Description
Technical field
The present invention relates to a kind of sound processing method more particularly to a kind of sound processing methods of artificial cochlea.
Background technique
Artificial cochlea is common bio-medical engineering equipment at present, serve mainly to facilitate hearing aids effect it is bad or
The absolutely void severe of person, pole severe deafness patient.Artificial cochlea is divided into the implant to implant and wears in external body
Two parts of outer machine, the encoded information of certain coding form is converted sound by external machine, straight by the electrode to implant
Excited auditory nerve is connect to restore, improve and rebuild the auditory function of deaf person.In vitro during the acoustic processing of machine, sound is located in advance
The quality of reason directly determines that wearer's listens acoustic mass, so, researching and developing and optimizing higher-quality sound preprocess method is
Where the center of gravity of now most artificial cochlea companies, but the volume for being limited by external machine is all smaller, and battery can not be done greatly,
High performance processing chip can not be used, which results in present sound pretreatment research and development and optimization to enter a bottleneck period.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of artificial cochlea's
Sound processing method is collected and is pre-processed to sound by intelligent terminal.
To achieve the above object, the present invention provides the sound processing methods of artificial cochlea a kind of comprising following steps:
(a) intelligent terminal collects sound by microphone；
(b) intelligent terminal pre-processes the sound of collection；
(c) pretreated voice signal is sent to external machine by the wireless communication module of itself by the intelligent terminal
Nothing
Line communication module；
(d) received pretreated voice signal is sent to dsp chip again by the wireless communication module of the external machine；
(e) pretreated voice signal is converted into artificial cochlea electrode encoded information by the dsp chip.
The intelligent terminal includes smart phone, tablet computer.Further, which is equipped with more than two Mikes
Wind.
In step (b), which includes noise reduction, echo cancellor, noise scenarios identification.Further, the intelligence is whole
End pre-processes sound by way of installation APP or installation audio processing modules.
In step (c), which sends pretreated voice signal by bluetooth or WLAN.
The sound processing method of artificial cochlea of the present invention is collected and is pre-processed to sound by intelligent terminal, is improved
The pretreated efficiency of sound, and constraint that also need not again by power consumption and operational performance when researching and developing sound Preprocessing Algorithm,
The use duration of external machine is extended simultaneously.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
Detailed description of the invention
Fig. 1 is the flow chart of the sound processing method of artificial cochlea.
Fig. 2 is the module operation workflow figure of the sound processing method of artificial cochlea.
Specific embodiment
The invention will be further elaborated with reference to the accompanying drawing.
As shown in Figures 1 and 2, the present invention provides the sound processing methods of artificial cochlea a kind of comprising intelligent terminal
Sound, intelligent terminal pre-processing sound are collected, voice signal is wirelessly transferred, is transmitted to DSP (Digital Signal Processing) chip and sound
Sound signal is converted to five steps of encoded information, specific as follows:
1, intelligent terminal collects sound: intelligent terminal collects sound by microphone, wherein the intelligent terminal includes intelligence
Mobile phone, tablet computer；
2, intelligent terminal pre-processing sound: the intelligent terminal pre-processes the sound of collection, wherein the pretreatment packet
Include noise reduction, echo cancellor, noise scenarios identification；
3, be wirelessly transferred voice signal: the intelligent terminal is believed pretreated sound by the wireless communication module of itself
Number it is sent to the wireless communication module of external machine, wherein the intelligent terminal sends pretreated sound by bluetooth or WLAN
Signal；
4, be transmitted to dsp chip: the wireless communication module of the external machine again sends out received pretreated voice signal
It send to dsp chip；
5, voice signal is converted to encoded information: pretreated voice signal is converted into artificial cochlea by the dsp chip
Electrode encoded information exports stimulus information to corresponding electrode by transmitting coil.
When the intelligent terminal is equipped with more than two microphones, noise reduction of microphone array theory can be efficiently used, is mentioned
Rise noise reduction effect.
The intelligent terminal possesses the battery of larger capacity and the processing chip of superior performance, so energy relative to external machine
The pretreated efficiency of sound is greatly improved, and also need not be again by power consumption and operational performance when researching and developing sound Preprocessing Algorithm
Constraint, for research and develop more preferably algorithm provide hardware foundation.Simultaneously as the external machine reduces the collection of sound and locates in advance
Reason process, reduces energy consumption, extends the use duration of external machine, and the intelligent terminal is due to facilitating charging or replacement battery,
Therefore it need not be by the constraint of electricity.
The intelligent terminal can pre-process sound by way of installing specific APP or installation audio processing modules,
It, can be by way of updating software, so that wearer timely uses newest calculation when being pre-processed by the specific APP
Method improves usage experience.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be within the scope of protection determined by the claims.
