Description

Technical Field

[0001] The present application relates to the field of Bluetooth headsets, and more specifically to an NFC Bluetooth headset control system, method, and storage medium. Background Art

[0002] Bluetooth noise-cancelling headphones mainly achieve noise reduction through two technologies: Active noise reduction: Microphone pickup: There is a microphone inside or outside the headset to capture the noise in the environment in real time, Anti-phase sound waves: The processing chip in the headset analyzes these noise signals and then generates sound waves opposite to the noise (ie "anti-phase sound waves"), Noise cancellation: These anti-phase sound waves are played through the headphone speakers, meet the ambient noise and cancel each other out, thereby reducing the input of noise. Active noise reduction technology is particularly effective for continuous low-frequency noise (such as airplane and train engine sounds), Passive noise reduction: Physical sound isolation: Through the materials and design of the earmuffs or earplugs, physically Block and absorb external noise. Designs such as high-density foam, silicone earplugs and closed earmuffs help reduce the input of external sounds and isolate high-frequency noise: Passive noise reduction is usually more effective for high-frequency noise (such as human voices and keyboard tapping sounds), but when using active noise reduction, it is impossible to remove sounds similar to those in the headphones, such as human voices. This makes it inconvenient to use in crowded places such as subways. For passive noise reduction, additional sound insulation components are required, resulting in a larger volume, which is also not suitable for use in crowded places. At this time, a headset that can automatically adjust the volume according to changes in external noise is needed to meet the needs of use;

[0003] When the existing technology automatically adjusts the volume according to the change of external noise, most of them only adjust the volume according to the size and noise of the external noise, without considering the different effects of similar sounds and different sounds in the earphone on hearing (such as the effects of air conditioning noise and human voice noise), resulting in poor adjustment quality. Most of the existing technologies have the above problems;

[0004] In order to solve the problems raised by this background technology, the present application designs an NFC Bluetooth headset control system, method and storage medium. Summary of the invention

The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0041] Example 1

[0042] In order to solve the technical problems raised in the background technology, the present application provides a preferred embodiment: Figure 1-Figure 3 As shown, a NFC Bluetooth headset control method includes the following specific steps:

[0043] Step 1, obtaining characteristic information of the external scene sound of the Bluetooth headset and characteristic information of the sound being played by the Bluetooth headset;

[0044] In a specific embodiment, the specific content of obtaining the characteristic information of the external scene sound of the Bluetooth headset and the characteristic information of the sound being played by the Bluetooth headset is:

[0045] Step 11, at the signal collection end of the headset, feature information of the external scene sound is collected through the sound collection module, wherein the feature information of the external scene sound includes the frequency of the external scene sound, and the frequency of the external scene sound is decomposed into the sound spectra of different subjects in the scene through the sound processing software. It needs to be specifically explained that, for example, the sound of the subway operation, the track sound and the sound of the people talking in the subway are separated into the sound spectrum of the subway operation in the subway, the track sound spectrum and the sound spectrum of the people talking in the subway.

[0047] Step 13: simultaneously obtain the sound frequency of the sound being played by the Bluetooth headset, the standard loudness of the Bluetooth headset, and the safe loudness range information. It should be specifically noted that the standard loudness of this embodiment is the loudness corresponding to the most appropriate volume selected by the user, and the safe loudness range is the loudness range corresponding to the volume that does not have a negative impact on the user's ears;

[0048] Step 2: Acquire feature information of external similar sounds based on feature information of the sound being played by the Bluetooth headset and feature information of the sound of the external scene of the Bluetooth headset;

[0049] In a specific embodiment, obtaining feature information of external similar sounds based on feature information of the sound being played by the Bluetooth headset and feature information of scene sounds outside the Bluetooth headset includes the following specific steps:

[0050] Step 21, obtaining the sound frequency of the sound being played by the Bluetooth headset and the sound frequency of the sound emitted by different subjects in the scene that can be heard by the ear;

[0051] Step 22: The sound frequency of the sound being played and the sound frequencies of the sounds emitted by different subjects in the scene that can be heard by the ear are introduced into a sound similarity calculation formula to calculate the sound similarity, wherein the sound similarity calculation formula is: , where mz is the similarity between the sound of the zth subject and the sound being played, T is the acquisition time, xtz is the sound frequency of the sound of the zth subject at time t, xtm is the sound frequency being played at time t, and dt is the time integral. It should be specifically noted that the purpose of this setting in this embodiment is that the more similar the sound frequencies of the sounds within a certain period are, the higher the similarity of the two sounds is;

[0052] Step 23: select a sound type whose sound similarity is greater than or equal to a set sound similarity threshold as an external similar sound. It should be specifically noted that in this embodiment, similar sounds whose interference degree with the sound being played is high are obtained;

[0053] Step 3: Perform similar sound interference assessment based on feature information of similar external sounds and feature information of the sound being played by the Bluetooth headset;

[0054] In a specific embodiment, performing similar sound interference assessment based on feature information of external similar sounds and feature information of sounds being played by the Bluetooth headset includes the following specific steps:

[0055] Step 31, obtaining the sound similarity of external similar sounds and the loudness information of the corresponding external similar sounds;

[0056] Step 32: Import the sound similarity of the external similar sound and the loudness information of the corresponding external similar sound into a similar sound interference value evaluation formula to evaluate the similar sound interference value, wherein the similar sound interference value evaluation formula is: , where N is the number of similar external sounds, mj is the sound similarity of the j-th similar external sound, exp() is the power of the natural constant e, cj is the average loudness of the j-th similar external sound, cm is the loudness of the sound being played by the Bluetooth headset, and it should be specifically noted that this embodiment evaluates the interference of similar sounds on the headset sound based on the similarity of similar sounds and the loudness of similar sounds, where N is the number of similar external sounds, mj is the sound similarity of the j-th similar external sound, exp() is the power of the natural constant e, cj is the average loudness of the j-th similar external sound, cm is the loudness of the sound being played by the Bluetooth headset, and it should be specifically noted that this embodiment evaluates the interference of similar sounds on the headset sound based on the similarity of similar sounds and the loudness of similar sounds;

[0057] Step 4: Evaluate the noisy scene sound based on the characteristic information of the external scene sound of the Bluetooth headset;

[0058] In a specific embodiment, the scene sound noisiness assessment based on the characteristic information of the external scene sound of the Bluetooth headset includes the following specific contents: Figure 3 As shown, Figure 3 This is a flow chart of step 4 of an NFC Bluetooth headset control method of the present application, wherein step 41, the sound frequency and loudness information of the sounds emitted by different subjects in the scene that can be heard by the ear, the sound frequency of the sounds emitted by different subjects in the scene that can be heard by the ear is introduced into the frequency noise value calculation formula to calculate the frequency noise value. It should be specifically noted that the frequency noise value calculation formula in this embodiment can be any formula such as variance and standard deviation that can evaluate the uneven sound frequency. For example, the frequency noise value calculation formula can be: , where n is the sound type, hi is the frequency of the i-th sound type, and hm is the average frequency of the sound type;

[0059] Step 42: Similarly, the loudness of the sounds emitted by different subjects in the scene that can be heard by the ear is introduced into the loudness-noise value calculation formula to calculate the loudness-noise value. It should be specifically noted that the loudness-noise value calculation formula in this embodiment can be any formula such as variance and standard deviation that can evaluate the uneven loudness of sounds. For example, the loudness-noise value calculation formula can be: , where n is the sound type, xi is the loudness of the i-th sound type, and xm is the average loudness of the sound type;

[0060] Step 43: Obtain the calculated frequency noise value and loudness noise value, perform weighted addition on them respectively, and obtain the sound noise value. It should be specifically noted that the weighted addition in this embodiment is as follows: the frequency noise value is multiplied by the frequency noise weight to obtain the frequency noise coefficient, the loudness noise value is multiplied by the loudness noise weight to obtain the loudness noise coefficient, and the frequency noise coefficient and the loudness noise coefficient are added to obtain the sound noise value;

[0064] It should be specifically noted that the value-taking method of the setting parameters in the present embodiment is obtained by technical personnel in this field through experiments. For example, the value-taking method of the setting parameters in the present embodiment (such as the weight of the proportion of similar sound interference values, the set interference standard value, the frequency noise weight and the loudness noise weight) is as follows: obtain the characteristic information of at least 500 groups of external scene sounds of the Bluetooth headset and the characteristic information of the sounds being played by the Bluetooth headset as experimental groups, substitute the experimental groups into the appropriate volume calculation formula to calculate the appropriate volume, obtain the expert's judgment results on the appropriate volume for these scenes, import the calculated appropriate volume and the artificial appropriate volume judgment results into the fitting software, and output the value of the setting parameters (such as the weight of the proportion of similar sound interference values, the set interference standard value, the frequency noise weight and the loudness noise weight) that meet the maximum judgment accuracy.

[0065] Step 6: Adjust the volume of the earphone to an appropriate volume. It should be specifically noted that how to adjust the volume of the earphone in this embodiment can be achieved by an ordinary volume adjustment controller. This is a conventional technical means for adjusting the volume in this field and will not be described in detail here. For example, if the appropriate volume is 50 decibels, the controller only needs to automatically adjust the earphone volume to 50 decibels.

This application takes into account the different effects of similar sounds and different sounds in the headset on hearing, and comprehensively evaluates the signal characteristics of similar sounds and the scene sound noisy characteristics to automatically obtain the appropriate playback volume, thereby improving the accuracy and safety of volume adjustment. For example, after exiting a noisy subway entrance, the playback volume of the headset is automatically lowered as the noise decreases.
