Problems solved by technology

[0005] When the related technology reduces noise, it is necessary to set the collection range of the microphone to collect the sound. However, when the volume of the noise within the set collection sound range is large, the related technology will still collect the noise, causing the related technology to reduce the noise. less effective when

Embodiment 1

[0046] In order to improve the communication quality when using communication equipment for communication and reduce noise interference during communication, an embodiment of the present invention provides a method for reducing noise, see figure 1 , the method flow provided by this embodiment includes:

[0047] 101: Synchronously collect the current environmental sound with the first terminal to obtain the first environmental sound, and obtain the environmental sound collected by the first terminal to obtain the second environmental sound, where the environmental sound includes user voice and noise.

[0048] As an optional embodiment, synchronously collecting the current ambient sound with the first terminal includes:

[0049] Determining a delay time for synchronously collecting the current environmental sound with the first terminal, obtaining time stamp information, and collecting the current environmental sound according to the time stamp information.

[0050] As an optio...

Embodiment 2

[0061] The embodiment of the present invention provides a method for reducing noise. In order to facilitate understanding, the method for reducing noise provided by the embodiment of the present invention is described in detail in combination with the content of the first embodiment above, taking the noise reducing device as a mobile terminal as an example. Explanation, see figure 2 , the method flow provided by this embodiment includes:

[0062] 201: Synchronously collect the current environmental sound with the first terminal to obtain the first environmental sound.

[0063] Wherein, the environmental sound includes but not limited to the user's voice and noise, etc., and this embodiment does not specifically limit the environmental sound. The first terminal is a Bluetooth headset or the like, and this embodiment does not specifically limit the first terminal. Because in the scenario of communicating with the first terminal, not only the sound collection device in the mob...

Embodiment 3

[0104] see image 3 , an embodiment of the present invention provides a device for reducing noise, the device comprising:

[0105] The collection module 301 is configured to collect the current environmental sound synchronously with the first terminal to obtain the first environmental sound;

[0106] The first acquiring module 302 is configured to acquire the environmental sound collected by the first terminal to obtain the second environmental sound, where the environmental sound includes user voice and noise;

[0107] An extraction module 303, configured to extract the user's voice in the first environmental sound and the user's voice in the second environmental sound;

[0108] The second acquiring module 304 is configured to acquire a pure user voice according to the extracted user voice in the first ambient sound and the extracted user voice in the second ambient sound.

[0109] see Figure 4 , the acquisition module 301, comprising:

[0110] A determining unit 3011, c...

Abstract

The present invention discloses a method and an apparatus for reducing noises, belonging to the field of wireless communication technique. The method includes the steps as follows: collecting current environment sounds by synchronizing with a first terminal to obtain first environment sounds, and acquiring environment sounds collected by the first terminal to obtain second environment sounds, wherein, the environment sounds include a user sound and a noise; extracting the user sound from the first environment sounds and the second environment sounds; and acquiring a pure user sound according to the user sound extracted from the first environment sounds and the second environment sounds. According to the invention, the second environment sounds collected by the first terminal are acquired by the collection of the first environment sounds synchronized with the first terminal, then the user sounds of the first environment sounds and the second environment sounds are extracted, and the pure user sounds are acquired from the user sounds extracted from the first environment sounds and the second environment sounds. The method and the apparatus can efficiently reduce noises because the acquired user sounds are pure user sounds.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for reducing noise. Background technique [0002] With the development of wireless communication technology, more and more communication devices based on wireless communication technology gradually enter people's lives, for example, mobile phones, bluetooth earphones and the like. When these communication devices are used for communication, these communication devices can not only collect the voice of the user, but also collect the surrounding environmental noise. Since the collected environmental noise has an impact on the communication quality of the communication device, in order to improve the communication quality of the communication device Communication quality, how to reduce noise, has become a problem that those skilled in the art pay more attention to. [0003] In the related art, when reducing noise, the purpose of noise reduction is...
