With reference to Fig. 1, it is shown that the flow chart of the method for the protection human ear audition of one embodiment of the invention, the method is applied
In mobile terminal, described mobile terminal is connected with earphone, and the method specifically may include steps of:
Step 101, when earphone stops playing audio signal, receives the environment noise gathered；
Stop playing audio frequency wherein it is possible to control earphone, to avoid the interference to Noise Acquisition of audio frequency that earphone plays.This
Sample, when earphone stops output audio signal, it is possible to gather the noise under user surrounding environment, i.e. environment noise, complete to make an uproar
Sound is sampled.
Step 102, is analyzed described environment noise, obtains target noise sound pressure level；
Wherein it is possible to this environment noise to be done certain analyzing and processing, thus obtain the sound that this environment noise is corresponding
Arbitrarily downgrade, i.e. target noise sound pressure level；
Step 103, according to the mapping relations of default noise sound with maximum output volume, determines described target noise
The maximum output volume that sound pressure level is corresponding；
Wherein it is possible to search should target make an uproar in the mapping relations of maximum output volume in default noise sound
Several earphone maximum output volumes arbitrarily downgraded, complete the setting of the volume upper limit.
Wherein, the maximum output volume obtained matches with the noise sound of the environment noise under current environment, then
The volume of the audio frequency that earphone is exported not only will not be submerged in environment noise, and can provide protection to human ear.
Step 104, is controlled the max volume of the audio signal that described earphone exports, and makes described max volume be less than

The excessive situation that human ear is caused damage of output volume that the volume of end is brought.
So, the environment noise that on the one hand embodiment of the present invention is gathered by reception controls the maximum sound of earphone output
Amount, on the other hand carrys out the sound of output current to earphone also by the actual acoustic pressure data in the people's external ear passage receiving detection in real time
Amount regulates in real time.So that the embodiment of the present invention is when exporting audio frequency, it is possible to the noise of surrounding is real with earphone
The volume of border output combines and regulates earphone output volume in real time and control so that the volume energy of output described in earphone
The enough audition to human ear is protected, and does not results in any damage, and nor affect on audio frequency listens to experience simultaneously.
With reference to Fig. 2, it is shown that the flow chart of the method for the protection human ear audition of another embodiment of the present invention, the method should
For mobile terminal, described mobile terminal is connected with earphone, and the method specifically may include steps of:
Step 201, when earphone stops playing audio signal, receives the environment gathered in the first predetermined amount of time and makes an uproar
Sound.
Wherein it is possible to add sound pressure sensor at earphone end (cavity portion of such as earphone), by this sound pressure sensor
In certain period of time, the environment noise around earphone is acquired by (such as 30 seconds), and then, this sound pressure sensor will be 30
The environment noise gathered in second is sent to mobile terminal.
Additionally, optional, in order to provide the user with the selection whether audition protected, before step 201, according to
The method of the embodiment of the present invention also includes: receive the predetermined registration operation of the user of described mobile terminal；True according to described predetermined registration operation
The operation of fixed the most whether starting protection human ear audition；When determining the operation starting described protection human ear audition, control described earphone
Stop playing described audio signal.
It is to say, the dresses such as the button of open and close protection human ear audition can be provided on mobile terminal or earphone
Put, if this button is arranged on " on " shelves by user, then according to the system identification information 0 that these " on " shelves are corresponding, then can be true
Determine user and start the operation of protection earphone audition；And if this button has been arranged on " off " shelves by user, then according to this
The system identification information 1 that " off " shelves are corresponding, then may determine that user closes the operation of protection earphone audition；When starting guarantor
When protecting the operation of human ear audition, it is possible to control earphone according to identification information 1 and stop output audio signal, make earphone quiet
Sound, it is simple to the above-mentioned sound pressure sensor collection to environment noise, it is to avoid the interference of audio frequency play by earphone.
Step 202, is filtered described environment noise processing, obtains making an uproar at the bottom of periodic noise and environment.
Wherein, owing to environment noise having impact noise in short-term, in order to ensure the accuracy of noise energy level, move
Dynamic terminal needs to be filtered environment noise processing, and filters out impact noise and other interference noises, obtains periodic noise
Make an uproar with at the bottom of environment.
Step 203, calculates the amplitude made an uproar at the bottom of described periodic noise and described environment, obtains target amplitude；
Wherein it is possible to the amplitude made an uproar at the bottom of periodic noise and environment is averaged obtain described target amplitude.
Step 204, carries out quantification treatment to described target amplitude；
Wherein, need target amplitude is multiplied by a quantitative levels for follow-up step 205 so that the target after quantization
Amplitude is when being converted into sound pressure level, and the rank of the two adapts.
Step 205, the described target amplitude after quantifying is converted to described target noise sound pressure level.
Wherein, owing to target amplitude is a kind of signal of telecommunication, it only can represent the amplitude of noise, and is listened for human ear
For the volume of the sound arrived, need to be determined by sound pressure level, and sound is a kind of acoustical signal.Accordingly, it would be desirable to will
Target amplitude (that is, the signal of telecommunication) after quantization is converted to sound pressure level (i.e. target noise sound pressure level, acoustical signal).The most just can lead to
Cross sound pressure level to the sound size that judges these environment noises and sound how.
Step 206, according to the mapping relations of default noise sound with maximum output volume, determines described target noise
The maximum output volume that sound pressure level is corresponding.
Wherein, step 206 can be accomplished by: defeated with maximum at default noise sound numerical range
Go out in the mapping relations of amplitude corresponding to volume, search the target noise sound pressure level numerical value model that described target noise sound pressure level is corresponding

Wherein, the sound pressure sensor of earpiece side (such as 50 milliseconds) can bear human ear is actual in certain period of time
Acoustic pressure data detects in real time；So this mobile terminal is receiving the people that sound pressure sensor detects in 50 milliseconds in real time
After actual acoustic pressure data in external ear passage, it is possible to this actual acoustic pressure data is analyzed, so that it is determined that wink in 50 milliseconds
Time acoustic pressure maximum, i.e. average sound pressure in maximum instantaneous acoustic pressure, and 50 milliseconds, average sound pressure here is also referred to as the most in short-term
Average sound pressure.Wherein, due to it needs to be determined that short-time average acoustic pressure, therefore, when real-time detection practical acoustic pressure data, need the
In two predetermined amount of time, wherein, the unit of time of this second predetermined amount of time is millisecond.
Step 209, compares described actual acoustic pressure data with default acoustic pressure threshold value；
Wherein, described step 209 can realize in the following manner: described maximum instantaneous acoustic pressure and first is preset
Acoustic pressure threshold value is made comparisons, and obtains the first comparative result；Described average sound pressure and second are preset acoustic pressure threshold value make comparisons, obtain
Two comparative results.
Step 210, controls the current volume of described earphone output audio frequency according to comparative result.
Wherein, described step 210 can realize in the following manner: when described maximum instantaneous acoustic pressure is more than described the
One presets acoustic pressure threshold value, and when described average sound pressure presets acoustic pressure threshold value less than described second, reduces described earphone output sound
The current amplitude (i.e. the pattern by reducing the internal output volume of mobile terminal reduces the sound pressure amplitude of output) of frequency；When described
Maximum instantaneous acoustic pressure presets acoustic pressure threshold value more than described first, and described average sound pressure presets acoustic pressure threshold value more than described second
Time, the user of described mobile terminal is carried out protecting the prompting operation of audition, that reduces described earphone exports working as of audio frequency simultaneously
Front amplitude；And if described maximum instantaneous acoustic pressure presets acoustic pressure threshold value less than described first, and described average sound pressure again smaller than
Described second when presetting acoustic pressure threshold value, then it represents that human ear will not be impacted by current volume, and mobile terminal does not make any prompting
And process, normally export audio signal.
Wherein, the described mode reminding operation can be carrying in the main screen region of described mobile terminal display protection audition
The information of waking up；Or, output represents the prompting sound of protection audition；Or, make described mobile terminal shake.Certainly, above-mentioned three kinds
The mode reminding operation can be with combination of two or three combinations.It is to say, user is carrying out protecting the prompting behaviour of audition
When making, can be reminded by the interactive portion of mobile terminal, wherein, interactive portion include mobile terminal interface prompt,
Terminal voice output prompting and terminal vibration prompting.
By means of the technical scheme of the above embodiment of the present invention, the embodiment of the present invention can when environment noise is processed,
To filter by impact noise in short-term, thus ensure the accuracy of noise energy level；Further, since user use earphone impedance and
Various compositions in sensitivity and music all differ, therefore, after combining environmental noise sets the max volume of earphone,
Also need to monitor the actual acoustic pressure of human ear, thus the volume of reality output is regulated in real time, it is achieved hearing user is had
Effect protection.Meanwhile, when the actual acoustic pressure data of human ear of in real time monitoring, to acoustic pressure and threshold value relatively need distinguish instantaneous maximum
Acoustic pressure and short-time average acoustic pressure compare respectively, so that the amplitude of the audio signal exported is optimum, are beneficial to user
Audition protect.
