Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not
For limiting the application.
Noise source detection method provided by the present application, can be applied in application environment as shown in Figure 1.Wherein, it handles
Device 102 is connect by cable with transaudient probe 104, and transaudient probe 104 is separately positioned on public power distribution room 106 and resident room

Give processing unit 102.
Wherein, processing unit 102 can be, but not limited to be various personal computers, laptop, smart phone, plate
Computer and portable wearable device.
In one embodiment, as shown in Fig. 2, providing a kind of noise source detection method, comprising the following steps:
Step 202, by the way that the transaudient probe of the predeterminated position and resident of public power distribution room within doors is arranged in, respectively to institute
The noise of public power distribution room and the resident within doors is stated to be sampled to obtain noise data, and generate the public power distribution room with
And the wavy curve of the noise in the resident room.
Wherein, the wavy curve is used for the mathematical relationship in reaction time and noise size, and transaudient probe includes for remembering
Sound recording sound signal or convert voice signal among the noise transducer, sound transducer and microphone of electric signal at least one
Kind, the transaudient probe reference record and stores noise data characterized by voltage or electric current, can continuously record 24 hours or more.
Step 204, the effective acoustic pressure Pe and A sound level curve are determined according to the wavy curve, and is had according to described
Effect acoustic pressure Pe and the A sound level curve determine the relevance between the noise of the public power distribution room and the resident within doors.
It, can be respectively from temporal associativity and extreme value association it should be noted that after obtaining Pe and A sound level curve
Property on curve is analyzed, wherein A sound level is one of sound level meter weighted, is the main standard that current noise is judged,
In the 1930s, people just choose from equal loudness contour to directly measure reflection people with instrument to the sensation of loudness of noise
40 sides, 70 sides, 100 sides this three curve, are devised by the inverse curve of this three curves by the electronic devices group such as resistance, capacitor
At weighting network, be arranged on sound level meter, so that sound level meter is respectively provided with A, B, C character of weighting.Specifically, two kinds of which are such as
Shown in lower.
Temporal associativity, can be according to the effective acoustic pressure Pe and the public power distribution room of the A sound level tracing analysis and resident
Relevance between daytime and night noise variation tendency within doors.Specifically, described in being determined according to the wavy curve
Effective acoustic pressure Pe and A sound level curve, analyzing the public power distribution room and the resident, the noise at daytime and night changes within doors
Trend is more than the first preset threshold when the public power distribution room and resident room daytime and night noise variation tendency matching degree
When, determining has relevance between the noise of the public power distribution room and the resident within doors.
For example, as shown in figure 3, Fig. 3 be if public power distribution room and resident it is long when noise A sound level curve, make an uproar
Sound value is always public power distribution room internal noise in the noise of 70dB or more 1, and another is noise 2.In conjunction with the curve at two
Noise carry out temporal associativity analysis, it can be seen that the A sound level of noise 1 is totally more stable, about 80dB or so, daytime and
Night variation tendency is unobvious；The A sound level of noise 2 is generally lower than noise 1, and at 22,30 when assigning to next day 5, and noise level is bright
It is aobvious to be lower than other times section, therefore assert that the two noise source does not have relevance in time.In another example if it find that public match
The noise variation tendency in electric room and 80% or more the noise variation tendency in resident room are noises that is identical, then both can determining
Has relevance in time.Certainly, this 80% be presetting value, can be set as different according to different situations
Numerical value, between 50% to 100%.
Extreme value relevance can determine A described in the effective acoustic pressure Pe and A sound level curve comparison according to the wavy curve
The position and time that the extreme value of sound level curve occurs determine the relevance of public power distribution room and resident within doors between noise.Specifically
For, can the A sound level curve according to the effective acoustic pressure Pe and the A sound level curve comparison extreme value occur position with
Time, if extreme point position that the public power distribution room and the noise of resident within doors occur on the A sound level curve and time
Similarity when being more than the second preset threshold, determine to have between the noise of the public power distribution room and the resident within doors and be associated with
Property.
For example, as shown in figure 3, Fig. 3 be public power distribution room and resident it is long when noise A sound level curve, noise figure
It is always public power distribution room internal noise in the noise of 70dB or more 1, another is noise 2.For example, the A sound level curve of noise 1
Overall steady, significant extreme value points are seldom；Noise 2 fluctuates obviously, and significant extreme value points are extremely more, hence it is evident that are more than noise 1.And
And the time point that the two extreme value occurs is entirely different, therefore assert that the two noise source does not have relevance in extreme value.In another example
If the public power distribution room and the noise of the resident within doors extreme point position occurred on the A sound level curve are similar to the time
When degree is more than 80%, determining has relevance between the noise of the public power distribution room and the resident within doors.Certainly, this 80%
For presetting value, different numerical value can be set as according to different situations, between 50% to 100%.
Step 206, the multistage noise of the public power distribution room and the resident within doors is chosen according to the wavy curve
Data simultaneously carry out fast discrete Fourier transform FFT, and the public power distribution room and the resident are determined from obtained frequency domain figure
The relevance between noise within doors.
Optionally, after determining relevance, it can assert public power distribution room property relevant with the noise source of resident within doors, this
When, reasonable solution can be proposed with regard to the relevance, and execute the measure and inhibit with the noise to public power distribution room.
It should be noted that the noise data collects, and after carrying out fast discrete Fourier transform FFT transform, can obtain
To frequency domain figure corresponding to the respective multistage noise data of public power distribution room and the resident room, i.e., to the two in frequency domain correlation
Property analysis, by frequency domain map analysis both can know whether relevant property.Specifically, when the public power distribution room and living
The multistage noise of family within doors determines the public power distribution room and institute when the frequency component matching degree on frequency domain figure is more than 80%
Stating has relevance between the noise of resident within doors.Certainly, this 80% be presetting value, can be set according to different situations
For different numerical value, between 50% to 100%.
As can be seen that the application is continuously measured based on the long-time to public power distribution room and the noise of resident, and according to
Measure obtained noise data and generate wavy curve, then determine corresponding Pe and A sound level curve, and combined data analysis and
The comparison of characteristic parameter, so that the relevance of the noise source to public power distribution room with resident within doors makes that, so that it is determined that making an uproar
Sound source whether be public power distribution room transformer.
It should be understood that although each step in the flow chart of Fig. 2 is successively shown according to the instruction of arrow, this
A little steps are not that the inevitable sequence according to arrow instruction successively executes.Unless expressly state otherwise herein, these steps
It executes there is no the limitation of stringent sequence, these steps can execute in other order.Moreover, at least part in Fig. 2
Step may include that perhaps these sub-steps of multiple stages or stage are executed in synchronization to multiple sub-steps
It completes, but can execute at different times, the execution sequence in these sub-steps or stage, which is also not necessarily, successively to be carried out,
But it can be executed in turn or alternately at least part of the sub-step or stage of other steps or other steps.
It should be noted that three kinds of judgment modes can be combined judgement in the application, i.e. generalized time phase simultaneously
When Guan Xing, extreme value correlation and frequency domain correlation, only three meet simultaneously, public power distribution room and resident can be just assert within doors
Noise source have relevance.Citing is illustrated below, referring to Fig. 4, Fig. 4 is the noise source detection side of the embodiment of the present application
