Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The specific implementation of the present invention is described in detail below in conjunction with specific embodiment：
Embodiment one：
Fig. 1 shows a kind of method for realizing function of hearing aid on mobile terminals that first embodiment of the invention provides
Implementation process, details are as follows：
S101 acquires external sound information.
User, specifically can be by opening by the extraneous acoustic information of portable intelligent mobile terminal acquisition first
Dynamic application program opens function of hearing aid, is adopted by the microphone of intelligent mobile terminal after opening function of hearing aid
Collect extraneous acoustic information.
S102 carries out noise reduction process to collected external sound information.
After collecting extraneous acoustic information, collected external sound information is handled, first to sound
Information carries out necessary separating treatment, and one's voice in speech information is isolated from collected acoustic information, later again will separation
The acoustic information gone out carries out noise reduction process so that can filter out noise to the full extent, only retain the sound for part of speaking
Information.
S103 carries out automatic gain control to the acoustic information after noise reduction process, and according to pre-set parameter to increasing
Acoustic information after benefit is adjusted is exported.
Automatic gain control is carried out to the acoustic information after noise reduction process, passes through automatic gain control so that after adjusting
Sound decibel number user can clearly hear, be exported again to sound according to the parameter of user setting to sound later,
The parameter of middle user setting may include the arrange parameter to sound timbre, can also include the arrange parameter to sound intensity
Deng.
The embodiment of the present invention passes through intelligence by the above-mentioned means, a kind of method for realizing function of hearing aid on mobile terminals
The extraneous acoustic information of energy mobile terminal acquisition, and noise reduction process is carried out to collected acoustic information, sound is carried out later
Gain-adjusted exports sound according to the custom parameter of user setting, by sound carry out processing and according to
The setting at family is exported, and can be met user and be caught the sound that other people speak in quiet environment or under especially noisy environment
Sound passes through these settings so that intelligent movable mobile terminal is provided with the function of hearing aid, and user is helped to realize hearing aid.
Embodiment two：
Fig. 2 shows a kind of methods for realizing function of hearing aid on mobile terminals of second embodiment of the invention offer
Implementation process, details are as follows：
S201 acquires extraneous sound of speaking information.
For user first when needing to realize hearing-aid function by intelligent mobile terminal, user opens portable intelligent sliding
The extraneous acoustic information of dynamic terminal acquisition, specifically can open function of hearing aid by starting application program, open
Extraneous sound of speaking information is acquired by the microphone of intelligent mobile terminal after function of hearing aid, certain user can also
In call, sound of speaking when opening hearing-aid function, directly acquisition call in phone.
S202 acquires extraneous noise information.
While acquiring sound of speaking, extraneous environmental noise information is acquired, when for call, then directly acquires phone
Noise information in the speech transmitted in sound just directly acquires in external environment when being opened for common hearing-aid function
Noise information.
S203 is that acoustic information carries out separating treatment to collecting according to collected acoustic information.
Separating treatment is carried out to collected acoustic information according to acoustic information is collected, specific processing mode is exactly will
Collected sound of voice information and noise acoustic information carry out separating treatment, will collect the noise in sound of voice information point
It separates out and, while separating treatment can also be carried out to collected noise sound, isolate the acoustic information in noise, as possible will
Sound of speaking information and noise acoustic information separate.
S204 carries out noise reduction process according to the noise and sound of speaking isolated to collected acoustic information.
Noise reduction process is carried out to collected sound according to noise and sound of speaking is isolated, is said due to having isolated
Acoustic information and noise acoustic information are talked about, but individually lock out operation is difficult to accomplish to locate well to noise and sound of speaking
Reason is handled, and the sound adulterated mutually is inevitably also had in the sound isolated and is occurred, it is therefore desirable to be carried out to sound further
Noise reduction process, further to extract better acoustic information.
S205 carries out automatic gain control to the acoustic information after noise reduction process.
Automatic gain control is carried out to the acoustic information after noise reduction process, it, can be according to collecting when specific gain-adjusted
Sound in the ratio relation and sound of speaking of sound of speaking and noise and the decibels of noise sound is carried out it is different degrees of
Automatic gain control so that the acoustic information after gain-adjusted can reach preferable audio visual effect.
S206 carries out the acoustic information after gain-adjusted stable output according to pre-set parameter.
Stable output is carried out to the sound after gain-adjusted according to pre-set parameter, since the sound received is outstanding
It is in telephone relation due to signal etc., and sound will appear suddenly big or suddenly small problem, especially needed at this time to hear one
The sound of a stabilization exports, and can be carried out at a degree of sound amplification according to the setting of user to receiving sound at this time
Reason so that the sound of output can keep stable sound intensity, while can also carry out ambient sound to the sound of output and set
It sets, the ratio relation between sound and extraneous environmental noise is exported by setting so that the sound of output has one with environmental noise
Fixed proportionate relationship, such as when external environment is noisy, the sound amplification appropriate of output, so that user can catch sound
Sound, and the output of proper ratio is carried out to sound when external environmental sounds are smaller so that it is unlikely to influence very much other people greatly,
In for output sound and extraneous environmental noise between ratio relation can be by being set manually on intelligent mobile terminal
It sets, while the arrange parameter of different mode can also be obtained directly on Internet Server by intelligent mobile terminal, with side
Just user's quick obtaining is to corresponding arrange parameter.
The embodiment of the present invention passes through intelligence by the above-mentioned means, a kind of method for realizing function of hearing aid on mobile terminals
The extraneous acoustic information of energy mobile terminal acquisition, and noise reduction process is carried out to collected acoustic information, sound is carried out later
Gain-adjusted exports sound according to the custom parameter of user setting, by sound carry out processing and according to
The setting at family is exported, and can be met user and be caught the sound that other people speak in quiet environment or under especially noisy environment
Sound, by realizing the function of hearing aid on mobile terminals, it is also possible that intelligent movable mobile terminal is with common hearing aid
Function when can be used for be in noisy environment and quiet environment converse, while less influence other people, help user
Realize multi-functional hearing aid.
