The technical solutions of the present invention will be described in detail below with reference to the embodiments and the drawings.

Embodiment 1:

As shown in FIG. 1, the embodiment provides a noise processing method, which is applied to a mobile terminal, and the method includes:

Step S110: Acquiring environmental information; Here, the environment information is specifically an environment call information, that is, information about an environment in which the user is in a call when using the mobile terminal, and the environment call information includes current location information of the mobile terminal;

Step S120: Send the environmental information.

Step S130: Receive a noise index that is queried according to the environmental information.

Step S140: Determine whether the preset noise processing start condition is satisfied according to the noise index, and start noise processing when satisfied.

How to obtain the environmental information in the step S110 may be used but is not limited to the following:

The first method is to obtain the current location information of the mobile terminal from the Global Positioning System (GPS), and the method is simple to implement. Generally, the mobile terminal has a GPS module, so that the existing mobile terminal is used. Easy access to current location information.

Manner 2: Obtain current location information of the mobile terminal according to a network device, such as a base station, to which the current mobile terminal is connected. The network device is fixedly located in one place and can be used as a mark of a geographical location. The network device is preferably a base station; the base station is provided at a callable location of the mobile terminal, and the geographical location information of each base station is correspondingly recorded in the service network, so that the geographic location of the existing network device is skillfully utilized to implement the current location of the mobile terminal. Location information acquisition, with the advantages of wide coverage and easy implementation.

In the step S120, the environment information may be packaged into a request message, such as a call request message, and sent to a device for querying the noise index by using a data service such as a short message, such as a network server. In order to distinguish from other messages, a fixed identifier may be added to the request message to indicate that there is corresponding environment information, such as adding a "QDN" character to the message header.

In the step S130, the noise index indicates the magnitude of the noise.

The specific operation in the step S140 may be: the received noise index is not less than the preset noise index threshold, indicating that the current location environment noise is large, and the corresponding noise reduction function needs to be turned on. In specific During the operation, the preset noise processing start condition described in the step S140 may be that the noise index satisfies a preset function relationship, and may specifically be a logical judgment as described above, or may be a noise function as a variable input function relationship. Then, through logic judgment, decide whether to turn on noise processing. The functional relationship may be a functional relationship such as a coefficient operation of a noise index. The coefficient may be a correction factor designed according to the noise sensitivity of the mobile terminal.

The mobile terminal may be a mobile terminal device such as a mobile phone, a tablet computer, or a hearing aid provided with a communication function.

In summary, in this embodiment, the noise index is obtained from the network device based on the current location information of the mobile terminal, thereby automatically enabling the noise reduction processing function when the noise processing function needs to be turned on. Compared with the prior art, the user manually turns on, which is more convenient, and the automatic opening can improve the call quality or the listening quality in time and effectively, and avoids the user forgetting to turn on, resulting in poor call quality, poor listening quality, and interrupted call due to poor call quality. problem.

Embodiment 2:

As shown in FIG. 2, this embodiment provides a noise processing method, where the method includes: Step S210: Acquire environment information;

Here, the environment information includes current location information of the mobile terminal;

Step S220: Send the environmental information.

Step S230: Receive a noise index that is queried according to the environmental information.

Step S240: Determine whether the preset noise processing start condition is met according to the noise index. Step S250: When the determination result in step S240 is satisfied, start noise processing. Specifically, the step S250 includes at least the following two steps:

Step S251: query a preset mapping relationship table between the noise index and the noise reduction algorithm according to the noise index, and obtain a noise reduction algorithm;

Step S252: Perform noise processing according to the noise reduction algorithm.

The noise reduction algorithm may be spectral subtraction, linear filtering, wavelet transform, and subspace. Algorithms such as speech denoising. The preset mapping relationship table may be a one-to-one mapping relationship table between the noise index and the noise reduction algorithm, or a many-to-one mapping relationship table between the noise index and the noise reduction algorithm. When the multi-to-one mapping relationship table is used in this embodiment, the utility is more practical, and the complexity of the preset mapping relationship table on the mobile terminal side and the storage of data are reduced relative to the one-to-one mapping relationship table. the amount. The multi-to-one mapping relationship table may specifically be that the noise index falls within a certain value interval, and one of the algorithms is used. Specifically, if the value of the noise index falls within the interval greater than a and not less than b, spectrum subtraction is used. When the value of the noise index falls within the interval less than b and not greater than c, the linear filtering method is used. Due to different geographical locations, the ambient noise level varies. For noises of different sizes, only the appropriate noise algorithm can be used to obtain better noise processing. Therefore, various noise reduction algorithms are pre-set in the noise processing in the embodiment to distinguish the environmental noises in different situations, and further improve the noise reduction effect.

Embodiment 3:

Due to different geographical locations, the type of ambient noise is usually different. Specific construction sites, often accompanied by a variety of sharp metal percussion sounds, such as the vegetable market usually has very noisy vocals, sharp metal percussion and noisy vocals obviously have different frequencies and timbre sounds The parameters have different effects on the call or the listening. Therefore, the noise reduction algorithm needs to be selected for different types of noise to achieve a significant improvement in call quality.

Therefore, as a further improvement of the embodiment, as shown in FIG. 3, the method in the embodiment includes the following steps:

Step S310: Acquire environmental information.

Step S320: Send the environmental information.

Step S330: Receive a noise index that is queried according to the environmental information.

Step S340: determining whether the preset noise processing start condition is met according to the noise index; Step S350: If the start condition is met, determining whether the noise index is greater than a preset threshold Value,

Step S360: If the noise index is greater than the preset threshold, send a noise sample request message; Step S370: Receive a noise sample that is queried according to the environment information and the noise sample request message;

Step S380: Determine a noise reduction algorithm according to the noise sample and perform noise processing.

In this embodiment, if it is determined in the step S350 that the noise index is not greater than the preset threshold, the noise processing can be directly started. The step of starting the noise processing may be the step S250 in the second embodiment.

The noise information includes a noise index and a noise sample. The noise sample is a noise sample extracted from the actual environment, so that the noise type and the like can be truly reflected, so that the step S380 may include extracting noise that needs to be filtered or removed from the noise sample, and determining to remove the noise. The preferred algorithm is specifically an adaptive noise cancellation method, and noise processing is performed according to the determined preferred algorithm. The above method can further optimize the noise reduction effect.

Therefore, in the noise processing of the embodiment, a plurality of noise reduction algorithms are pre-set to distinguish the environmental noises in different situations, and the call quality is further improved.

Provided in the present embodiment is a method for automatically starting to acquire a noise sample based on a noise index to determine whether a noise sample needs to be acquired. In a specific practical application process, whether or not a noise sample is requested may be indicated according to a user. Specifically, the corresponding trigger control or menu is set on the requesting device for the user to select or set. Using the automatic request method based on the user indication or the above threshold judgment to determine whether to request the transmission of the noise sample, the data amount of the data interaction can be effectively reduced, and the communication congestion and the like are reduced.

The specific operation is that the user indication requesting the noise sample can be sent to the network device together with the environmental information, and the network device can return the noise index and the noise sample together, thereby reducing the number of messages sent or the number of circuit connections.

Embodiment 4: Based on the first embodiment, the second embodiment or the third embodiment, the present embodiment has further improved, as follows:

The environmental information also includes current time information. The time information described herein generally does not include the date of the call, but only the time point, specifically, such as 9:00 am or 9:15 am. At different times in the same place, the environmental noise will change. Therefore, this embodiment refers to the change of the ambient noise at different times in the same place, and selects the noise index, which further improves the accuracy of the noise processing judgment, thereby avoiding the environmental noise to the call. Or the problem of noise processing is turned on when the impact is small, thereby reducing the energy consumption of the mobile terminal. When the mobile terminal is a mobile communication terminal, such as a mobile phone, the time information is time information of the current call; when the mobile terminal is a hearing aid or an audio playback device, the time information is time information at the time of use.

Specifically, if the street, daytime, and late night are noisy, the noise processing is usually turned on during the day to improve the quality of the call, and the noise is not turned on in the middle of the night to save energy, especially in smart devices with high energy consumption. Among them, the effect is particularly obvious.

In the implementation process, there are various methods for expressing the current location information. In this embodiment, the method for marking the latitude and longitude is preferably used, such as a latitude of 21.4812170 degrees and a longitude of 109.1198990 degrees; the latitude and longitude is widely used, indicating uniqueness, thereby having identification. The advantages of sex and versatility.

In addition, the minimum unit of the current position information labeling can also be set, for example, the minimum unit is 0.000001 degrees; the determination of the positioning accuracy of the current position information can be realized by the determination of the minimum unit, and in the specific implementation process, it can be performed as needed Flexible settings, with the advantages of controllability and interactivity. In summary, the first to fourth embodiments of the present invention provide an automatic open noise processing method, which can perform noise processing on a call in time, thereby improving call quality, and since it is automatically turned on relative to manual startup in the prior art. , intelligent and higher, more convenient to use. Embodiment 5: This embodiment provides a noise processing method, which is applied to a network device. As shown in FIG. 4-1, the method includes:

Step S410: Receive environment information.

Step S420: Query a noise index corresponding to the environmental information in a pre-established noise information database;

Here, the noise index is used for determining whether the mobile terminal initiates noise processing; Step S430: transmitting the noise index.

Here, it is specifically used to send the noise index to a requesting device such as a mobile terminal.

The environment information in the step S410 is mainly sent by the mobile terminal, and includes at least the current location information of the mobile terminal.

In the database in step S420, at least the mapping relationship between the current location information and the noise information is established in advance, so that the corresponding noise index can be obtained according to the environment information. The noise index data may be data collected in the field or simulated data formed according to various simulations. Specifically, if the collection terminals are provided at the respective locations, the collection terminals return the collected data to the network side, and use the network side to form information records in which the position and the noise information are mapped. For example, the traffic flow and traffic flow at the street A are known through the transportation system, and the noise caused by the traffic flow and the traffic flow is obtained according to a certain data simulation model, and the corresponding noise index is obtained. Using the method of field collection, the data is more accurate. If you use simulation, it is easy to implement and low equipment cost. In the specific implementation process, the above two types may be combined as needed, but the above two types are not limited.

The environmental information may be packaged into a request message, and the noise index may be packaged into a reply message replied to the request message. In the header of the request message, a character such as "QDN" can be set to carry the environmental information, and a character such as "QDNA" which can be set at the head of the reply message indicates that the noise index is carried. There are a variety of specific implementation methods, and the information interaction can be performed by using data services such as short messages. In the noise processing method of the embodiment, by establishing the correspondence between the location information and the noise index in advance, the current location information is extracted from the environment information when the mobile terminal talks, so that the noise index can be sent to the mobile terminal, and then the mobile terminal according to the noise index It is judged whether the noise processing is turned on, and the implementation is simple, and the call quality of the mobile terminal is improved.

The environment information at different times in the same location, in order to provide more accurate noise information, in the embodiment, the environment information further includes time information corresponding to the current call of the mobile terminal, where the maximum accuracy of the time information is Hours, thereby forming a mapping relationship including position information, time information, and noise index in the noise information database to facilitate the query. Easy to ask.

In addition, the types of environmental noises at different locations are different. Only when different types of environmental noises are treated differently, a better noise treatment effect can be obtained. Therefore, in the embodiment, further improvement is made, and the noise information includes noise. Index and noise samples.

The noise index reflects the magnitude of the noise, and the noise sample includes a noise sample collected in the field, from which information such as noise to be removed can be obtained.

In the step S420, the noise index and the noise sample may be queried together according to the environmental information; and in the step S430, the noise index and the noise sample are sent to the requesting device, such as a mobile phone and a hearing aid device. in. However, in this embodiment, it is preferable to determine whether to transmit a noise sample according to a user indication or by a judgment in the requesting device, to reduce the amount of data to be transmitted, and to reduce communication congestion and the like.

The following specifically provides a preferred method: As shown in FIG. 4-2, after transmitting the noise index, the method further includes:

Step S440: Receive a noise sample request message;

Step S450: Query the noise sample according to the environmental information and the noise sample request message; Step S460: Send the noise sample.

The above method is to send a noise sample based on a request message sent by a requesting device, such as a mobile terminal, to effectively reduce the amount of interactive data, and is simple and practical.

The noise figure and the noise samples are all kinds of noise information stored in a noise information database. The noise sample can be used by the mobile terminal to extract the noise to be processed therefrom. In the specific operation, the requesting terminal may provide the current environment information, and the noise information corresponding to the current location information does not exist in the database, and the environment noise is similar to the current location area according to the preset rule. This returns the noise information of similar areas. The size of the similarity can be determined based on information such as application scenarios and geographical relationships.

Specifically, the preset rule is a minimum distance principle, and an area closest to the current position is selected, and noise information corresponding to the area is returned, so as to subsequently determine whether to start noise processing.

Of course, in the specific implementation process, it is not limited to the principle of minimum distance. In order to reduce the storage of the data, the merging of the regions may be implemented. The merged regions may be adjacent or non-contiguous regions, and the environmental noise similarity between the two regions may be less than the preset difference. Usually, the same application scenarios, such as the high degree of similarity between streets, such as stations; the same type of ambient noise in the application scenario area, the same trend of environmental noise, with great similarities, can form regional Consolidation, which in turn reduces the amount of data stored in the database. Of course, when collecting or calculating noise information, the similarity between the application scenario and the environmental noise trend can be reduced to reduce the amount of data collection and calculation, and simplify the formation of the database.

Similarly, when the above situation occurs, that is, when there is no record of the noise information corresponding to the current location information in the database, the server may further search according to the current location information on the platform such as the network, obtain the application scenario information of the current location, and then Apply the scenario information, select an area B that is the same application scene as the current location of the mobile terminal, and return the noise information of the area B. The precondition for using this method is that at least some areas of the pre-established noise information database are provided with application scene fields and corresponding records. In summary, the present embodiment provides a method for manually starting noise processing in the past, which can be started according to the current call environment, thereby reducing the impact of environmental noise on call quality in time, with high intelligence and good user experience. . Example 6:

The embodiment provides a noise processing method, as shown in FIG. 5, which is applied to a system composed of a mobile terminal and a network device, and the method includes:

Step S510: The mobile terminal acquires environment information.

The mobile terminal may be a mobile station or a mobile station.

Step S520: The mobile terminal sends the environment information to a network device.

Step S530: The network device receives the environment information.

Step S540: The network device queries a noise index corresponding to the environmental information in a pre-established noise information database.

Step S550: The network device sends the noise index to the mobile terminal. Step S560: The mobile terminal receives the noise index.

Step S570: The mobile terminal determines whether the preset noise processing start condition is satisfied according to the noise index, and starts noise processing when satisfied.

The environment information may include only current location information, and may also include current location information and time information of the call. In addition, the network device is further configured to send a noise sample corresponding to the current location information according to the request message sent by the mobile terminal. The noise sample and the noise index provide a basis for the mobile terminal to determine a noise reduction algorithm.

In this embodiment, the noise index corresponding to the current environment is confirmed based on the interaction between the mobile terminal and the network device, and the mobile terminal can automatically turn on the noise processing when the noise index meets the preset noise starting condition, and timely perform noise processing. Improve the quality of the call or listening, and automatically turn on the noise processing is easy to use. Example 7:
