Noise ration value, be calculated after current time, second setting quantity noise ration value；Wherein, second setting
The time interval of the noise ration value of quantity is identical as the sampling period of the setting；
Specifically, the noise of the environment as locating for intelligent video equipment is the dynamic amount changed constantly, if working as
When the preceding moment arrives, current time ambient noise is acquired, and calculate noise ration value, then further according to the noise ration
Value adjusts the volume of intelligent video equipment, due to ambient noise real-time change, it is likely that the intelligent shadow at the current time after adjusting
Sound device voice volume has been not suitable with the noise ration at current time.So in the reference note for calculating current time intelligent video equipment
Before, first an average measuring and calculating should be done to ambient noise volume value whithin a period of time to pass through that is, before current time arrives
The mode of prediction calculates the noise ration value at current time, to basis work as in time when current time arrives
The noise ration value at preceding moment adjusts the volume of intelligent video equipment.
For example, noise ration value of the embodiment of the present invention according to the noise of 10 sampling periods acquisition before current time,
The noise ration value in 3 sampling periods after current time is calculated, specific results of measuring is as shown in Figure 3.Specifically, adopting
With any one prediction algorithm, such as neural network algorithm, the number calculated after current time according to data with existing can be realized
According to purpose.
S205, it is saved in the period for being included according to the sampling period for falling back setting quantity since current time
Noise ration value, with it is described second setting quantity noise ration value, current time noise ration value is calculated；
Specifically, the embodiment of the present invention is calculated current time noise ration value, that is, is sought using the method averaged
The average value that the noise ration value of quantity and the noise ration value of the second setting quantity are set before the current time, makees
For the noise ration value at current time.
In embodiments of the present invention, 10 noise ration values before calculating current time are made an uproar with 3 after current time
The average value of sound magnitude, the noise ration value as current time.
S206, according to the current time noise ration value, the reference note of the intelligent video equipment is calculated.
Specifically, the method calculated is: being adjusted on the basis of current time noise ration value, obtain intelligent video
The reference note of equipment；The standard of adjustment is: reference note is higher by the range of ambient noise volume, human ear can be allowed clearly to differentiate ring
Border noise and program audio, and guarantee to listen to not ear-piercing when the program audio.
Such as: when ambient noise volume value is less than 50 decibels, it is higher than ambient noise volume value 8 that reference note, which adjusts standard,
Decibel；When ambient noise volume value is greater than 50 decibels less than 70 decibels, it is higher than ambient noise volume that reference note, which adjusts standard,
10 decibels of value；When ambient noise volume value is greater than 70 decibels, it is higher than ambient noise volume value 10-15 that reference note, which adjusts standard,
Decibel etc..It should be noted that in view of using the object of intelligent video equipment different, due to human ear to the susceptibility of sound not
Together, above-mentioned adjustment standard can adjust at any time according to the actual situation.
