening, the ability to distinguish the location of the sound will be more powerful. Therefore, if this ability can be practiced continuously, it will help to give full play to the human brain's perception of spatial information. potential. [0003] At present, various mobile games and computer games are flooding people's lives, and almost all games have both visual and auditory elements, but game developers often only focus on visual experience and interactivity, and hearing is only used as rendering Auxiliary means of game atmosphere. If the spa...
