Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with specific embodiment, specific implementation of the present invention is described in detail:
embodiment one:
Fig. 1 shows a kind of realization flow realizing the method for function of hearing aid on mobile terminals that first embodiment of the invention provides, and details are as follows:
S101, gathers external sound information.
First user gathers extraneous acoustic information by the intelligent mobile terminal carried with, concrete can open function of hearing aid by starting application program, after opening function of hearing aid, gather extraneous acoustic information by the microphone of intelligent mobile terminal.
S102, carries out noise reduction process to the external sound information collected.
After collecting extraneous acoustic information, the external sound information collected is processed, first necessary separating treatment is carried out to acoustic information, one's voice in speech information is isolated from the acoustic information collected, again isolated acoustic information is carried out noise reduction process afterwards, make it possible to filter out noise to the full extent, only retain the acoustic information of part of speaking.
S103, carries out automatic gain control to the acoustic information after noise reduction process, and exports the acoustic information after gain-adjusted according to the parameter pre-set.
Automatic gain control is carried out to the acoustic information after noise reduction process, pass through automatic gain control, sound decibel number user after regulating can clearly be heard, again the parameter that sound is arranged according to user is exported sound afterwards, the parameter that wherein user is arranged can comprise the parameters to sound timbre, also can comprise the parameters etc. to sound intensity.
The embodiment of the present invention by the way, a kind of method realizing function of hearing aid on mobile terminals, extraneous acoustic information is gathered by intelligent mobile terminal, and noise reduction process is carried out to the acoustic information collected, afterwards gain-adjusted is carried out to sound, at the custom parameter arranged according to user, sound is exported, by processing sound and exporting according to the setting of user, user can be met under quiet environment or environment noisy especially, catch other people one's voice in speech, arranged by these, intelligent movable mobile terminal is made to be provided with the function of hearing aids, user is helped to realize hearing aid.
embodiment two:
Fig. 2 shows a kind of realization flow realizing the method for function of hearing aid on mobile terminals that second embodiment of the invention provides, and details are as follows:
S201, gathers extraneous acoustic information of speaking.
First user is when needs realize hearing-aid function by intelligent mobile terminal, user opens the intelligent mobile terminal carried with and gathers extraneous acoustic information, concrete can open function of hearing aid by starting application program, extraneous acoustic information of speaking is gathered by the microphone of intelligent mobile terminal after opening function of hearing aid, certain user also can when conversing, open hearing-aid function, directly gather the sound of speaking when conversing in phone.
S202, gathers extraneous noise information.
While sound is spoken in collection, gather extraneous environmental noise information, when for call, then directly gather the noise information in the speech transmitted in telephone speech, when the noise information for just directly gathering when common hearing-aid function is opened in external environment.
S203 is that acoustic information carries out separating treatment according to the acoustic information collected to collecting.
According to collecting acoustic information, separating treatment is carried out to the acoustic information collected, concrete processing mode is exactly that the sound of voice information collected and noise acoustic information are carried out separating treatment, the noise collected in sound of voice information is separated, also can carry out separating treatment to the noise sound collected simultaneously, isolate the acoustic information in noise, will speak acoustic information and noise acoustic information are separated as far as possible.
