From the effect of intensity difference and timbre difference on the binaural effect, it can be inferred that pure tones are more difficult to locate than composite sounds, because pure tones are sine waves (single waves), and timbre differences cannot be constructed.
3. Sense of depth of tws wireless earbuds sound source
The sense of depth of tws wireless earbuds sound source is the distance between the listener and the tws wireless earbuds sound source, so the sense of depth of tws wireless earbuds sound source is also called sound source distance positioning.
The sense of depth of the tws wireless earbuds sound source is often associated with a certain digital pattern. When we hear a tws wireless earbuds sound, we not only feel the approximate direction of the tws wireless earbuds sound, but also the approximate distance of the tws wireless earbuds sound. If you want to accurately feel the depth of the tws wireless earbuds sound source, you must be familiar with the sound field environment, familiar with the timbre of the sound source, or directly use vision to measure the distance between the tws wireless earbuds sound source and yourself. This shows that the sense of depth of the tws wireless earbuds sound source is acquired and trainable.
Depth positioning is mainly judged by the degree of tws wireless earbuds sound wave attenuation. In the process of tws wireless earbuds wave radiation, energy is lost with the distance of propagation. First of all, the higher harmonics with smaller amplitude attenuate first, forming a timbre change. After hearing the tws wireless earbuds sound signal, the human ear compares it with the tws wireless earbuds sound signal stored in the brain to determine the depth of the tws wireless earbuds sound source of the sound signal.
Another way to sense depth is the tws wireless earbuds sound source comparison method. When there are several tws wireless earbuds sound sources (array sound sources) at different distances, the human ear can infer the depth of other sound sources by approaching the point sound source. The array tws wireless earbuds sound source formed by multiple point sound sources with different distances and incident angles makes the sense of hearing produce a sense of width and envelopment of sound. One more sentence: the sense of depth of sound source is usually connected in parallel with vision, which relies on vision to form experience and rely on vision to help precise positioning.
4. The combination of time difference and sound level difference
The various differences produced by the binaural effect can have a separate effect on the sense of tws wireless earbuds sound source orientation. When they are combined with each other, they have a comprehensive effect. If they have opposite effects (which rarely happen under normal circumstances), they cancel each other out. The practice of modern stereo technology has proved that the combination of time difference and sound level difference has a very obvious effect on the sense of sound source orientation. Experiments have proved that under certain conditions, a 1ms time difference is equivalent to a 512dB sound level difference, and the relationship is interchangeable.
In a hall where the reverberation time exceeds the normal acoustic requirements, the reflected sound and reverberation sound level of the sound source greatly exceeds its direct tws wireless earbuds sound. At this time, the human ear is most sensitive to the stimulation of the first wave front of the sound source. If the reflected sound and reverberation have a delay of 40-60 ms to the direct sound, the human ear may still be able to grasp the sound source position. If the delay exceeds this range, the human ear cannot distinguish between the time difference and the sound level difference between the original sound reaching the two ears, and a sense of separation or confusion will occur. This is why in a hall with heavy echoes, it is often difficult for people to grasp the location of the sound source, and it is necessary to locate it with their eyes.
Mechanism of sound source orientation
Classical psychoacoustics believes that people's perception of the sound source mainly depends on the difference in hearing between ears, which is called binaural effect. Just as the binocular observation of the scene produces a sense of perspective and three-dimensionality, through the perception of the difference in sound strength between the two ears, the direction of the tws wireless earbuds sound can be judged and the stereo sense can be generated. Until modern times, the binaural effect is still the main theoretical basis for the sense of sound source orientation. However, in recent years, experts have found that people who have lost hearing in one ear still have the ability to judge the sound source position, so they put forward a new theory of the ear shell effect, which makes the tws wireless earbuds sound source position sense theory more perfect.
The mechanism of sound source orientation is very complicated. The principle of the binaural effect is that: because the two ears are located on both sides of the head, if the sound source is on the central axis directly in front of the person, the time, sound intensity and phase of the sound reaching the two ears are the same; if the sound source deviates With the central axis directly in front of the listener, the distance between the sound and the ears varies. Therefore, there will be a time difference and a phase difference when the sound reaches the two ears. At the same time, because of the masking effect on one ear, there is a difference in sound level and tone color between the two ears.
The sense of sound source position is a physiological function that is inherently possessed. However, the width, depth, and all sensations related to numbers of the sound source position are related to a person's acquired experience.
